Preliminary bq2150H

Li-Ion Power Gauge™ Module

Features

Complete bq2050H Power Gauge solution for Li-Ion

battery packs

Battery information available over a single-wire

(HDQ) bidirectional serial port

Control signals to enhance pack protection

Battery state-of-charge monitoring for 2- to 5-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 pre-configured

number of series cells, the nominal battery pack capac-

ity, and the Li-Ion battery type (coke or graphite anode).

Figure 1 shows how the module connects to the cells.

Compact size for battery pack integration

General Description

A module development kit is also available for the

bq2150. The bq2150HB-KT or the bq2150HLB-KT in-

cludes one configured module and the following:

The bq2150H Power Gauge Module provides a complete

and compact solution for capacity monitoring of Li-Ion bat-

tery packs. Designed for battery pack integration, the

bq2150 incorporates a bq2150H Gas Gauge IC, a current

sense resistor, and all other components necessary to accu-

rately monitor and display the capacity of 2 to 5 series

cells.

1) An EV2200-50H interface board that allows con-

nection to the serial port of an AT-compatible com-

puter.

2) Menu-driven software to display charge/discharge

activity and to allow user interface to the bq2150H

from any standard Windows 3.1x or 95 PC.

The bq2150L includes five LEDs to display remaining ca-

pacity in 20% increments of the learned capacity. The

LEDs are activated with the onboard push-button switch.

Pin Descriptions

Contacts are provided on the bq2150H for direct connec-

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

communications port (HDQ). The RBI input provides

backup power to the bq2150H in the event that the cells

are removed or the battery is turned off. The bq2150H

has a 1µF capacitor onboard connected to RBI to supply

backup power for about an hour. In battery packs that

use high-side FETs to control the charge/discharge of

the Li-Ion cells, the RBI input can be wired to a single

cell to provide prolonged data retention times. The SD

input allows an external signal (active low) to turn the

bq2050H IC off to minimize internal current consump-

tion of the battery pack and maximize storage life of the

pack in the system. When turned off, the bq2150H is

non-functional, and the RBI power source maintains

sheet for the specifics on the operation of the Gas Gauge.
