The ISL88042 is a Quadruple voltage-monitoring supervisorcombining compeTITIve reset threshold accuracy and lowpower consumpTIon. This device combines popular funcTIonssuch as Power-On Reset, Undervoltage Supply Supervision,reset signaling and Manual Reset. Monitoring four differentsupplies in a 8 Ld 2x3 TDFN package, the ISL88042 devicescan help to lower system cost, reduce board spacerequirements, and increase the reliability of multi-voltagesystems.Low VDD detection circuitry protects the user’s system fromlow voltage conditions, resetting the system when VDD orany of the other monitored power supply voltages fall belowtheir respective minimum voltage thresholds. The resetsignal remains asserted until all of these voltages return toproper operating levels and stabilize.Two of the four voltage monitors have preset thresholds foreither dual 3.3V or one each for one 5V and one 3.3Vsupplies. Users can adjust the threshold voltages of the thirdand fourth voltage monitors in order to meet specific system level requirements.
