Overview

Features • 10 kV – ESD Protection • Two Comparators with Common Reference • Tight Threshold Tolerance • Constant Threshold • NPN Output • Interference and Damage-protection According to VDE 0839 and ISO/CD 7637 EMI Protection • 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 V4,6 = VS – VT where 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 t...
