Pin Function

Supplies power to all circuits except output

block.

Sets the C pin charge/discharge current.

3C

Sets the output off time and output current

neglect time during current limiter operation.

Output pin 1

Output pin 2

Output pin 3

Output current detection pin. By inserting

resistor Rf between this pin and GND, the

output current is detected as voltage. The

output current is limited to a current value set

by VRF/Rf (current limit operation).

Power supply pin providing output.

GND for other than output.

The minimum potential of output transistor is

the RF pin voltage.

Forward/reverse control pin.
