Absolute Maximum Ratings are those values beyond which damage to the device may occur. Functional operation under these condition is not implied.
The ST890 is a low voltage, P-Channel MOSFET power switch intended for high side load switching applications.
This switch operates with inputs from 2.7V ti 5.5V, making it ideal for both 3V and 5V systems. Internal current limiting circuitry protects the input supply against overload. Thermal overload protection limits power dissipation and junction temperatures.
The ST890's maxmimum current limits is 1.2A. The current limit through the switch is programed with a resistor from SET to groung. The ST890 is available in SO-8 package. Main applications are: PCMCIA slots, Access bus slots, Portable equipment.
