NiCd or NiMH Gas Gauge Module

with Charge-Control Output

Features

Complete bq2014 Gas Gauge solution for NiCd or

NiMH battery packs

Charge-control output allows communication to

external charge controller (bq2004)

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

bq2114. The bq2114B-KT or bq2114LB-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.

General Description

2) Menu-driven software with the bq2114 to display

charge/discharge activity and to allow user inter-

face to the bq2014 from any standard DOS PC.

The bq2114 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 bq2114 incorporates a bq2014 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 bq2114L includes five surface-

mounted LEDs to display remaining capacity in 20% in-

crements of the learned capacity (relative mode). The

LEDs are activated with the onboard push-button

switch.

3) Source code for the TSR.

Pin Descriptions

DQ/Serial communication port

BAT+/Battery positive/pack positive

CHG/Charge control output

EMPTY/Empty indicator output

GND/Ground

Contacts are provided on the bq2114 for direct connec-

tion to the battery stack (BAT+, BAT-), the serial com-

munications port (DQ), the empty indicator (EMPTY),

and the charge control output (CHG). Please refer to the

bq2014 data sheet for the specifics on the operation of

the Gas Gauge.

PACK-/Pack negative

Unitrode configures the bq2114 based on the informa-

tion requested in Table 1. The configuration defines the

number of series cells, the nominal battery pack capac-

ity, and the self-discharge rate.

BAT-/Battery negative

5/99 B
