Page 3: Bq26500Evm-Based Circuit Module
Circuit Module The bq26500EVM based circuit module is an example circuit for battery fuel gauging of a single cell Li- Ion/Li-Polymer battery pack. There are two separate circuits on the EVM module. One is the active bq26500 fuel gauging circuitry; the other is the logic and power control to program the on-chip configuration EEPROM of the bq26500. -

Loading the Sense Resistor Value The bq26500EVM comes with a 20-mΩ sense resistor on the circuit board. Make sure the sense resistor value is entered in the RS box at the top of the initial register screen. This value is used by the PC program to convert the bq26500 data set to engineering units. - Page 10 The bq26500 can be reset at anytime by using the Options|Special Options|Reset bq26500 from the pulldown menu. When reset, the bq26500 loads the configuration values from EEPROM and set the remaining capacity registers to zero. bq26500EVM Single-Cell Battery Fuel Gauge Evaluation Module SLUU174A – March 2006 – Revised October 2013 Submit Documentation Feedback...
