Package Pin Description

PACKAGE PIN #

PIN SYMBOL

FUNCTION

8 Lead PDIP

1VFB

The VFB pin is the inverting input to the on-chip operational

amplifier.

Filter

The Filter pin is the non-inverting input to the on-chip opera-

tional amplifier.

Signal Common

The Signal Common pin connects to +VS/2, to a 20k½ resistor

tied to VFB and to a 10k½ resistor tied to Filter.

Gnd

The Gnd pin is the power return terminal

SCR Trigger

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.

6+VS

The +VS pin is the power input to the IC.

AmpOUT

The AmpOUT pin is the output of the on-chip operational ampli-

fier.

Detect

The Detect pin is the fault detector input.
