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 lim...
