DM2060

The DM2060 Gas Gauge Demonstration Module provides a typical implementation for the bq2060 SBS v 1.1 Compliant Gas Gauge IC. The DM2060 incorporates a bq2060 IC, an EEPROM, a 30m sense resistor, and all other components necessary for gas gauge operation. Each DM2060 module is pre-programmed for the pack voltage, chemistry, and capacity, as outlined in Ordering Information.

The DM2060 includes 4 LEDs to display remaining capacity in 25% increments of the learned full capacity. The LEDs are activated with the onboard push-button switch.

Contacts are provided on the DM2060 for direct connection across the battery stack (B+, BAT-) and the individual series cells in a Li-Ion pack (CELL1P, CELL2P, CELL3P, and CELL4P). The SMBD (data) and SMBC (clock) are the SMBus communication lines. Figure 1 shows how to connect a DM2060 to a battery pack.
