Re: PIN pull-up while sleep consume to much power
Thanks Paul, trying to make no modification to the PCB even tough there is a VCC test pad close to the Reed Switch so a 1206 res could reach the pin, wake up the chip every 500mS, enable pull-up and check GP2 state, turn off pull-up and sleep again got it down 1.6 uA
PLVD, this module also consume a lot of power 24 uA, comparator pins not configured so it cannot check the battery.
There is a HIGH-PRECISION VOLTAGE DETECTOR S-1000 Series (2.2 V) on the PCB connected to MCLR what will reset the chip, how did the device use be able to report low battery state ? Once the batt dip below 2.2V the S-1000 it will just keep cycling the PIC, I think is to late to use PLVD compare VCC to VREF and report it.
