1.2A, Current-Limited, High-Side P-Channel Switch with Thermal Shutdown
General Description
The MAX893L smart, low-voltage, P-channel, MOSFET power switch is intended for high-side load-switching applications.

This switch operates with inputs from +2.7V to +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 temperature. The MAX893L's maximum programmed current limit is 1.2A. The typical short-circuit current is 1.5 times the programmed current; therefore, a 1.2A programmed limit will result in a 1.8A short-circuit current limit. The current limit through the switch is programmed with a resistor from SET to ground. The quiescent supply current is a low 13µA. When the switch is off, the supply current decreases to 0.1µA. The MAX893L is available in an 8-pin SO package.
