... Reversal Polarity Protection • Load-dump Protection 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 independent of the supply voltage, V 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 An unused comparator input must be connected to pin 7 ...
