PGIN
max2.0V
min1.0V
(when VCC=3V)
PG amplifier input.
Connect PG coil between this pin and
VREF.
14
VREF
Internal 1.3V reference voltage.
Used as reference voltage for FG and PG
amplifiers.
15
FGIN_D
max2.0V
min1.0V
(when VCC1=3V)
FG amplifier input.
Connect FG coil between this pin and
VREF.
18
STBY_D
0 to VCC1
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.
17
FRC_D
0 to VCC1
Drum motor forward/reverse rotation select
pin.
Low: forward
(-0.2V to 0.7V or open)
High: reverse
(2V to VCC1)
5
VS_D
0V to VCC2
Power supply for determining output
amplitude by supplying drum motor voltage.
Must be lower than VCC2 voltage.
