Single_supply_fault_monitor

Published:2009/7/24 4:56:00 Author:Jessie | From:SeekIC

This circuit shows an overvoltage/undervoltage fault monitor for a single supply, using an ICL7665S detector. Figure 9-15B shows the pin connections. The overvoltage trip point is centered around 5.5V, with the undervoltage trip at about 4.5 V. Both points have some hysteresis to prevent erratic output on/off conditions. The two outputs are connected in a wired-Ok signal. Harris Semiconductor, Linear& Telecom ICs, 1991, p 2-131 2137.2138.
