ICL7665 Microprocessor Voltage Monitor, DIP-8

The ICL7665 is a microprocessor voltage monitor that offers robust overvoltage and undervoltage detection with low power consumption. Designed for battery-operated and line-powered systems, it features dual comparators with precision internal references. This device is highly configurable, allowing users to program trip points and hysteresis using external resistors. Operating with a quiescent current of only 3µA, the ICL7665 is suitable for low-power applications where energy efficiency is critical. It supports supply voltages from 1.6V to 16V and features N-channel and P-channel open-drain outputs for flexible system integration. Its compact 8-pin DIP package ensures easy PCB mounting and minimizes board space. Applications include µP voltage monitoring, low-battery detection, power-fail alarms, and more.
