IOUT_OC
CS2±
The ADC on this pin is averaged every 2.6 ms with 12-bit
accuracy for this fault. This information is compared with
the IOUT_OC_FAULT_LIMIT to set the flag.

IOUT_OC:
CS2_Range/212
IOUT_OC_
FAULT_RESPONSE
The ADC on this pin is averaged every 328 μs with 9-bit
accuracy for CC mode. This information is compared with
the IOUT_OC_FAULT_LIMIT ± the threshold set in Register
0xFE5D[2:0] to enter CC mode. For turbo mode, the
averaging is every 41 μs with an equivalent 6-bit
resolution.
CC mode:
CS2_Range/29
CC turbo mode:
CS2_Range/26
IOUT_OC_LV
CS2±
The ADC on this pin is averaged every 10.5 ms with 12-bit

IOUT_UC
CS2±
The ADC on this pin is averaged every 10.5 ms with 12-bit
accuracy for this fault. This information is compared with
IOUT_UC_FAULT_LIMIT to set the flag.
0xFE31[7:4]
IOUT_UC:
CS2_Range/212
IOUT_UC_FAULT_
RESPONSE
The ADC on this pin is averaged every 328 μs with 9-bit
accuracy for constant current mode. This information is
compared with the IOUT_UC_FAULT_LIMIT ± the threshold
set in Register 0xFE5D[2:0] to enter CC mode. For turbo
mode, the averaging is every 41 μs with an equivalent 6-bit
resolution.
