ST890 Datasheet PDF - ST Microelectronics

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.

●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.
