Fast OVP threshold
R/W
These bits set the threshold for the fast OVP analog comparator. This threshold is programmable
from 0.8 V to 1.6 V. Setting this value to 0x00 corresponds to a 0.8 V threshold. Setting this value to
0x3F corresponds to a 1.6 V threshold. Each LSB increments the threshold by 12.5 mV. The fast OVP
threshold can be set using the following formula:
Fast_OVP_Threshold = ( Bits[5:0] × 0.8 V/63) + 0.8 V

Description
1 = negative gain is introduced.
0 = positive gain is introduced.

VS1 trim
R/W
These bits set the amount of gain trim that is applied to the VS1 ADC reading. This register trims
the voltage at the VS1 pin for external resistor tolerances. When there is 1 V on the VS1 pin, this
register is trimmed until the VS1 voltage value (Register 0x15[15:4]) reads 2560 (0xA00).

VS2 trim
R/W
These bits set the amount of gain trim that is applied to the VS2 ADC reading. This register trims
the voltage at the VS2 pin for external resistor tolerances. When there is 1 V on the VS2 pin, this
register is trimmed until the VS2 voltage value (Register 0x16[15:4]) reads 2560 (0xA00).

VS3 trim
R/W
These bits set the amount of gain trim that is applied to the VS3 ADC reading. This register trims
the voltage at the VS3 pins for external resistor tolerances. When there is 1 V on each VS3 pin, this
register is trimmed until the VS3 voltage value (Register 0x17[15:4]) reads 2560 (0xA00). The VS3
trim must be performed before the load OVP and load UVP trims are performed.
