Advanced Load Management

Controlled Load Switch with Low RON

The NCP4547 load switch provides a component and area-reducing

solution for efficient power domain switching with inrush current

limit via soft start. It is designed to integrate control and driver

functionality with a high performance low on-resistance power

MOSFET in a single device. This cost effective solution is ideal for

power management and hot−swap applications requiring low power

consumption in a small footprint.

Features

• Advanced Controller with Charge Pump

• Integrated N−Channel MOSFET with ESD Protection

• Soft−Start via Adjustable Slew Rate Control

• Low On−Resistance

• Input Voltage Range 0.5 V to 6 V

• Low Standby Current

• Load Bleed Function

• No External Components Required

• Enable Pins with CMOS Input Levels

• This is a Pb−Free Device

Typical Applications

• Notebook and Tablet Computers

• Handheld Electronics

• Digital Cameras

• Portable Medical Devices

• Hard Drives

• Peripheral Ports
