MAX869LEEE

2A，限流型，高边P沟道开关，带有热关断 2A, Current-Limited, High-Side P-Channel Switch with Thermal Shutdown

General Description

The MAX869L P-channel load switch features an accurate 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 voltage 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.
