Hi,
Looks like the BQ27505YZGT-J5 is going EOL or at least NRND. I have been using it because of the small footprint. I would be interested in finding out about replacements - perhaps parts that use the same Impedance Track Algorithm and the newer ones that use Dynamic Voltage Correlation. Along with that I would be interested in complementary parts for battery charging and battery protection for a single Li Ion battery.
