NiCd Or NiMH Gas Gauge Module With Fast-Charge Control

The BQ2164 Gas Gauge Module provides a complete and compact Battery Management solution for NiCd and NiMH battery packs. Designed for battery pack integration, the BQ2164 combines the BQ2014 Gas Gauge IC with the BQ2004 Fast-Charge IC on a small printed circuit board. The board includes all the necessary components to accu- rately monitor the capacity and reliably terminate fast charge of 5 to 10 series cells. The gas gauge IC uses the onboard sense resistor to track charge and discharge activity of the battery pack. The fast charge IC Gates a current-limited or constant-current charg- ing supply connected to PACK+. Charging termination is based on T/tor-V/PVD, maximum temperature, time, and voltage. The BQ2004 signals charge completion to the BQ2014 to indicate full capacity. The charge complete signal to the gas gauge eliminates the need to fully cycle the bat- tery pack to initially calibrate full pack capacity. Contacts are provided on the BQ2164 for direct connec- tion to the battery stack (BAT+, BAT-), the gas gauge's Communications port (DQ), and the thermistor (THERM+, THERM). The thermistor is required for temperature fast charge termination. Please refer to the BQ2004 and BQ2014 data sheets for the specifics on the operation of the gas gauge and the fast charge ICs.
