Dual Power Distribution Switch

Features

General Description

The G5258 is an integrated dual channel 87mΩ power

switch for self-powered and bus-powered Universal

Serial Bus (USB) applications.

87mΩ High-Side MOSFET

Available with 4 Versions of Current Limits with

Foldback

Operating Range:2.7V to 5.5V

400µS Typical Rise Time

Under voltage Lockout

65µA Quiescent Supply Current

1µA Maximum Shutdown Supply Current

Logic Level Enable Pin, Available with

Active-High or Active-Low Version

No Reverse Current to VIN when Power Off

VOUT OFF Discharge

Several Protection features include current limiting

with foldback, and thermal shutdown to prevent catas-

trophic switch failure caused by increasing power dis-

sipation when continuous heavy loads or short circuit

occurs. And a built-in charge pump is used to drive the

N-channel MOSFET that is free of parasitic body diode

to eliminate any reversed current flow across the

switch when it is powered off.

Deglitched Open-Drain Over-Current Flag

OC is open-drain output report over-current or

over-temperature event and has typical 9ms deglitch

timeout period.
