BQ20Z90评估模块EVM是对于bq20z90/bq29330/bq29410锂离子智能电池芯片的完整评估系统。该评估模块包含一个bq20z90/bq29330及独立二级过压保护BQ29410 ，与电流检测电阻和热敏电阻的电路模块。DescriptionThis EVM is a complete evaluation system for the bq20z90/bq29330/bq29410 Li-Ion smart battery chipset. The EVM includes one bq20z90/bq29330 and the independent 2nd level overvoltage protection bq29410, the circuit module with current sense resistor and thermistor. The circuit monitors and predicts capacity, performs cell balancing, monitors critical parameters, protects the cells from overcharge, over discharge, short circuit, and overcurrent in 2-, 3- or 4-series cell Li-Ion or Li-Polymer battery packs. The circuit module connects directly across the cells in a battery. With the EV2300 interface board and software, the user can read the bq20z90 data registers, program the chipset for different pack configurations, log cycling data for further evaluation and evaluate the overall functionality of the bq20z90/bq29330 and bq29410 solution under different charge and discharge conditions. An EV2300 board is required to interface this EVM with the PC and can be purchased separately. Please refer to the bq20z90EVM-001 User Guide and the datasheets of the bq20z90, bq29330 and bq29410 for full functional descriptions. The user guide has information on how to install the software, connect the evaluation setup, and use the main features of the evaluation kit. Features
