Some customers are unfamiliar with battery monitors or gas gauges for their handheld portable applications. The intent of this application report is to provide information about TI product families that are excellent options when selecting a battery gas gauge solution. - HDQ Compatibility Between OMAP and BQ ProductsPDF, 76 Kb, Archivo publicado: jun 17, 2004
TI OMAP? and battery management products are found in today's fast-paced developing market of handheld products that include cellular phones with integrated camera and video recorder features, PDAs with wireless capabilities, and advanced handheld gaming systems. In many of these systems, both OMAP and battery management products coexist. OMAP platforms have an HDQ engine that is used to communica - Gas Gauging Basics Using TI Battery Monitor ICs (Rev. A)PDF, 252 Kb, Revisión: A, Archivo publicado: oct 17, 2003
To solve the challenges of precise capacity tracking and monitoring, Texas Instruments has developed a family of accurate battery monitor devices. These devices use the coulomb counting method in order to provide the user with accurate and reliable information about the battery?s state of charge. The purpose of this report is to provide the basics of building an accurate gas-gauging feature using - HDQ Communication Basics (Rev. A)PDF, 103 Kb, Revisión: A, Archivo publicado: sept 18, 2008
This report compares the communication timing specifications for the different battery gas gauge and battery monitor products. It discusses some of the interface requirements necessary for robust HDQ communication, such as the need for a break prior to each communication, how to reliably read 16-bit dynamic values over the 8-bit bus, and the need for some noise filtering on the HDQ line. It also
