•
Next Generation Patented Impedance Track™  
Technology Accurately Measures Available  
Charge in Li-Ion and Li-Polymer Batteries  
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.

Supports SHA-1 Authentication  
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.
