Overview

19-1223; Rev 0; 4/97 Current-Limited, High-Side P-Channel Switches with Thermal Shutdown _______________General Description The MAX891L/MAX892L smart, low-voltage, P-channel, MOSFET power switches are intended for high-side load-switching applications.
These switches operate with inputs from 2.
7V to 5.
5V, making them ideal for both 3V and 5V systems.
Internal current-limiting circuitry protects the input supply against overload.
Thermaloverload protection limits power dissipation and junction temperatures.
The MAX891L/MAX892L’s maximum current limits are 500mA and 250mA, respectively.
The current limit through the switch is programmed with a resistor from SET to ground.
When the switch is o...
