GENERAL DESCRIPTION

The TDA5149G is a combination of a voice coil motor
driver and a spindle motor pre-driver, capable of operating
12 V high-performance hard disk drives.

The device integrates a spindle pre-driver that drives three
external N-channel power MOSFETs in order to drive a
three-phase brushless, sensorless DC motor in full wave
mode. In the normal mode, commutations are generated
from the internal Back EMF (BEMF) sensing circuitry.
Commutations, however, can also be generated from an
external source, thereby providing the possibility of driving
the motor in the stepper-motor mode.

The VCM driver is a linear transconductance amplifier
capable of handling currents up to 1.65 A. It allows
external adjustment of the gain and compensation.
The TDA5149G also contains two drivers for a latch that
secures the heads in the event of power-down.

To control functions such as park, brake, sleep or disable
and to program the different timing parameters, the
TDA5149G is provided with a three-wire serial port. A high
precision voltage monitor is also included, for both
5 and 12 V power supplies. Finally, the IC contains a
temperature monitor circuit and an uncommitted
operational amplifier connected to V

, which can be used

freely within the application. The device is contained in a
LQFP64 package with 4 pins connected to the lead frame
for improved heat dissipation.

spindle motor pre-driver combination chip

TDA5149G

FUNCTIONAL DESCRIPTION

Spindle

The spindle section contains both the low and high side
pre-drivers for a three phase DC brushless motor.
The digital commutation control, using the timing
information provided via the serial port, is responsible for
the proper switch-on and switch-off of the external power
FETs. It is also responsible for selecting the correct BEMF
comparator.

For optimum power efficiency, a continuous PWM method
is used to control the average current from the power
supply to the motor coils. This PWM mode, by controlling
the average power supply current, produces a lower
torque ripple and thus lower audible noise. In order to
reduce further acoustic noise the TDA5149G is provided
with a soft switching circuit to turn-on and turn-off linearly
the switching current under PWM control. The switching
transition time is controlled by the digital commutation
circuit and is fixed to 50% of the time between two
zero-crossings, i.e. 30

of the electrical revolution.

Soft switching is achieved by activating, during
commutation, a free-running duty-cycle modulator
controlled by a linearly decreasing voltage across a
capacitor. This will reduce the current smoothly in the
off-going leg to zero. In conjunction with this additional
PWM open loop, the average current control regulates the
sum of the current in the off-going and on-going leg.

This method requires two PWM control loops; one to
control the average current (main loop) and one to control
the current in the off-going leg. The swapping of the two
loops is realized with a pair of analog switches that are
sequentially switched by the digital commutation circuitry.

The PWM control also causes PWM pulses on the back
EMF. These pulses disturb correct sensing of the back
EMF for the zero-crossing detection. Consequently,
edge-triggered latches are inserted behind the back EMF
comparators, thus ensuring reliable back EMF sensing.

In the SPINMODE, programmable via the serial bus, the
user can feed their own commutation pulses to the
pre-drivers and control the motor in the stepper-motor
mode. The commutation pulses are applied to the
TDA5149G via the serial bus by setting the COMMCLK bit
successively to logic 1 and logic 0.

The different control modes of the TDA5149G can be
commanded via the serial bus. These modes are as
follows:

Sleep mode: all analog circuits, except the power supply
monitor, are switched off to reduce the power
consumption of both the 12 and 5 V supplies.

Disable mode: the output voltage of all pre-drivers is
LOW thus the external power MOSFETs are not
conducting.

Brake mode: all low side pre-drivers are turned on
(output voltage HIGH) thus switching on the low-side
power MOSFETs. In this way the back EMF voltage of
the motor is short-circuited to ground.

Voice coil motor

The VCM is a linear, symmetrical, class AB, H-bridge type
power amplifier with all power devices on-chip. The driver
is a transconductance amplifier that controls the output
currents up to 1.65 A. The driver is constructed in a
master-slave configuration with the zero current level
internally adjusted in such a way that it corresponds to the
middle of the output swing. Moreover, the gain of the slave
has been made greater than 1 in order to ensure full
saturation of the driver output VCM+.

The gain of the closed loop is programmable, using the
V

GAINSEL

bit. This bit can be programmed via the serial

bus. A sense resistor (R

) allows the measurement of the

VCM current. The voltage across this resistor is connected
to an accurate sense amplifier with a typical gain of 5.
The output of the sense amplifier (V

CMSENSOUT

) is fed back

to the input of the VCM amplifier. Because of the symmetry
of the circuit, the compensation network can be connected
between the VCM1 input and the VCM

output.

Control modes such as VCM-BRAKE, VCM-DISABLE and
VCM-PARK can be controlled via the serial bus.

Latch drivers

The TDA5149G provides the possibility of driving an
external latch to secure the VCM heads. There are two
modes; the activate mode (LACTIVE) and the hold mode
(LHOLD). The hold mode is used to preserve power.
Both modes are controlled via the serial bus. The drivers
are switched off during the SLEEP mode or in the event of
a power-down.

TDA5149G

Power-on/power-off reset

The power-on reset circuitry monitors the analog, digital
and general supplies. The voltage thresholds have been
set internally for both supplies, i.e. 4.4 V for V

DDA

and

DDD

, and 10.5 V for V

. External adjustment and

filtering, to suppress supply spikes, has been made
possible through the pins POR5

ADJ

and POR12

ADJ

When either of the supplies falls below their threshold
levels, the reset circuit provides two active LOW output
signals. The RESETA signal is a full CMOS output and the
RESETP signal has an active pull-down MOS transistor
with a passive pull-up resistance of 10 k

. The latter can

be used for emulation purposes. Both signals remain LOW
until the supply voltages are again above the threshold
level, delayed by a time constant period that is determined
by the value of the capacitor connected to pin POR

DELAY

A park sequence is initiated on a reset fault. This includes
disabling the actuator latch drivers and starting a delayed
spindle brake operation by switching on the low side
pre-drivers simultaneously. This brake delay is determined
by an external RC combination connected to
BRAKEDELAY. Actuator PARK and spindle BRAKE can
also be controlled via the serial port.

At power-up, the two reset output signals (RESETA and
RESETP) will remain LOW as long as either supply
voltage is below the specified threshold plus the hysteresis
voltage. Once the supply voltages are above their specific
trip levels, the two reset signals become HIGH after the
power-on reset delay (POR

DELAY

). This delay time is

determined by the value of the capacitor connected to the
POR

DELAY

pin.

Powerless park/brake

As with the normal retract procedure, an actuator park
sequence is initiated whenever a power-down situation
occurs. The power-on/power-off reset circuit generates the
two active LOW reset signals and also activates the VCM
park circuit. The VCM park circuit provides a voltage,
retrieved from the rectified back EMF voltage of the
running-out spindle, of 1.2 V (typ.) to the VCM pin.
The voltage at pin VCM+ is 0 V. This voltage is supplied by
the capacitor C

CLAMP

that is connected to the CLAMP pin.

This capacitor smooths the rectified back EMF and stores
the electrical energy generated by the motor.

To ensure that the stored energy in the clamp capacitor is
only used for the park operation, the CLAMP input must be
isolated from the power supply. This can be achieved by
using a Schottky diode or a reverse connected N-channel
power FET (see Fig.1). The TDA5149G provides an
output H0 to control this power FET.

At power-down the brake delay circuit is also enabled.
The brake delay circuit is supplied by the energy stored in
the capacitor (charged during normal operation from V

)

that is connected to the BRAKEPOWER pin. Both the
BRAKEDELAY and BRAKEPOWER pins are then isolated
from the 12 V supply voltage. When the voltage on the
BRAKEDELAY pin reaches a value of 1.6 V (typ.), the
low-side external power FETs are turned on to brake the
spindle motor. The BRAKEPOWER capacitor then
supplies the current to keep the power FETs conducting.
This means that the voltage on this capacitor decreases
with time.

Serial port

The serial port is used to modify the various operational
modes of the TDA5149G and to adjust the timing
parameters to ensure the proper commutation sequence
of the spindle motor. It is a synchronous, slave only,
three-wire communication port with data (SDATA), clock
(SCLOCK) and enable (SENABLE) inputs.

The serial port requires the data to be sent in bytes, the
LSB (data 0) to be sent first and the MSB (address 2) last.
The three most significant bits (MSBs) determine the
register address, the remaining five bits represent the
data, which means up to 8 registers can be independently
addressed.

When SENABLE is LOW, the serial port is disabled and
the IC is not affected by any change both on SDATA and
SCLOCK. When SENABLE is HIGH the data is written
serially to the shift register on the rising edge of SCLOCK.
When SENABLE goes LOW the shifting sequence is
stopped and the last 8 bits that are clocked in are latched
into the appropriate control register. Therefore, the
transmission of two consecutive bytes requires that
SENABLE is LOW for at least a duration of `t'
(see Chapter "Characteristics").

The start-up timer instigates the spin-up in the absence of the back EMF zero
crossings. If the rotational speed is high enough, the commutations are
sequenced regardless of the start-up counter. But if no BEMF zero crossing
occurs, which is the case if the motor is stationary or rotating very slowly, the
start-up timer reaches its terminal count given by the STARTUP_REG, thereby
causing the next commutation. If t

HANDLING

Inputs and outputs are protected against electrostatic discharge in normal handling. However, to be totally safe, it is
desirable to take normal precautions appropriate to handling MOS devices.

ESD according to MIL STD 883C - method 3015 (HBM 1500

, 100 pF) 3 pulses positive and 3 pulses negative on each

pin versus ground - Class 1: 0 to 1999 V.

SOLDERING

Introduction

There is no soldering method that is ideal for all IC
packages. Wave soldering is often preferred when
through-hole and surface mounted components are mixed
on one printed-circuit board. However, wave soldering is
not always suitable for surface mounted ICs, or for
printed-circuits with high population densities. In these
situations reflow soldering is often used.

This text gives a very brief insight to a complex technology.
A more in-depth account of soldering ICs can be found in
our

"IC Package Databook" (order code 9398 652 90011).

Reflow soldering

Reflow soldering techniques are suitable for all LQFP
packages.

Reflow soldering requires solder paste (a suspension of
fine solder particles, flux and binding agent) to be applied
to the printed-circuit board by screen printing, stencilling or
pressure-syringe dispensing before package placement.

Several techniques exist for reflowing; for example,
thermal conduction by heated belt. Dwell times vary
between 50 and 300 seconds depending on heating
method. Typical reflow temperatures range from
215 to 250

Preheating is necessary to dry the paste and evaporate
the binding agent. Preheating duration: 45 minutes at
45

Wave soldering

Wave soldering is not recommended for LQFP packages.
This is because of the likelihood of solder bridging due to
closely-spaced leads and the possibility of incomplete
solder penetration in multi-lead devices.

If wave soldering cannot be avoided, the following
conditions must be observed:

A double-wave (a turbulent wave with high upward
pressure followed by a smooth laminar wave)
soldering technique should be used.

The footprint must be at an angle of 45

to the board

direction and must incorporate solder thieves
downstream and at the side corners.

Even with these conditions, do not consider wave
soldering LQFP packages LQFP48 (SOT313-2),
LQFP64 (SOT314-2) or LQFP80 (SOT315-1).

During placement and before soldering, the package must
be fixed with a droplet of adhesive. The adhesive can be
applied by screen printing, pin transfer or syringe
dispensing. The package can be soldered after the
adhesive is cured.

Maximum permissible solder temperature is 260

C, and

maximum duration of package immersion in solder is
10 seconds, if cooled to less than 150

C within

6 seconds. Typical dwell time is 4 seconds at 250

A mildly-activated flux will eliminate the need for removal
of corrosive residues in most applications.

Repairing soldered joints

Fix the component by first soldering two diagonally-
opposite end leads. Use only a low voltage soldering iron
(less than 24 V) applied to the flat part of the lead. Contact
time must be limited to 10 seconds at up to 300

C. When

using a dedicated tool, all other leads can be soldered in
one operation within 2 to 5 seconds between
270 and 320
