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.

♦ Very Small Footprint (16-pin QSOP is the same

size as an 8-pin SO)

♦ Low Resistance: 45mΩ at 3V

♦ ±21%-Accurate, User-Set Current Limit

♦ 12µA (typ) Quiescent Current

♦ 0.01µA (typ) Shutdown Current

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.

♦ 0.04µA (typ) Leakage to Output when Switch

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.

♦ 2.7V to 5.5V Input Range

♦ Thermal Shutdown

♦ FAULT Output

Guide.
