Supply pin that determines the output amplitude.
This pin must be set lower than the VCC2 voltage.
Power amplifier system power supply for transistors
other than those that drive the motor.
Power supply voltage for control blocks other than
those provided by VCC1.
Power supply voltage for the Hall amplifier,
forward/reverse, FG amplifier, and thermal shutdown
circuits
All circuits are turned off by connecting this pin to
ground or leaving it open.
The current drain is about 0 μA in this mode.
Apply 2.0 V or higher for motor drive operation.
Connect a resistor between this pin and ground.
The Hall input/output gain can be changed by
changing the value of this resistor.
FG signal input
FG amplifier output
