nn Multifunction TIMER/RESET Pin The LTC®1696 is a standalone power supply overvoltage monitor and protection device designed to protect a
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
the power supply. nn 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
overvoltage fault condition. By pulling it high, the OUT
pin is activated if the FB1 and FB2 voltages remain below …
