Pre-configured EEPROM

General Description

The DM2060 Gas Gauge Demonstration Module pro-

vides a typical implementation for the bq2060 SBS v 1.1

Compliant Gas Gauge IC. The DM2060 incorporates a

bq2060 IC, an EEPROM, a 30mΩ 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 ca-

pacity 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 connec

tion across the battery stack (B+, BAT-) and the individ

ual 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.

Re-Programming

Using the evaluation software, the DM2060 circuit mod

ules can be re-programmed for pack voltage, chemistry,

capacity, and other critical operating parameters. The

bq2060 data sheet and the EV2200-60 User’s Guide il

lustrate typical EEPROM programming for Li-Ion and

NiMH battery packs.
