1
VCC
Power supply for all sections other than the output block.
10
VM
Power supply that provides the output power.
2, 8
RF
Output current detection pin. The output current is converted to a voltage for detection by a resistor connected between this
pin and GND.
11
GND
Ground for all sections other than the output block.
The Rf pin voltage will be the lowest output transistor potential.
12
FSR
Forward/stop/reverse control pin.
The voltage on this pin controls the IC forward, stop, or reverse operation.
Forward : 0 to 0.8V
Stop :
2.1 to 2.9V
Reverse : 4.2 to 5.0V
