Quad power fault monitor

Silicon General's Type SGI548 is an integrated circuit capable of monitoring up to four positive DC supply voltages simultaneously for overvoltage and undervoltage fault condinons. An on-chip inverting opamp also allows rnonitoring one negative DC voltage. The fault tolerunce window is accuratel y programmable from ±2% to 40% using a simple divider network on the +2.5-V reference.
