92 / 93 page  Data Sheet ADP1050 MANUFACTURER SPECIFIC VALUE READING REGISTERS Table 166. Register 0xFEA7—CS1 Value Bits Bit Name/Function R/W Description [15:4] CS1 current value R This register contains 12-bit CS1 current information. The range of the CS1 input pin is from 0 V to 1.6 V. Each LSB corresponds to 390.625 μV. At 0 V input, the value in this register is 0 decimal. The nominal voltage at the CS1 pin is 1 V. At 1 V input, the value of these bits is 0xA00 (2560 decimal). The reading is equivalent to the READ_IIN command. [3:0] Reserved R Reserved. Table 167. Register 0xFEA9—CS3 Value Bits Bit Name/Function Type Description [15:4] CS3 voltage value R This register contains 12-bit CS3 current information calculated by using the CS1 reading and duty cycle information. Each LSB corresponds to 4× the CS1 LSB in Register 0xFEA7, multiplied by the turns ratio of the main transformer, n (n = NPRI/NSEC). [3:0] Reserved R Reserved. Table 168. Register 0xFEAA—VS Value Bits Bit Name/Function R/W Description [15:4] VS voltage value R This register contains the 12-bit VS± output voltage information. The range of the VS± input pins is from 0 V to 1.6 V. Each LSB corresponds to 390.625 μV. At 0 V input, the value in this register is 0. The nominal voltage at the VS+ and VS− pins is 1 V. At 1 V input, the value of these bits is 0xA00 (2560 decimal). The reading is equivalent to the READ_VOUT command. [3:0] Reserved R Reserved. Table 169. Register 0xFEAB—RTD Value Bits Bit Name/Function R/W Description [15:4] RTD temperature value R These bits contain the 12-bit RTD temperature information, as determined from the RTD pin. The range of the RTD input pin is from 0 V to 1.6 V. Each LSB corresponds to 390.625 μV. At 0 V input, the value in this register is 0. The nominal voltage at the RTD pin is 1 V. At 1 V input, the value of these bits is 0xA00 (2560 decimal). [3:0] Reserved R Reserved. Table 170. Register 0xFEAC—VF Value Bits Bit Name/Function R/W Description [15:5] VF voltage value R This register contains the 11-bit VF voltage information. The range of the VF input pin is from 0 V to 1.6 V. Each LSB corresponds to 781.25 μV. At 0 V input, the value in this register is 0. The nominal voltage at the VF pin is 1 V. At 1 V input, the value of these bits is 0x500 (1280 decimal). The reading is equivalent to the READ_VIN command. [4:0] Reserved R Reserved. Table 171. Register 0xFEAD—Duty Cycle Value Bits Bit Name/Function R/W Description [15:12] Reserved R Reserved. [11:0] Duty cycle value R This register contains the 12-bit duty cycle information. Each LSB corresponds to 0.0244% duty cycle. At 100% duty cycle, the value of these bits is 0xFFF (4095 decimal). Table 172. Register 0xFEAE—Input Power Value Bits Bit Name/Function R/W Description [15:0] Input power value R This register contains the 16-bit input power information. This value is the product of the input voltage value (VF) and input current value (CS1). The product of two 12-bit values is a 24-bit value, and the eight LSBs are discarded. Rev. A | Page 91 of 92 |
