64 / 93 page  Data Sheet ADP1050 STATUS_BYTE Table 50. Register 0x78—STATUS_BYTE Bits Bit Name/Function R/W Description 7 Reserved R Reserved. 6 POWER_OFF R This bit is asserted if the device is not providing power to the output, regardless of the reason, including simply not being enabled. 5 VOUT_OV_FAULT R An output overvoltage fault has occurred. 4 Reserved R Reserved. 3 VIN_UV_FAULT R An input undervoltage fault has occurred. 2 TEMPERATURE R A temperature fault or warning has occurred. 1 CML R A communications, memory, or logic fault has occurred. 0 NONE OF THE ABOVE R A fault or warning not listed in Bits[7:1] has occurred. STATUS_WORD Table 51. Register 0x79—STATUS_WORD Bits Bit Name/Function R/W Description 15 VOUT R Any bit asserted in STATUS_VOUT asserts this bit. 14 Reserved R Reserved. 13 INPUT R Any bit asserted in STATUS_INPUT asserts this bit. 12 Reserved R Reserved. 11 POWER_GOOD R POWER_GOOD is a negation of POWER_GOOD, which means that the output power is not good. This bit is set when the sensed VOUT is less than the limit programmed in the POWER_GOOD_OFF command. This bit is cleared when the sensed VOUT voltage is greater than the limit that is programmed in the POWER_GOOD_ON command. This flag also triggers the PGOOD flag in Register 0xFEA0[6]. [10:7] Reserved R Reserved. 6 POWER_OFF R This bit is asserted if the device is not providing power to the output, regardless of the reason, including not being enabled. 5 VOUT_OV_FAULT R An output overvoltage fault has occurred. 4 Reserved R Reserved. 3 VIN_UV_FAULT R An input undervoltage fault has occurred. 2 TEMPERATURE R An overtemperature fault or warning has occurred. 1 CML R A communications, memory, or logic fault has occurred. 0 NONE OF THE ABOVE R A fault or warning not listed in Bits[7:1] has occurred. STATUS_VOUT Table 52. Register 0x7A—STATUS_VOUT Bits Bit Name/Function R/W Description 7 VOUT_OV_FAULT R An output overvoltage fault has occurred. [6:5] Reserved R Reserved. 4 VOUT_UV_FAULT R An output undervoltage fault has occurred. 3 VOUT_MAX warning An attempt was made to set the output voltage to a value greater than allowed by theVOUT_MAX command. [2:0] Reserved R Reserved. STATUS_INPUT Table 53. Register 0x7C—STATUS_INPUT Bits Bit Name/Function R/W Description [7:5] Reserved R Reserved. 4 VIN_UV_FAULT R An input undervoltage fault has occurred. 3 VIN_LOW R The unit is off due to insufficient input voltage. 2 IIN_OC_FAST_FAULT R An input overcurrent fast fault has occurred. [1:0] Reserved R Reserved. Rev. A | Page 63 of 92 |
