Description  
Applications  
The ST890B, ST890C and ST890D are low  
voltage, P-channel MOSFET power switches  
intended for high side load switching applications.  
PCMCIA slots  
Access bus slots  
Portable equipment  
These switches operate 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.
