General Description

The G547 is an integrated power switch for self-powered and bus-powered Universal Serial Bus (USB) applications. G547E, G547F, G547G,G547H 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 eliminate any reversed current flow across the switch when it is powered off.

OC is open-drain output report over-current or over-temperature event and has typical 9ms deglitch timeout period.

Applications

High-Side Power Protection Switch

*: 1 F 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.

TDFN3X3-8

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.
