^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 653) This entry configures the overvoltage protection feature of bq24257-
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 654) type charger devices. This feature protects the device and other
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 655) components against damage from overvoltage on the input supply. See
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 656) device datasheet for details.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 668) This entry configures the input dynamic power path management voltage of
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 669) bq24257-type charger devices. Once the supply drops to the configured
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 670) voltage, the input current limit is reduced down to prevent the further
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 671) drop of the supply. When the IC enters this mode, the charge current is
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 672) lower than the set value. See device datasheet for details.
