ST890 1.2 A current limited high side power switch with thermal shutdown

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.

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
