U4793B
1. Description
The bipolar U4793B is designed to monitor overload or a short circuit in automotive or
industrial applications. The threshold is tied to V
4,6
= V
S
鈥?V
T
where V
T
= 44.5 mV. It is
independent of the supply voltage, V
S.
If the voltage drop across shunt resistor, R
sh
,
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 break-
down voltage is determined by the Z-diodes Z
3
and Z
5
with a typical value of V
Z
= 22V.
An unused comparator input must be connected to pin 7.
