The BQ20Z45DBT-R1 is a SBS v1.1 compliant Gas Gauge with Impedance Track™ technology. It 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, 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. This enables remaining capacity to be calculated with discharge rate, temperature and cell aging all accounted for during each stage of every cycle with high accuracy.
● Better than 1% error over the lifetime of the battery
● Supports the smart battery specification SBS V1.1
● Added flexibility to handle more complex charging profiles
● Lifetime data logging
● Supports SHA-1 authentication
● Green product and no Sb/Br
