Power supply for power amplifier systems other
than motor drive transistors. Power supply pin
that provides voltage for blocks other than control
blocks supplied by V

ANGLE
Connect a resistor between this pin and GND.
Changing the value of this resistor will change the
Hall input-output gain (motor waveform slope).

All circuits can be made inoperative either by
connecting this pin to GND, or by leaving it open.
In that state the supply current will be
approximately 0 μA. Hold at 2 V or higher during
normal operation.
