Hi all,
I need a circuit or a cheap IC to monitor Li-Ion battery voltage(2.9~4.25V) continuously without additional power supply, and it would be best that its power consumption is less than 10mA. I think two methods, but there exits faulty.
1) A/D sampling. There is not precision reference, as no additional power supply.
2) Comparator. It can only complete segment montoring, but not continuous monitoring.
Can anyone give me some advices?
Thanks in advance.
