Preliminary
LINEAR INTEGRATED CIRCUIT
OVERLOAD MONITORING
WITH RESISTIVE LOAD,
V_T = 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 V_T is 44.5 mV and V_{4, 6}=V_S-V_T. V_T is not
dependent of the power supply voltage V_S. If the voltage
developed across shunt resistor R_SH exceeds V_T, 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
V_Z = 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
