Overview
The LTC2912ITS8-2#TRMPBF, produced by Analog Devices Inc., is a single undervoltage (UV) and overvoltage (OV) monitor designed to detect power supply voltage anomalies. This component is part of the supervisory circuits family and is particularly useful in ensuring the reliability and stability of power supplies in various electronic systems.
The device features lowpass filtering on its monitor inputs to reject transient voltages and ensure accurate detection of UV and OV events. It also includes an adjustable timeout period to ensure a minimum reset pulse width, allowing the monitored voltage to settle within the valid operating range after a fault has cleared.
