    Download BQ2416xSW.zip from the charger's product folder, unzip the file, and double-click on the SETUP.EXE file. Follow the installation steps. Because the bq24160, bq24161, and bq24163 have the watchdog timers enabled, it is recommended that you set the software's Reset Watchdog Timer to reset every 5 seconds. Otherwise, after 30 seconds of operation, the IC enters Default mode.
