- ESD and RF Mitigation in Handheld Battery Pack ElectronicsPDF, 68 Kb, Archivo publicado: marzo 6, 2008
It is imperative to protect the electronics in a consumer-removable battery pack from ESD damage. Even an upset without permanent damage may be unacceptable to the end-user. Handheld equipment that contains a transmitter also may require protection to guard against improper measurement and/or upset due to the affect of the radio frequency (RF) on the circuitry. Because the RF field strength varies - Going to Production With the bq2754x (Rev. A)PDF, 581 Kb, Revisión: A, Archivo publicado: marzo 11, 2011
This application report presents a strategy for high speed, economical calibration, and production programming of the bq2754x single-cell gas gauge. Flowchart examples are provided, along with step-by-step instructions for preparing a calibration data set that is required when creating the golden data flash image (DFI) that is programmed into all bq2754x at the pack maker production line. - bq27541 to bq27541-v200 Change ListPDF, 40 Kb, Archivo publicado: feb 17, 2010

The bq275xx gas gauge integrated circuits (IC) can use an I2C line for communication with the host system. It is necessary to allow application-layer software on the host system to access parameters made available by the gas gauge IC. Multiple levels of abstraction are between the gauge and a given application. This document describes an example implementation of each of these layers in an effo - How to Transfer bq27541 Into Hibernate ModePDF, 42 Kb, Archivo publicado: abr 13, 2010
