Description

General part information

ST890 Series

The ST890 device 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.
