Functional Diagram

Description

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.

OUT

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 short-

circuited 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.
