2A, Current-Limited, High-Side
P-Channel Switch with Thermal Shutdown
_______________General Description
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, 45m ? 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.
