I am designing a tiny device with very low power consumption. The device needs a rechargeable battery which should be charged from USB.
I have found LIR2032 and ML2032 batteries that can provide enough current to power the device. As I understand these two use different chemistry, so need different charging algorithm. Can one circuit support both LIR2032 and ML2032 without external switch? What protection and charging do each of the batteries require?
