bq2110

NiCd or NiMH Gas Gauge Module

Features

Complete bq2010 Gas Gauge solution for NiCd or

NiMH battery packs

Battery information available over a single-wire

bidirectional serial port

Battery state-of-charge monitoring for 4- to 12-cell

series applications

On-board regulator allows direct connection to the

battery

“L” version includes push-button activated LEDs to

display state-of-charge information

Nominal capacity and cell chemistry pre-configured

Compact size for battery pack integration

A module development kit is also available for the

bq2110. The bq2110B-KT or bq2110LB-KT includes one

configured module and the following:

General Description

1) An interface board that allows connection to the se-

rial port of an AT-compatible computer.

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.

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.

Pin Descriptions

DQ/Serial communication port

BAT+/Battery positive/pack positive

No connect

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.

EMPTY/Empty indicator output

GND/Ground

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.
