Smart Battery Module With LEDs

The BQ219XL Smart Battery Module provides a com- plete solution for the design of intelligent battery packs. The BQ219XL uses the SMBus protocol and supports the Smart Battery Data commands in the SMB/SBD specifi- cations. Designed for battery pack integration, the BQ219XL combines the BQ2092 or BQ2040 Gas Gauge IC with a serial EEPROM on a small printed circuit board. The board includes all the necessary components to ac- curately monitor battery capacity and communicate critical battery parameters to the host system or battery charger. The BQ219XL also includes four LEDs The push-button Switch activates the LEDs to show remain- ing battery capacity in 25% increments. Contacts are provided on the BQ219XL for direct connec- tion to the battery stack (B+, B-) and the two-wire inter- face (C, D). Please refer to the BQ2092 or BQ2040 data sheet for specific information on the operation of the Gas Gauge and Communication Interface Unitrode configures the BQ219XL based on the informa- tion requested in Table 1. The configuration defines the pack voltage, capacity, and chemistry and charge control parameters. The Smart Battery Module uses the onboard sense resistor to track charge and discharge ac- tivity of the battery pack. Figure 1 shows how the mod- ule connects to the cells. By Texas Instruments
