U4793B
Overload Monitoring with Resistive Load, VT = 44.5 mV
Description
The IC U4793B in bipolar circuit, is designed to monitor
overload or a short circuit in automotive or industrial
applications. The threshold is tied to V4,6 = VS – VT
whereas VT = 44.5 mV. It is independent of the supply
voltage, VS. If the voltage drop across shunt resistor, Rsh,
exceeds this value, the output is turned on, otherwise the
output is turned off.
Without supply voltage or open input Pin 8, the output is
turned off. The output breakdown voltage is determined
by the Z-diodes Z3 and Z5 with a typical value of
VZ = 22 V.
A not used comparator input must be connected to Pin 7.
