Pin function
PG amplifier input pin.
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 pin.
Connect FG coil between this pin
and VREF.
FG amplifier input signal noise
filter capacitor connection.
FG amplifier input signal noise
filter capacitor connection.
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.
