NCP335

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

ON Semiconductor 

NCP334, NCP335

2A Ultra-Small Controlled

Load Switch with

Auto-Discharge Path

The 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.

Features

• 1.2 V – 5.5 V Operating Range

• 47 mW P MOSFET at 3.3 V

• DC Current Up to 2 A

• Output Auto−discharge (NCP335)

• Active high EN pin

• WLCSP4 0.96 x 0.96 mm

• ESD Ratings: 4 kV Human Body Model, 2 kV CDM,

• 250 V Machine Model

• These are Pb−Free Devices

Typical Applications

• Mobile Phones

• Tablets

• Digital Cameras

• GPS

• Portable Devices
