ST890-1.2A current limiting thermal shutdown high side
The ST890 is a low voltage, P-channel MOSFET for power switching applications with high side switching loads. This switch takes a 2.7V TI5.5V input, ideal for 3V and 5V systems. An internal current limit circuit protects the input supply against overload. Thermal overload protection limits power dissipation and junction temperature. The highest required current limit for the ST890 is 1.2A. The current limit is programmed through the switch, with a resistor set to the groung. ST890 is SO-8 package. Main applications are: PCMCIA slot, access bus slot, portable equipment.
