DESCRIPTION

The SG1548 is an integrated circuit capable of monitoring up to four positive DC supply voltages simultaneously for overvoltage and undervoltage fault conditions. An on-chip inverting op amp also allows monitoring one negative DC voltage. The fault tolerance window is accurately programmable from ±5 to ±40 using a simple divider network on the 2.5V reference.

FEATURES

• Monitors four DC voltages and the AC line

• Precision 2.5V ±1 low-drift reference

• Fault tolerance adjustable from ±5 to ±40

• ±3 trip threshold tolerance over temperature

• Separate 10mA, 40V overvoltage, undervoltage and AC line fault outputs

• Fault delay programmable with a single capacitor

• 30mV comparator hysteresis to prevent oscillations

• On-chip inverting op amp for negative voltage

• Open-collector output logic or expandability

• Operation from 4.5V to 40V supply
