产品概述 返回TOPRgj嘉泰姆
The CXAS42263 is an integrated 120mΩ power switch 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. CXAS42263 has shutdown
discharge function when power switch is off. The typical
pull low resistor is 75Ω.
Its low quiescent supply current and small package
(SOT-23-5) is particularly suitable in battery-powered
equipment, like PDA, mobile phone.
