NCP331 Datasheet, PDF (1/8 Pages) ON Semiconductor – Soft-Start Controlled Load Switch with Auto Discharge

NCP331
Soft-Start Controlled Load
Switch with Auto Discharge
The NCP331 is a low Ron N−channel MOSFET controlled by a
soft−start sequence of 2 ms for mobile applications. The very low
R_DS(on) allows system supplying or battery charging up to DC 2A.The
device is enable due to external, active high, enable pin.
Due to a current consumption optimization, leakage current is
drastically decreased from the battery connected to the device,
allowing long battery life.
