  Multicell Li-Ion and Li-Pol Battery Gas-Gauge Application Using bq26500
  PDF, 185 Kb, File published: Jan 29, 2004
  The bq26500 is the first complete battery fuel gauge for handheld devices such as PDAs and cellular handsets. Many of these applications use only one Li-Ion or Li-Polymer cell in the battery, producing a nominal 3.6 V. Although optimized for single-cell applications, the bq26500 works well in systems using multicell battery packs, particularly two series-cell batteries producing 7.2 V. This applic

  HDQ Communication Basics (Rev. A)
  PDF, 103 Kb, Revision: A, File published: Sep 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

  ESD and RF Mitigation in Handheld Battery Pack Electronics
  PDF, 68 Kb, File published: Mar 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
