The MLX12101 serves as a protection circuit where sensible 5V IC's are supplied by long wires that can be short-circuited to the wiring harness of a car.
The IC is to be connected between a 5V supply, and a 5V powered remote application. The IC is set on the remote application side, its input receiving the 5V supply through the car wiring, and its output delivering the 5V protected supply to the local application.
When the input is below 5.5 Volt, the switch between 5V input and 5V output is closed and the application is powered. When the 5V input goes above 6.8 Volt (This case occurs when the supply wire is shortcircuited to battery plus), the output is shut off. When the chip input goes negative ( this is the case when the battery is reversed), a reverse polarity diode prevents the output of going negative.
