Description

The ST890B, ST890C and ST890D are low

voltage, P-channel MOSFET power switches

intended for high side load switching applications.

These switches operate 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.
