BQ20Z45DBTR-R1

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 Track™

DESCRIPON

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.
