APPLICATION INFORMATION

The schematic shows a typical bq2083âV1P2-based battery pack application. The circuit consists of the bq29311

analog front end (AFE) IC, LED display, temperature measurement network, data flash connections, serial port,

and the sense resistor. The data flash stores basic battery pack configuration information and measurement

calibration values. The data flash must be programmed properly for bq2083âV1P2 operation. Table 13 shows the

data flash memory map and outlines the programmable functions available in the bq2083âV1P2.
