Hi All,  

I'm currently using the BQ24616 as battery charger/power path manager in my design (an AM335X based embedded system), everything seems to work fine and I'm happy with the overall performance. 

The Battery Pack is:  Li-ion 7.4V 5200mAh 

System Power come from a 12V DC power supply.  

In the next revision on my design I'd like to measure the TOTAL System Power and the Battery Power (from/to the Battery) and send the data to my CPU over I2C. 

I'd like to take advantage of the two current-sense resistors already present in the design between ACN/ACP and SNR/SRN pins.

I'm thinking to use the T.I. INA219 ( Bidirectional, Zero-Drift, High-Side, I2C Out Current/Power Monitor) to measure current, voltage and power.

Are there any problems with my idea? Is the INA219 internal ADC (input bias current 20 μA , input impedance 320 kΩ) going to interfere with the BQ24616 functionality and accuracy? 

Thank you,

Salvo
