Description

The ST890 is a low voltage, P-channel MOSFET

power switch intended for high side load switching

applications.

The switch operates with inputs from 2.7 V to

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

systems.

The internal current limiting circuitry protects the

input supply against overload. The thermal

overload protection limits power dissipation and

junction temperatures.

The maximum current limit is 1.2 A. The current

limit through the switch is programmed with a

resistor from SET to ground. The devices are

available in SO-8 and DFN8L (3 x 3 mm)

packages.
