Hi,
I just read the TI AAJ article "Improved LiFePO4 cell balancing in battery-backup systems with an Impedance Track™ fuel gauge" (slyt528). The article was very interesting and is relevant to my 4S LiFePO4 battery pack application. Similar to the article, my pack will undergo shallow discharge cycles with a maximum discharge rate in the order of 0.02C.
How would I go about getting the firmware referenced in the article or how would I setup my pack per the article using the factory default firmware?
GG IC: BQ20Z45-R1
Factory Firmware: 1.05
Cell Chemistry ID: 0439 (AA Portable LFP-18650-1500)
Cell Configuration: 4 series
Sincerely,
Doug Young
