DESCRI PT I ON

The UTC UU4793 is a bipolar integrated circuit designed for

monitoring over loading or short circuit in automotive or industrial

applications. The threshold VT is 44.5 mV and V4, 6=VS-VT. VT is not

dependent of the power supply voltage VS. If the voltage

developed across shunt resistor RSH exceeds VT, IC turns on the

output, or else turns off the output.

The output is turned off when input switch Pin 8 is open or there

is a lack of power supply voltage. The output breakdown voltage is

decided by the Z-diodes Z3 and Z5 which have a typical value of

VZ = 22 V.

A not used of the comparator input have to be connected to

Pin 7.
