产品概述 返回TOPUTs嘉泰姆
The CXAS42266 is a current limited N-channel MOSFET
power switch designed for highside load switching
applications. The low RDS(ON) N-channel power
MOSFET is driven by a built-in charge pump which
generates a voltage higher than the supply voltage to
fully enhance the switch.
This switch operates with inputs ranging from 2.7V
to 5.5V, making it ideal for both 3.3V and 5V systems.
An integrated current-limiting circuit protects
the input supply against large current which may
cause the supply to fall out of regulation. The
CXAS42266 is also protected from thermal overload
which limits power dissipation and junction temperatures.
Current limit threshold is programmed
with a resistor from SET to ground. In shutdown
mode, the supply current decreases to less than
1μA. The reverse leakage current is also less than
1μA.
The GCXAS42266is available in a SOT-23-5 package
