Smart Battery Module With Leds And Pack Supervisor

  The BQ2148 Smaart Battery Module provides a complete and compact Battery Management solution for Li-Ion Battery packs. Designed for Battery pack integration, the bq2168 combines the bq2040H Gas Gauge IC with the BQ2058 Supervisor IC on a small printed circuit board. The board includes all the necessary components to accurately monitor Battery capacity and protect the cells from overvoltage, undervoltage, and overcurrent conditions. The board works with three or four Li-Ion series cells. The Gas Gauge IC uses the on-board sense Resistor to track charge and discharge activity of the Battery pack. Critical Battery information can be accessed through the serial Communications port at SMBC/SMBD. The BQ2148 uses the SMBus Communications protocol and supports the Smart Battery Data Commands in the SBD specification. The supervisor circuit consists of the BQ2058 and two FETs The BQ2058 controls the FETs to protect the batteries during charge/discharge cycles and short circuit conditions. The bq2168 provides contacts for the positive and negative terminals of each Battery in the stack. Please refer to the BQ2040 and BQ2058 data sheets for the specifics on the operation of the power gauge and supervisor ICs. 5/99 2) Pin
