ICL7665ACSA+T

The ICL7665ACSA+T is a microprocessor voltage monitor with dual over/undervoltage detection in 8 pin NSOIC package. It warns microprocessors (µPs) when there is an overvoltage and undervoltage condition. The 3µA quiescent current of the device makes it ideal for voltage monitoring in battery powered systems. The trip points and hysteresis of the two voltage detectors are individually programmed through external resistors to any voltage greater than 1.3V. In both battery and line powered systems, the unique combination of a reference, two comparators and hysteresis outputs reduces the size and component count of many circuits. It is typically used at µP voltage monitoring, low battery detection, power fail and brownout detection, battery backup switching, power supply fault monitoring, over/undervoltage protection and high/low temperature, pressure, voltage alarms.
