(2)
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.
(3)
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:
(5)
The default setting on the EVM is 3 Adc for adapter current regulation.
