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.
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.
