The LTC1696ES6#PBF is a standalone power supply Over-voltage Monitor and Protection Device designed to protect a power supply load in the event of an over-voltage fault. It monitors two adjustable output voltages. If an over-voltage condition is detected, the output drives either an external SCR crowbar or turns off external back-to-back N-channel MOSFETs, thereby, disconnecting the input voltage from the power supply. Pin 6 offers three functions. By connecting a capacitor to this pin, the internal glitch filter time delay can be programmed. Without the capacitor, the default time delay is determined by an internal capacitor. This pin also serves as a reset input to clear the internal latch after an over-voltage fault condition. By pulling it high, the OUT pin is activated if the FB1 and FB2 voltages remain below the trip threshold.
