BQ20Z45-R1DBTR Datasheet PDF - TI

●DESCRIPTION

●The bq20z45-R1 SBS-compliant gas gauge and protection IC is a single IC solution designed for

●battery-pack or in-system installation. The bq20z45-R1 measures and maintains an accurate record of available charge in Li-ion or Li-polymer batteries using its integrated high-performance analog peripherals, monitors capacity change, battery impedance, open-circuit voltage, and other critical

●parameters of the battery pack as well and reports the information to the system host controller over a serial-communication bus.
