General Description
The bq2110 Gas Gauge Module provides a complete and
compact solution for capacity monitoring of NiCd and
NiMH battery packs. Designed for battery pack integra-
tion, the bq2110 incorporates a bq2010 Gas Gauge IC, a
current sense resistor, and all other components neces-
sary to accurately monitor and display the capacity of 4
to 12 series cells.
The bq2110L includes six surface-
mounted LEDs to display remaining capacity in 20% in-
crements of the learned capacity (relative mode) or pro-
grammed capacity (absolute mode). The sixth LED is
used in absolute mode to represent an overfull condition
(charge above the programmed capacity). The LEDs are
activated with the onboard push-button switch.
Contacts are provided on the bq2110 for direct connec-
tion to the battery stack (BAT+, BAT-), the serial com-
munications port (DQ), and the empty indicator
(EMPTY). Please refer to the bq2010 data sheet for the
specifics on the operation of the Gas Gauge.
Unitrode configures the bq2110 based on the informa-
tion requested in Table 1. The configuration defines the
number of series cells, the nominal battery pack capac-
ity, the self-discharge rate, and the LED display mode.
A module development kit is also available for the
bq2110. The bq2110B-KT or bq2110LB-KT includes one
configured module and the following:
1)
An interface board that allows connection to the se-
rial port of an AT-compatible computer.
2)
Menu-driven software with the bq2110 to display
charge/discharge activity and to allow user inter-
face to the bq2010 from any standard DOS PC.
3)
Source code for the TSR.
