Description
- DESCRIPTION
- The bq20z90 SBS-compliant gas gauge IC, incorporating patented Impedance Track™ technology, is designed for battery-pack or in-system installation. The bq20z90 measures and maintains an accurate record of available charge in Li-ion or Li-polymer batteries using its integrated high-performance analog peripherals. The bq20z90 monitors capacity change, battery impedance, open-circuit voltage, and other critical parameters of the battery pack, and reports the information to the system host controller over a serial-communication bus. It is designed to work with the bq29330 analog front-end (AFE) protection IC to maximize functionality and safety, and minimize component count and cost in smart battery circuits.
- FEATURES
- • Patented Impedance Track™ Technology Accurately Measures Available Charge in Li-Ion and Li-Polymer Batteries
- • Better than 1% Error Over Lifetime of the Battery
- • Instant Accuracy – No Learning Cycle Required
- • Automatically adjusts for battery aging, battery self discharge and temperature inefficiencies
- • Supports the Smart Battery Specification SBS V1.1
- • Works With the TI bq29330 Analog Front-End (AFE) Protection IC to Provide Complete Pack Electronics Solution
- • Full Array of Programmable Voltage, Current, and Temperature Protection Features
- • Integrated Time Base Removes Need for External Crystal with Optional Crystal Input
- • Electronics for 7.2-V, 10.8-V or 14.4-V Battery Packs With 50% Fewer External Components
- • Based on a Powerful Low-Power RISC CPU Core With High-Performance Peripherals
- • Integrated Field Programmable FLASH Memory Eliminates the Need for External Configuration Memory
- • Measures Charge Flow Using a High-Resolution, 16-Bit Integrating Delta-Sigma Converter
- – Better Than 0.65 nVh of Resolution
- – Self-Calibrating
- • Uses 16-Bit Delta-Sigma Converter for Accurate Voltage and Temperature Measurements
- • Extensive Data Reporting Options For Improved System Interaction
- • Optional Pulse Charging Feature for Improved Charge Times
- • Drives 3-, 4- or 5-Segment LED Display for Remaining Capacity Indication
