82 / 84 page  ADP1047/ADP1048 Data Sheet Rev. 0 | Page 82 of 84 Table 164. Register 0xFE99—Debug Flag 3 Bits Bit Name R/W Description 7 VIN_OV_FAULT R 1 = input voltage on VAC is larger than the value in VIN_OV_FAULT_LIMIT (Register 0x55). 6 VCORE_OV R 1 = an overvoltage condition is present on the VCORE rail. 5 PIN_OP_WARN R 1 = input overpower warning. 4 AC_PERIOD R 1 = controller is not able to detect the ac line period; the maximum value of the period is used and this flag is set. 3 IIN_OC_WARN R 1 = input current measured on the CS ADC is larger than the value in IIN_OC_WARN_LIMIT (Register 0x5D). 2 IIN_OC_FAULT R 1 = input current measured on the CS ADC is larger than the value in IIN_OC_FAULT_LIMIT (Register 0x5B). 1 FAST_OCP R 1 = the threshold set for the comparator on the ILIM pin has been crossed. 0 INPUT R 1 = input voltage, input current, or input power fault or warning. Table 165. Register 0xFE9A—Debug Flag 4 Bits Bit Name R/W Description 7 OLP R 1 = one of the two voltage dividers is probably disconnected or malfunctioning. 6 FAST_OVP R 1 = the threshold set for the comparator on the OVP pin has been crossed. 5 VOUT_UV_FAULT R 1 = output voltage is below the VOUT_UV_FAULT_LIMIT (Register 0x44). 4 VOUT_UV_WARN R 1 = output voltage is below the VOUT_UV_WARN_LIMIT (Register 0x43). 3 VOUT_OV_WARN R 1 = output voltage is above the VOUT_OV_WARN_LIMIT (Register 0x42). 2 VOUT_OV_FAULT R 1 = output voltage is above the VOUT_OV_FAULT_LIMIT (Register 0x40). 1 VOUT_OV R General output overvoltage fault: this flag is a combination (OR) of any output overvoltage flag (Register 0x7A, Bit 7 and Register 0xFE80, Bit 4 (FAST_OVP)). 0 VOUT R 1 = any fault on output voltage (overvoltage, undervoltage, fast OVP, or accurate OVP). Table 166. Register 0xFE9B—Debug Flag 5 Bits Bit Name R/W Description [7:3] RSVD R Reserved. 2 LOW_POWER R 1 = input power has dropped below the threshold for low power mode operation. 1 VDD_3.3V_UV R 1 = an undervoltage condition is present on the VDD rail. 0 INRUSH R 1 = INRUSH control relay is off. |
