Tool/software:
May I control DELAY/M_DRV pin (pin 3) by two ways (manual switch or signal)?
If I can do it, how I need to design the circuit?
I want to control it by two ways as shown below to turn on the P-MOS.
1. Manual switch
2. Signal from ATSAMD21G18.
P-MOS need to turn ON every 1 hour, however the P-MOS turn ON every 10 minutes in this circuit.
Thank you for your reply.
I'll try your advice soon.
It seems to tha the cause of this problem is that PA23 pin is connected directly to DELAY pin.
Because this system works fine if the PA23 pin is not connected to the DELAY pin.
Therefore, I consider the tips provided to you to be very effective.
Thank you.
