The default setting is 2 Adc for fast-charge current and 0.2 Adc for precharge current.
In the bq24133, once the voltage on OVPSET is above the 1.6-V ACOV threshold or below the 0.5-V
ACUV threshold, the charge is disabled, and the battery is switched to the system instead of the adapter.
ACUV threshold, the charge is disabled, and the battery is switched to the system instead of the adapter.

For Note 001, ACUV = 2.51 V; for Note 002, ACUV = 5.87 V.
(4)
For Note 001, ACOV = 8.03 V; for Note 002, ACOV = 18.80 V.
Similar to setting battery regulation current, the adapter current is set by the voltage on ACSET pin using
the following equation:
