Preliminary
LINEAR INTEGRATED CIRCUIT
OVERLOAD MONITORING
WITH RESISTIVE LOAD,
VT = 44.5 mV
„ DESCRIPTION
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.
„ FEATURES
* Two common reference comparators
* Tight threshold tolerance
* Constant threshold
* Output with NPN
* 8 kV - ESD protection
* Protection of reverse polarity
* Load-dump protection
