Part Number : BQ28550
Function : Single Cell Li-Ion Battery Gas Gauge and Protection
Package : SON-12 Pin Type
Maker : Texas Instruments
The Texas Instruments bq28550-R1 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-R1 requires host microcontroller firmware support for implementation. A system processor communicates with the bq28550-R1 using a serial interface to obtain remaining battery capacity, system run-time predictions, and other critical battery information.
