mitsumi audio MM1407 figure c. watchdog timer basically, the watchdog timer monitors the level (3) of the current it impresses on the external capacitor. the charging time is determined by c1 and i2 in the block diagram, and control is done by input signal (1). when the first "h" trigger (input signal) chargers the external capacitor and level (3) goes over (4) "h" threshold value, output is first inverted (l h). while the input signal is being continuously impressed, the timer repeats charging current impress/stop to the external capacitor, but if input signal (1) is not impressed within the set time (clock monitoring time), charging to the external capacitors is stopped and the capacitor starts discharge operation. then level (3) falls below "l" threshold value and output (5) is again inverted (h l). 1. wakeup pin input signal cycle limit use at 1/ta or higher, 100hz or lower. t1: clock monitoring time (the time from wakeup signal input stop until logic truth table wakeup switches to low.) 2. wakeup pin input signal amplitude limit use at 1.5v or higher, 5v or lower. 3. external capacitor time constant (sets clock monitoring time) determined by t1 = 1.638 c f r [ ].
