Features

General Description

90mΩ High-Side MOSFET

The G547 is an integrated power switch for

(G547E,G547F,G547G,G547H, G547M)

self-powered and bus-powered Universal Serial Bus

Available with 5 Versions of Current Limits with (USB) applications. G547E, G547F, G547G,G547H

Foldback

Operating Range:2.7V to 5.5V

1mS Typical Rise Time

Fast Overcurrent Response -3µs (TYPICAL)

Under voltage Lockout

100µA Quiescent Supply Current

1µA Maximum Shutdown Supply Current

Logic Level Enable Pin, Available with

Active-High or Active-Low Version

No Reverse Current when Power Off

and G547M are 90mΩ RDS(ON).

Several Protection features include current limiting with

foldback, and thermal shutdown to prevent catastrophic

switch failure caused by increasing power dissipation

when continuous heavy loads or short circuit occurs. A

built-in charge pump is used to drive the N-channel

MOSFET that is free of parasitic body diode to elimi-

nate 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
