SBS 1.1标准的电量监测计和保护 SBS 1.1-COMPLIANT GAS GAUGE AND PROTECTION
The is a SBS v1.1 compliant Gas Gauge with LED/LCD drive and Impedance Track™ technology designed for battery-pack or in-system installation. The BQ20Z655-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 gauge 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. Together with the integrated analog front-end AFE short circuit and overload protection, it maximizes functionality and safety while minimizing external component count, cost and size in smart battery circuits. The implemented Impedance Track™ gas gauging technology continuously analyzes the battery impedance, resulting in superior gas-gauging accuracy.
Device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
