A)PDF, 1.0 Mb, Revision: A, File published: 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, File published: Sep 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.
