WS4623C Image Sensor
Instructions

WS4623C
3A, 19 m, 300nA Quiescent current, and 100nA Standby current Load Switch

Descriptions

The WS4623C is a single channel load switch with ultra-low on-resistance MOSFET. It is designed for load switching applications with ultra-low quiescent current (300nA) and ultra-low standby current (100nA). The device is controlled by an external logic pin, allowing optimization of battery life, and portable device autonomy.
The WS4623C contains a P-channel MOSFET that can operate over an input voltage range of 1.2V to 5.5V and can support a maximum continuous current of 3A.
The WS4623C is available in a small 1 x 1.5mm CSP-6L Package. Standard products are Pb-free and Halogen-free.

Features

Input Voltage Range:1.2V~5.5V
Main switch Ron: 19m @ 4.5V
Maximum Output current: 3A.
Quiescent current : 300nA @ Typ
Standby current: 100nA @ Typ
