Function

Power supply pin for blocks except output

C pin charge/discharge current set pin

Setting pin for current limiter output off time and output current ignore time

May be used for wiring

Output pin 1

Output pin 2

Output pin 3

Output current detection pin. Insert a resistor (Rf) between this pin and ground.

The output current will be limited to the value determined by VRF/Rf (output current limiter).

Power supply pin for output

Ground for blocks except output

Lowest electrical potential of output transistors is voltage at RF pin.

Forward/reverse control pin
