Application note
ST890: a high side switch
for PCMCIA and USB applications
Introduction
The ST890 is a low voltage, P-channel MOSFET power switch, intended for high side load
switching applications. Its main applications are PCMCIA slots, portable equipment and
access bus slots. The device is useful in all the applications that need a supply with short-
circuit protection and programmable current limitation, such as slots in which cards can be
connected and disconnected without turning off the power supply.
