Hi,
I need to help for the fuel gauge circuit. The related circuit is added. My problem is the output voltage values (in my schematic, MSP_DVCC, MSP_AVCC values),
if I use lipo battery in my circuit (3.7V, 850mAh), the MSP_DVCC, and MSP_AVCC =0.6V nearly, or if I use USB connection with Microcontroller (MSP430f5529), in this case, MSP_DVCC, and MSP_AVCC =1.1 V nearly.
however, if ı measure the circuit, ı recognize that lipo battery is not charged over USB. because the battery voltage is not increased.
in my circuit, ı want to 3 volt in my output values (MSP_DVCC, and MSP_AVCC should be 3V),
What is the my error in my circuit ?
thanks for reply,
Sincerely,
