  Operating Fuel Gauge bq20z7x/8x/9x and SMBus-Like bq24745/47/65 Chargers
  PDF, 132 Kb, Datei veröffentlicht: Oct 6, 2009
  The smart charger bq24747/765 is a high-efficiency, synchronous battery charger with an integrated input current comparator. This charger provides low component count for space constrained, multichemistry battery charging applications. SMBus input current, charge current, and input current digital-to-analog converters allow for very high regulation accuracies that the system power management micr

  Wide-Vin Battery-Charger Using SMBus MSP430 MCUs and bq Fuel Gauges (Rev. A)
  PDF, 1.0 Mb, Revision: A, Datei veröffentlicht: 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

  bq29330 External Short Circuit Protection
  PDF, 155 Kb, Datei veröffentlicht: Aug 22, 2007
  In Li-ion battery pack design, short-circuit protection should be given sufficient emphasis to ensure that even if an external pack short does occur, it is benign. Properly designed battery fuel gauge solutions using the bq29330 analog front-end (AFE) protector and bq20z70, bq20z75, bq20z90, and bq20z95 fuel gauge ICs not only safeguards the battery, but also ensures a full recovery of functionali

  Fast Cell Balancing Using External MOSFET (Rev. A)
  PDF, 153 Kb, Revision: A, Datei veröffentlicht: Jan 26, 2009
  The need for cell balancing comes from the fact that cell-to-cell differences in self-discharge, capacity, and impedance can lead to different charge states among the cells. However, the charger terminates the charge based on the summed voltage only, which may leave some cells undercharged and others overcharged. To remedy this imbalance and to achieve the goal of having all cells reaching 100% st
