G546A1PUF——致新授权代理商科瑞芯电子有限公司 原装现品
General Description
The G546 are integrated dual channel 87mΩ (G546X1,
G546X2) and 72mΩ (G546X3, G546X4) power
switchs for self-powered and bus-powered Universal
Serial Bus (USB) applications.
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. 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.
OC is open-drain output report over-current or
over-temperature event and has typical 9ms deglitch
timeout period.
