M5DIN PowerOff when Vin is powered
-
Hi.
I begin to love the M5DIN but I think there is a hardware issue either by design or my unit is faulty. Running the factory test program on a battery runs fine for manual power off and RTC based wake up. When off, the red LED is off. As soon as I power it on Vin 12V (green connector) I can't power off the unit anymore. The led does in a dimmed state and from that moment I can't power on or off completely. This happens with and without the battery connected. It seems that the train of FETs are not switched off completely when powered by Vin - probably the charger is trying to supply the unit (and battery). I see the effect of the HOLD pin in my firmware going LOW when the LED goes from full brightness to low brightness but again, never a clean off state. I expected that then Vin is on, the unit powers on (which it does, and it's fine) but I can still go sleeping. With that issue here, once I'm in this semi-sleep (semi bright led) adding Vin back will not power it on so my program is out of control.
Is my understanding correct that this is a side effect in the design or is it just my unit that is faulty?
Does your unit switch off completely (led off) when on Vin?PS: I also think the schematic needs to be updates as I see confusing signal labels and it's not completely drawn
Many thanks.
