HM9701A

150mΩ Power Distribution Switches

■ General Description

■ Package

The HM9701A is an integrated 150mΩ power switch for

self-powered and bus-powered Universal Series Bus (USB)

applications. A built-in charge pump is used to drive the

N-channel NMOSFET that is free of parasitic body diode to

eliminate any reversed current flow across the switch when

it is powered off. Its low quiescent supply current (23µA)

and small package (SOT-23-5) is particularly suitable in

battery-powered portable equipment.

Several protection functions include soft start to limit inrush

current during plug-in, current limiting at 900Ma or 600mA,

and thermal shutdown to protect damage under over

current conditions.
