General Description
Two Pch MOSFETs for high side power switches, two Nch for
low side and one control IC are integrated into one package.
Enables to drive a motor by DC drive at up to 5ADC or by pulse
drive at up to 16A.
PWM input signal is 20 kHz max, and phase
changeover frequency is 500Hz max.
Input signals for IN1 and IN2 control the output of
each phase with normal, reverse, brake, and free-run
mode.
In order to prevent shoot through current during phase changeover,
the control IC set the dead time. Dead time: 20S (typ).
Versatile protection functions:
Over current protection for each power switch (Latch mode)
Thermal shutdown (TSD)
DIAG output function: Outputs the diagnosis during abnormal
operation.
Package---SPM
Applications
Driving various DC motors (PWM control)
Throttle valve for automotive application
Features
SI-5300 incorporates two high side Pch MOSFETs, two low side
Nch MOSFETs, and a control IC in one package.
Overcurrent protection function for each power switch, and thermal
shutdown function for control IC. Also, the dead time (20S) is set
in the control IC to prevent turning on the high side MOSFETs at
the same timing.

Note
*3 The standard value of Iocp is assumed to be a value by which the output of each power MOSFET cuts off.
When the protection circuit of OCP and TSD operates , power MOSFET's keeps cutoff.
When a signal(5V:H0V:L) is input to the terminal PWM , the cutoff operation will be released. Moreover ,
Three minutes ( Ta=25, fPWM=10Khz ,VM=14V) are assumed to be max at the over current state continuance
Time in the VM operation and ground of output terminal (OUT1,OUT2).
It is not the one to assure the operation including reliability in the state that the sort-circuit continues for
along time.
*4 DIAG signal output terminal is an collector output. Use apull-up resistor when connecting it to a logic circuit.
