Description
This register contains the reading from the high frequency ADC.
Description
This register contains the 12-bit input current information. This value is derived from a voltage
measurement at the CS1 input. To read the input current information, this register must be read
using two consecutive read operations. The eight bits of the first read return the eight MSBs of the
input current information. The top four bits of the second read return the four LSBs of the input
current information. The range of the CS1 input pin is from 0 V to 1.4 V. This value has 12 bits of
resolution, which results in an LSB size of 342 μV. At 0 V input, the value in this register is 0 (0x000).
At 1 V input, the value in this register is 2926 (0xB6E).

Description
This register contains the 12-bit ACSNS slow ADC voltage information.

Description
This register contains the 12-bit local output voltage information. This voltage is measured at the
VS1 pin. To read the VS1 voltage information, this register must be read using two consecutive
read operations. The eight bits of the first read return the eight MSBs of the local output voltage
information. The top four bits of the second read return the four LSBs of the local output voltage
information. The range of the VS1 input pin is from 0 V to 1.6 V. This value has 12 bits of resolution,
which results in an LSB size of 390.625 μV. At 0 V input, the value in this register is 0 (0x000). The
recommended nominal voltage at this pin is 1 V. At 1 V input, these bits read 2560 (0xA00).

Description
This register contains the 12-bit load output voltage information. This voltage is measured at the
VS2 pin. To read the load VS2 voltage information, this register must be read using two consecutive
read operations. The eight bits of the first read return the eight MSBs of the load output voltage
information. The top four bits of the second read return the four LSBs of the load output voltage
information. The range of the VS2 input pin is from 0 V to 1.6 V. This value has 12 bits of resolution,
which results in an LSB size of 390.625 μV. At 0 V input, the value in this register is 0 (0x000). The
recommended nominal voltage at this pin is 1 V. At 1 V input, these bits read 2560 (0xA00).
Reserved.
Description
This register contains the 12-bit remote output voltage information. This value is the differential
voltage between the VS3+ and VS3− pins. To read the remote output voltage information, this
register must be read using two consecutive read operations. The eight bits of the first read return
the eight MSBs of the remote output voltage information. The top four bits of the second read return
the four LSBs of the remote output voltage information. The range of the VS3± input pins is from
0 V to 1.6 V. This value has 12 bits of resolution, which results in an LSB size of 390.625 μV. At 0 V
input, the value in this register is 0 (0x000). The recommended nominal voltage at this pin is 1 V.
At 1 V input, these bits read 2560 (0xA00).
