52 / 88 page  ADP1046A Data Sheet Rev. 0 | Page 52 of 88 Table 18. Register 0x12—HF ADC Reading Bits Bit Name R/W Description [7:0] HF ADC reading R This register contains the reading from the high frequency ADC. Table 19. Register 0x13—CS1 Value (Input Current) Bits Bit Name R/W Description [15:4] Input current value R 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). [3:0] Reserved R Reserved. Table 20. Register 0x14—ACSNS Value Bits Bit Name R/W Description [15:4] ACSNS voltage value R This register contains the 12-bit ACSNS slow ADC voltage information. [3:0] Reserved R Reserved. Table 21. Register 0x15—VS1 Voltage Value Bits Bit Name R/W Description [15:4] VS1 voltage value R 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). [3:0] Reserved R Reserved. Table 22. Register 0x16—VS2 Voltage Value Bits Bit Name R/W Description [15:4] VS2 voltage value R 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). [3:0] Reserved R Reserved. Table 23. Register 0x17—VS3 Voltage Value (Output Voltage) Bits Bit Name R/W Description [15:4] VS3 voltage value R 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). [3:0] Reserved R Reserved. |
