BQ20Z45-R1 采用 Impedance TrackTM 技术符合 SBS 1.1 的电量监测计
BQ20Z45-R1 描述
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. Together with the integrated analog front-end (AFE) short-circuit and overload protection, the bq20z45-R1 maximizes functionality and safety while minimizing external component count, cost, and size in smart battery circuits.
