MM912_634 Advance Information, Rev. 4.0
This pin is the device power supply pin 1. VS1 is primarily supplying the VDDX
Voltage regulator and the Hall Sensor Supply Regulator (HSUP). VS1 can be
sensed via a voltage divider through the AD converter. Reverse battery protection
diode is required. See
This pin is the device power supply pin 2. VS2 supplies the High Side Drivers (HSx).
Reverse battery protection diode required. See
This pin is the first High Side output. It is supplied through the VS2 pin. It is designed
to drive small resistive loads with optional PWM. In cyclic sense mode, this output
will activate periodically during low power mode. See
