I have a processor which needs to be powered on by pulling a pin LOW for 1 second. I would like to set the system up so that whenever a battery is present, the processor turns on. I have a programming background so I am having a little trouble turning ths into an analog design.
Here is what I have:
3.7V battery input (Li-ion), 900 - 1100mA, call it BAT
ON# pin, which needs to be pulled LOW for 1 second.
POWRMON pin, which is HIGH when the unit has been turned on OR ON# pin is pulled LOW.
