This document describes the design considerations required to change a bq2040SN-C408 design to a bq2040-D411 solution. This includes both hardware and firmware considerations. Find the latest ordering information and data sheet on the world wide web at http://power.ti.com. - Wide-Vin Battery-Charger Using SMBus MSP430 MCUs and bq Fuel Gauges (Rev. A)PDF, 1.0 Mb, Revisión: A, Archivo publicado: jul 25, 2011
This application report describes a smart-battery charger reference design with a wide-input-voltage range. The reference design implements the System Management Bus (SMBus) protocol for communication between the MSP430 microcontroller and a SMBus-compatible battery fuel gauge. The MSP430 device interrogates the fuel gauge for voltage, current, and other parameters via SMBus. It then adjusts the p - U-513 Using the bq2040, Smart Battery System Gas Gauge ICPDF, 131 Kb, Archivo publicado: sept 5, 1999
The bq2040 Gas Gauge IC meets the requirements for systems incorporating the industry standard Smart Battery System bus and data set. It is based on Unitrode's proven technology for accurately monitoring battery capacity.In this tutorial, the user is the battery system designer who determines the configuration of a pack, not the end-user of a system. Terms from the SMB/SBD specifications are
