55 / 84 page  Data Sheet ADP1047/ADP1048 Rev. 0 | Page 55 of 84 STATUS_VOUT REGISTER A value of 1 in this register indicates that a fault has occurred. Table 45. Register 0x7A—STATUS_VOUT Bits Bit Name R/W Description 7 VOUT_OV_FAULT R 1 = output overvoltage fault. 6 VOUT_OV_WARN R 1 = output overvoltage warning. 5 VOUT_UV_WARN R 1 = output undervoltage warning. 4 VOUT_UV_FAULT R 1 = output undervoltage fault. STATUS_INPUT REGISTER A value of 1 in this register indicates that a fault has occurred. Table 46. Register 0x7C—STATUS_INPUT Bits Bit Name R/W Description 7 VIN_OV_FAULT R 1 = input overvoltage fault. 5 VIN_UV_WARN R 1 = input undervoltage warning. 4 VIN_UV_FAULT R 1 = input undervoltage fault. 3 VIN_LOW R 1 = device is off due to insufficient input voltage; that is, input voltage is below the turn-off threshold. 2 IIN_OC_FAULT R 1 = input overcurrent fault. 1 IIN_OC_WARN R 1 = input overcurrent warning. 0 PIN_OP_WARN R 1 = input overpower warning. STATUS_TEMPERATURE REGISTER A value of 1 in this register indicates that a fault has occurred. Table 47. Register 0x7D—STATUS_TEMPERATURE Bits Bit Name R/W Description 7 OT_FAULT R 1 = overtemperature fault. 6 OT_WARN R 1 = overtemperature warning. [5:0] RSVD R Reserved. READ_VIN REGISTER This register returns the input voltage (V) in VIN linear mode format (X = Y × 2N). Table 48. Register 0x88—READ_VIN Bits Bit Name R/W Description [15:11] Exponent R Return the exponent (N) used in VIN linear mode format (X = Y × 2N). The exponent is set in the exponent register (Register 0xFE39, Bits[5:3]). [10:8] High bits R Mantissa high bits (Y[10:8]) used in VIN linear mode format (X = Y × 2N). [7:0] Low byte R Mantissa low byte (Y[7:0]) used in VIN linear mode format (X = Y × 2N). The exponent (N) is set in the exponent register (Register 0xFE39, Bits[5:3]). READ_IIN REGISTER This register returns the input current (A) in current linear mode format (X = Y × 2N). Table 49. Register 0x89—READ_IIN Bits Bit Name R/W Description [15:11] Exponent R Return the exponent (N) used in current linear mode format (X = Y × 2N). The exponent is set in the exponent register (Register 0xFE39, Bits[10:6]). [10:8] High bits R Mantissa high bits (Y[10:8]) used in current linear mode format (X = Y × 2N). [7:0] Low byte R Mantissa low byte (Y[7:0]) used in current linear mode format (X = Y × 2N). |
