The V_FB pin is the inverting input to the on-chip operational
amplifier.
The Filter pin is the non-inverting input to the on-chip opera-
tional amplifier.
The Signal Common pin connects to +V_S/2, to a 20k½ resistor
tied to V_FB and to a 10k½ resistor tied to Filter.
The Gnd pin is the power return terminal
The SCR Trigger pin drives the silicon controlled rectifier dur-
ing fault conditions. An internal 4.7k½ resistor between this pin
and Gnd holds the SCR off in non-fault conditions.
The +V_S pin is the power input to the IC.
The Amp_OUT pin is the output of the on-chip operational ampli-
fier.
The Detect pin is the fault detector input.
