  Configuring the bq27010/210 for Gas Gauge Applications
  PDF, 252 Kb, File published: Feb 23, 2007
  Accurate performance of the bq27x10 gas gauge requires that the 10 user-configurable EEPROM coefficients be programmed to values that reflect the appropriate host system and battery characteristics. This application report provides the basis for determining the optimal EEPROM coefficients from the host system operational characteristics and battery characterization data. Appendix A specifically ad

  Using the bq27x00 With a Primary Cell Battery
  PDF, 42 Kb, File published: Dec 15, 2005
  The bq27x00 is an accurate coulomb counter and contains algorithms to dynamically compensate the available capacity for temperature and discharge rate. If direct drive from the gauge to an LED display is not required, the bq27x00 can be used as an accurate gas gauge solution for a primary cell battery. Although the bq27x00 was designed for a single-cell rechargeable lithium-ion or lithium-polymer

  Multicell Li-Ion and Li-Pol Battery Gas-Gauge Application Using the bqJunior
  PDF, 58 Kb, File published: May 26, 2006
  The bqJuniorв„ў series of gas gauges are designed to operate from a single-cell, lithium-ion or lithium-polymer battery. Many applications that could benefit from using these gas gauges use two or more lithium cells in series, where the battery voltage exceeds the operating voltage for the bqJuniorв„ў gas gauges. This application report describes a low-component count solution for using th

  Building a Superior Battery Monitor with the bq27x00
  PDF, 43 Kb, File published: Jun 20, 2005
  The bq27x00 is a complete gas gauge solution for lithium-ion and lithium-polymer batteries. The bq27x00 also has internal registers and control commands that enable the host to use it as a battery monitor. A battery gas gauge solution can be built one of two ways: ignore all algorithms built into the bq27x00 and use the primitive functions to build a fully customized solution, or use some of the h

  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
