I use an RRC2054-2 battery for the supply of my conception, which is a Li-Ion rechargeable battery, and is designed to communicate with a host or a charger through the System Management Bus (SMBus) protocol. In other words, the communication with the battery is based on the principals of operation of I²C.
Do you have one or more integrated circuits with those that I can communicate with my battery? Even better if you already have a schematic with TI components.
In summary, I would like to develop a digital interface for this battery.
Regards.
