72 / 113 page  ADP1052 Data Sheet Rev. B | Page 72 of 113 Table 53. Register 0x61—TON_RISE Bits Bit Name/Function R/W Description [15:11] Exponent R/W 5-bit, twos complement N value for linear format, X = Y × 2N. [10:0] Mantissa R/W 11-bit, twos complement Y value for linear format, X = Y × 2N. TOFF_DELAY The TOFF_DELAY command sets the turn-off delay time in milliseconds (ms). The ADP1052 supports only those values listed in Table 54. Table 54. Register 0x64—TOFF_DELAY (Turn-Off Delay Options Supported in the ADP1052) Register Setting Turn-Off Delay Time (ms) 0000000000000000 (0x0000) 0 0000000000110010 (0x0032) 50 0000000011111010 (0x00FA) 250 0000001111101000 (0x03E8) 1000 Table 55. Register 0x64—TOFF_DELAY Bits Bit Name/Function R/W Description [15:11] Exponent R/W 5-bit, twos complement, N value for linear format X = Y × 2N. [10:0] Mantissa R/W 11-bit, twos complement, Y value for linear format X = Y × 2N. STATUS_BYTE Table 56. Register 0x78—STATUS_BYTE Bits Bit Name/Function R/W Description 7 Reserved R Reserved. 6 POWER_OFF R This bit is asserted when the unit 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 IOUT_OC_FAULT R An output overcurrent fault has occurred. 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 57. Register 0x79—STATUS_WORD Bits Bit Name/Function R/W Description 15 VOUT R Any bit asserted in STATUS_VOUT asserts this bit. 14 IOUT R Any bit asserted in STATUS_IOUT asserts this bit. 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 clears 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 unit 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 IOUT_OC_FAULT R An output overcurrent fault has occurred. 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. |
