DESCRIPTION

protection limits power dissipation and junction

temperatures.

The ST890 is a low voltage, P-Channel MOSFET

power switch intended for high side load switching

applications.

This switch operates with inputs from 2.7V to

5.5V, making it ideal for both 3V and 5V systems.

Internal current limiting circuitry protects the input

supply against overload. Thermal overload

The ST890’s maximum current limits is 1.2A. The

current limit through the switch is programed with

a resistor from SET to ground. The ST890 is

available in SO-8 package. Main applications are:

PCMCIA slots, Access bus slots, Portable

equipment.
