Pin Name
Hall signal input pins from each motor
phase.
The logic high state is the state where
IN + > IN - .
If input is provided from a Hall IC, the
common-mode input range can be
expanded by biasing either + or -.
Power supply pin.
Insert a capacitor between this pin and
ground to prevent the influence of noise,
etc.
5V regulator output pin (control circuit
power supply).
Insert a capacitor between this pin and
ground for stabilization.
Undervoltage protection voltage
detection pin.
If a 5V or higher supply voltage is to be
detected, set the detection voltage by
insetting an appropriate zener diode in
series.
Synchronous rectification select pin.
A low-level input set up the IC with
synchronous rectification disabled, and
a high-level input synchronous
rectification enabled.
