Preliminary bq219XL

Smart Battery Module with LEDs

Features

➤

Complete smart battery solution for NiCd, NiMH,

and Li-Ion battery packs

➤

Based on the bq2092 or bq2040 Gas Gauge IC

Ideal for DR35 or DR36 type packs

Narrow board fits in the crevice formed by two

adjacent battery packs

➤

Accurate measurement of available battery

capacity

Designed for battery pack integration:

–

Measures only 3.5 (L) x 0.3 (W) inches

parameters. The Smart Battery Module uses the

onboard sense resistor to track charge and discharge ac-

tivity of the battery pack. Figure 1 shows how the mod-

ule connects to the cells.

Includes Gas Gauge IC, configuration

EEPROM, and sense resistor

–

Four onboard state-of-charge LEDs with

push-button activation

A module development kit is also available for the

bq219XL. The bq219XLB-KT includes one configured

module and the following:

Low operating current for minimal battery

drain

1) An EV2200-92 or EV2200-40 interface board that

allows connection to the serial port of any AT-

compatible computer.

➤

Critical battery information available over two-wire

serial port

General Description

2) Menu-driven software to display charge/discharge

activity and to allow user interface to the Gas

Gauge IC and serial E²PROM from any standard

Windows 95 or 3.1x PC.

The bq219XL Smart Battery Module provides a com-

plete solution for the design of intelligent battery packs.

The bq219XL uses the SMBus protocol and supports the

Smart Battery Data commands in the SMB/SBD specifi-

cations. Designed for battery pack integration, the

bq219XL combines the bq2092 or bq2040 Gas Gauge IC

with a serial EEPROM on a small printed circuit board.

The board includes all the necessary components to ac-

curately monitor battery capacity and communicate

critical battery parameters to the host system or battery

charger. The bq219XL also includes four LEDs. The

push-button switch activates the LEDs to show remain-

ing battery capacity in 25% increments.

Contacts are provided on the bq219XL for direct connec-

tion to the battery stack (B+, B-) and the two-wire inter-

face (C, D). Please refer to the bq2092 or bq2040 data

sheet for specific information on the operation of the Gas

Gauge and communication interface.

STAT

Unitrode configures the bq219XL based on the informa-

tion requested in Table 1. The configuration defines the

pack voltage, capacity, and chemistry and charge control
