‘Simple latching watchdog timer’
Based on a μP-supervisor/watchdog IC (MAX6749), the circuit described in this application note from Maxim Integrated Products provides a latched failure indication in response to a loss of the input pulse stream. The circuit can monitor a fan (based on the fan’s tachometer output), an oscillator or the software execution of a microprocessor.
