Measures charge flow using a V-to-F converter with offset of less than 16 

μV after 

calibration  
 

The Texas Instruments bq2060A SBS-compliant Gas Gauge IC* for the battery pack maintains 
an accurate record of the available charge. It determines battery capacity by monitoring the 
amount of charge input or removed from the smart battery.  

The bq2060A measures battery voltage, temperature, and current estimates battery self-
discharge, and monitors the battery for low-voltage thresholds. It measures charge and 
discharge activity by monitoring the voltage across a small-value series sense resistor between 
the battery’s negative terminal and the negative terminal of the battery pack. The available 
battery charge is determined by monitoring this voltage and correcting the measurement for 
environmental and operating conditions.  

For more information about the Texas Instruments bq2060A SBS-compliant Gas Gauge IC*, 
see the manufacturer website.
