Overview
The LTC1696ES6#TRMPBF, produced by Analog Devices Inc., is a standalone power supply overvoltage monitor and protection device. It is designed to protect power supply loads from overvoltage conditions. This device monitors two adjustable output voltages and can trigger protective actions such as activating an external SCR crowbar or turning off external back-to-back N-channel MOSFETs to disconnect the input voltage from the power supply.
