The MAX869L P-channel load switch features an accu-

rate user-set current limit and low on-resistance. This

switch is designed to protect your power source from

shorts and surges by limiting current and preventing

the system supply from being pulled low. The input volt-

age range is 2.7V to 5.5V.

The MAX869L features a 2A, 45mΩ switch controlled

by a logic signal. Current-limit accuracy is ±21%, and

can be set from 400mA to 2.4A using a single resistor.

The device has a low 12µA quiescent supply current,

which reduces to 2µA max in shutdown. It features ther-

mal-shutdown protection and a logic-signal output pin

(FAULT) that signals when there is an overcurrent or

overtemperature condition.

For other devices in this family, consult the Selector

Guide .
