Power Distribution Switch

Features

General Description

The G524 is an integrated power switch for

self-powered and bus-powered Universal Serial Bus

(USB) applications. G524A, G524B, G524C, G524D

70mΩ High-Side MOSFET

(G524A,G524B,G524C,G524D)

Available with 4 Versions of Current Limits with

Foldback

are 70mΩ R_DS(ON)

Operating Range:2.7V to 5.5V

1mS Typical Rise Time

Fast Overcurrent Response -1.5µs (TYPICAL)

Under voltage Lockout

130µA 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

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.

Output ( OC )

Available with or without Output Shutdown

Pull-low Resister

OC is an open-drain output report over-current or

over-temperature event and has typical 9ms deglitch

Output Reverse-Voltage Protection

SOT-23-5, TSOT-23-6, MSOP-8 and MSOP-8 (FD)

Packages

UL Certification_#E232223

CB Test Certification by IEC 60950-1:2005 (2nd

Edition); Am 1:2009

timeout period. In addition, OC also reports output

reverse-voltage condition with typical 5ms deglitch

timeout period.

*: 1µF of input capacitor is enough in most application cases.

If the PCB trace of power rail to IN is long, larger input capacitor is necessary.

Note: Recommend connecting the Thermal Pad to

the GND for excellent power dissipation.

Pin#6 should be considered as OUT when circuit design and PCB layout, but it is NC pin actually.
