BQ20Z95DBTR
SBS 1.1的电量监测计和保护已启用采用Impedance Track ™ SBS 1.1-COMPLIANT GAS GAUGE and PROTECTION ENABLED WITH IMPEDANCE TRACK⑩
DESCRIPON
The bq20z95 SBS-compliant gas gauge and protection IC is a single IC solution designed for battery-pack or in-system installation. The bq20z95 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 bq20z95 maximizes functionality and safety while minimizing external component count, cost, and size in smart battery circuits.
