DESCRIPTION

This device was designed to provide all the operational features of the SG1543/2543/3543 devices but with the added advantage of uncommitted inputs to the voltage sensing comparators. This allows monitoring of voltage levels less than 2.5 volts by dividing down the internal reference supply.

FEATURES

• Uncommitted comparator inputs for wide input flexibility

• Common-Mode range from zero to near supply voltage

• Reference voltage trimmed to 1% accuracy

• Over-voltage, under-voltage, and current sensing circuits all included

• SCR Crowbar drive of 300mA

• Programmable time delays

• Open-collector outputs and remote activation capability

• Total standby current less than 10mA

HIGH RELIABILITY FEATURES - SG1544

♦ Available to MIL-STD-883 and DESC SMD

♦ LMI level S processing available
