PG amplifier input.
Connect PG coil between this pin and
VREF.
Internal 1.3V reference voltage.
Used as reference voltage for FG and PG
amplifiers.
FG amplifier input.
Connect FG coil between this pin and
VREF.
When this pin is at 0.7V or lower or when it
is open, only the FG/PG amplifier operates.
In the motor drive state, the pin should be
at 2V or higher.
Drum motor standby pin.
Drum motor forward/reverse rotation select
pin.
Low: forward
(-0.2V to 0.7V or open)
High: reverse
(2V to V CC 1)
Power supply for determining output
amplitude by supplying drum motor voltage.
Must be lower than V CC 2 voltage.
