The ICL7665AESA+ is a microprocessor voltage monitor with dual over/undervoltage detection in 8 pin NSOIC package. It warns microprocessors (μPs) when there is a 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.
