产品概述 返回TOPaJd嘉泰姆
The CXAS42264 is an 120mΩ power switch for
self-powered and bus-powered Universal Serial Bus
(USB) applications.
Several Protection features such as current limiting
with foldback, and thermal shutdown are included 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 makes it free of
parasitic body diode to eliminate any reversed current
flow across the switch when it is powered off. The
CXAS42264 has a shutdown discharge function when
power switch is turned off. User could realize the shutdown
discharge function by adding an external resistor
between OUT PIN and DSG PIN.
Its low quiescent supply current and small package
SOT-23-5 and ADFN1.5X1.5-6 is particularly suitable
in battery-powered equipment, like PDA, mobile phone.
