Published Date: 10/30/2007


This application report provides the basic operating theory and key design considerations for the bq27500 and bq27501 single-cell Li-ion fuel gauge ICs with the Impedance Track™ algorithm. The bq27500/501 ICs are designed to reside on the system's main board in applications with an embedded or removable battery pack. To achieve best results the fuel gauge ICs must work properly with the ba
