G524B2T11U-配电开关-芯片

General Description
The G524 is an integrated power switch for
self-powered and bus-powered Universal Serial Bus
(USB) applications. G524A, G524B, G524C, G524D
are 70mΩ RDS(ON).
Several Protection features include current limiting 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. When the output voltage is higher than input
voltage, the power switch is turned off by internal output

reverse-voltage comparator.
