MAX890L Datasheet (Maxim) - Current-Limited, High-Side P-Channel Switch

MAX890L, Current-Limited, High-Side P-Channel Switch

The MAX890L 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.
