SG1548/SG2548/SG3548 QUAD POWER FAULT MONITOR 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 interruptions.
An additional comparator referenced to 2.
5V allows the AC line to be monitored for undervoltag...
