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. A single external capacitor sets
the fault indication delay, eliminating false outputs due to switching
noise, logic transition current spikes, and short-term AC line interrup-
tions. An additional comparator referenced to 2.5V allows the AC line
to be monitored for undervoltage conditions or for generation of a line
clock.
undervoltage lockout in a switching power supply. Uncommitted
collector and emitter outputs permit both inverting and non-inverting
operation. External availability of the precision 2.5V reference and
open-collector logic outputs permit expansion to monitor additional
voltage using available open-collector quad comparators.
