产品概述 返回TOPHQq嘉泰姆
The CXAS42273 is an integrated power switch for
self-powered and bus-powered Universal Serial Bus
(USB) applications.
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.
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.
