Note: For the Hall inputs, the input high state is defined to be the
state where the (+) input is higher than the corresponding
() input by 0.01 V or higher, and the input low state is
defined to be the state where the (+) input is lower than
the corresponding () input by 0.01 V or higher.
Note: Since this drive technique is a 180 current application
scheme, the phases other than the sink and the source
phases will not turn off.

W-phase Hall output
Used for output current detection. The current limiter circuit operates using the resistor (Rf) connected between
this pin and ground.
Note that the lower side saturation prevention circuit operates according to the voltage that appears on this pin.
Since the over-saturation level is set by this voltage, the response of the lower side saturation prevention circuit
may be degraded in the large current region if the value of Rf is made extremely small.
Note: The "H" state for FR is defined as a voltage of 8 V or
higher, and the "L" state for FR is defined as a voltage of
4 V or lower. (When V
CC
= 12 V.)

give rise to accidents or events that could endanger human lives, that could give rise to smoke or fire,
or that could cause damage to other property. When designing equipment, adopt safety measures so
that these kinds of accidents or events cannot occur. Such measures include but are not limited to protective
circuits and error prevention circuits for safe design, redundant design, and structural design.
