BQ20Z60-R1 采用 Impedance Track™ 技术符合 SBS 1.1 的电量监测计
BQ20Z60-R1 描述
The bq20z60-R1 SBS-compliant gas gauge and protection IC, incorporating patented Impedance Track™ technology, is designed for battery-pack or in-system installation. The bq20z60-R1 measures and maintains an accurate record of available charge in Li-ion or Li-polymer batteries using its integrated high-performance analog peripherals. The bq20z60-R1 monitors capacity change, battery impedance, open-circuit voltage, and other critical parameters of the battery pack, which reports the information to the system host controller over a serial-communication bus. It is designed to work with the bq29330 analog front-end (AFE) protection IC to maximizes functionality and safety while minimizing external component count and cost in smart battery circuits.
