Global Mixed-mode Technology

Power Distribution Switch

Features

General Description

The G5250S is an integrated power switch for

self-powered and bus-powered Universal Serial Bus

(USB) applications.

70mΩ High-Side MOSFET

Operating Range:2.7V to 5.5V

1mS Typical Rise Time

Fast Overcurrent Response 1.5µs (TYP.)

Under voltage Lockout

130µA Quiescent Supply Current

1µA Maximum Shutdown Supply Current

No Reverse Current when Power Off

Deglitched Open-Drain Over-Current Flag

Several Protection features include current limiting and

thermal shutdown to prevent catastrophic switch fail-

ure caused by increasing power dissipation when con-

tinuous 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 eliminate any

reversed current flow across the switch when it is pow-

ered off. When the output voltage is higher than input

voltage, the power switch is turned off by internal out-

put reverse-voltage comparator.

OC is open-drain output report over-current or

over-temperature event and has typical 9ms deglitch

timeout period. In addition, OC also reports output

reverse-voltage condition with typical 5ms deglitch

timeout period.
