NCP334FCT2G

电源开关 IC - 配电 2A LOAD SWITCH WITHOUT DI

2A Ultra-Small Controlled  Load Switch with  Auto-Discharge Path

The NCP334FCT2G NCP334 and NCP335 are low Ron MOSFET controlled by  external logic pin, allowing optimization of battery life, and portable  device autonomy. 

Indeed, due to a current consumption optimization with PMOS structure, leakage currents are eliminated by isolating connected IC’s on the battery when not used. 

Output discharge path is also embedded to eliminate residual voltages on the output rail in the NCP335. 

Proposed in wide input voltage range from 1.2 V to 5.5 V, and a very small 0.96 x 0.96 mm WLCSP4, 0.5 mm pitch.
