bq28550 Description
The Texas Instruments bq28550 battery gas gauge provides current and voltage protection, and secure, SHA-1/HMAC authentication for single-cell Li-Ion battery packs. Designed for battery-pack integration, the bq28550 requires host microcontroller firmware support for implementation. A system processor municates with the bq28550 using one of the serial interface configurations to obtain remaining battery capacity,...
