BQ20Z75-V180,pdf(SBS 1.1 Compl

The bq20z75-V180 SBS-compliant gas gauge and protecTIon IC is a single IC soluTIon designed for battery-pack or in-system installaTIon. The bq20z75-V180 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 bq20z75-V180 maximizes functionality, safety and minimize external component count, cost and size in smart battery circuits.
