Bugfix set date (year):
In the previous version the year selection was clipped to a range between 16 and 22. To avoid clipping issues in future the clipping is now done based on the firmware release date as lower limit and release date +10 years as upper limit.

15 The bq5105x provides one status output, CHG. This output is an open-drain NMOS device that is rated to 20 V. | |
16 The open-drain FET connected to the CHG pin will be turned on whenever the output (BAT) of the charger is | |
17 enabled. As a note, the output of the charger supply will not be enabled if the VRECT-REG does not converge to the | |
18 no-load target voltage. | |
19 | |
644 | 20 CHG F4 7 O Open-drain output � active when BAT is enabled. Float if not used. |
