The is an overvoltage protection controller in 6 in TSOT-23 package. This standalone power supply overvoltage monitor and protection device is designed to protect power supply load in the event of an overvoltage fault. It monitors two adjustable output voltages. If an overvoltage 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 power supply. By connecting capacitor to pin 6 of LTC1696, the internal glitch filter time delay can be programmed. The default time delay is determined by an internal capacitor without the capacitor. This pin also serves as a reset input to clear the internal latch after an overvoltage fault condition. By pulling it high, the OUT pin is activated if the FB1 and FB2 voltages remain below the trip threshold.
