Building a fault detection device.
Once fault is detected device should not resume to normal working condition until and unless POWER is switch off for 30 Seconds.
If power is restored before 30 seconds ( after switching OFF ) it again goes in Fault state.
Device do not contain any battery and carry 56F8037 micro controller on board.
Solution 1:
I am thinking to charge a capacitor using a transistor switch n a GPIO of micro;
once the fault is detected and once power is switch off it should get discharged through a resistor which will take approximately 30 seconds to drain.
Before powering ON device the voltage across capacitor will be sensed using a GPIO.
If it still high fault detector will enter in FAULTY state else resume normal.
Can anyone find out what risk am running with this??
Or a better direction to work..
Thanks and regards.
