Pin function
Motor counter EMF voltage FG
pulse pin.
Outputs a pulse using W phase
counter EMF voltage as FG.
Connect to ground if not used.
Loading motor power supply pin.
Stabilize against noise in the
same way as for VCC2.
Output transistor P–GND
Output current can be detected
for motor current control by
inserting a resistor between Rf
pin and ground.
Loading motor driver output pins.
Connect to loading motor.
L–FG amplifier input pins.
RLM1 and RLM2 are negative
input.
RLP1 and RLP2 are positive
input.
Pin voltage
2.2 to VCC2
0 to VCC1
