Output pin.
When the load is short-circuited and current in excess of the detection current (0.5A min) flows to the
output pin, the current limiter operates to protect the IC.
Ground pins.
Power pin.
Incorporates an overvoltage protection function which turns off the output when the voltage applied
exceeds 25V (min). Protects IC and load.
Incorporates 2V (typ.) hysteresis.
Input is CMOS-compatible, with pull-down resistor connected.
Even if the input is open, output will not accidentally turn on.
Ground pins.
Self-diagnosis detection pin. Goes low when overcurrent, overheating, or overvoltage is detected.
n-channel open drain.
