NCP340MUTBG Datasheet, PDF (1/9 Pages) ON Semiconductor – Soft-Start Controlled Load Switch

NCP340
Soft-Start Controlled Load
Switch
The NCP340 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 3A.The device is enable automatically if a Power Supply is
connected on Vin pin (active High) and maintained off if no Vin
(internal pull down).
Due to a current consumption optimization, leakage current is
drastically decreased from the battery connected to the device,
allowing long battery life.
