DESCRIPTION Next Generation Patented Impedance Track™
Technology Accurately Measures Available The bq20z45-R1 SBS-compliant gas gauge and
Chargein Li-Ion and Li-Polymer Batteries protection ICisa single IC solution designed for
battery-pack or in-system installation. The
– Better Than 1% Error Over the Lifetimeof bq20z45-R1 measures and maintains an accurate
the Battery record of available chargein Li-ion or Li-polymer
• Supports the Smart Battery Specification batteries using its integrated high-performance
SBS V1.1 analog peripherals, monitors capacity change, battery
Flexible Configuration for2to4 Series Li-Ion impedance, open-circuit voltage, and other critical
parametersof the battery pack as well and reports
and Li-Polymer Cellsthe informationto the system host controller overa
• Powerful 8-Bit RISC CPU With Ultralow Power serial-communication bus. Together with the
Modes integrated analog front-end (AFE) short-circuit and
• Full Arrayof Programmable Protection overload protection, the bq20z45-R1 maximizes
Features functionality and safety while minimizing external
component count, cost, and sizein smart battery
– Voltage, Current, and Temperature circuits.
• Satisfies JEITA GuidelinesThe implemented Impedance Track™ gas gauging
• Added Flexibilityto Handle More Complex technology continuously analyzes the battery
Charging Profiles impedance, resulting in superior gas-gauging
• Lifetime Data Logging accuracy. This enables remaining capacity to be
Supports SHA-1 Authentication calculated with discharge rate, temperature, and cell
aging all accounted for during each stageof every
• Complete Battery Protection and Gas Gauge cycle with high accuracy.
