112 / 130 page ![]() LTM4686B 112 Rev. 0 For more information www.analog.com APPENDIX C: PMBUS COMMAND DETAILS STATUS_VOUT The STATUS_VOUT command returns one byte of VOUT status information. STATUS_VOUT Message Contents: BIT MEANING 7 VOUT overvoltage fault. 6 VOUT overvoltage warning. 5 VOUT undervoltage warning. 4 VOUT undervoltage fault. 3 VOUT_MAX warning. 2 TON_MAX fault. 1 TOFF_MAX warning. 0 Not supported by the LTM4686B (returns 0). ALERT can be asserted if any of bits[7:1] are set. These may be cleared by writing a 1 to their bit position in STATUS_VOUT, in lieu of a CLEAR_FAULTS command. This command has one data byte. STATUS_IOUT The STATUS_IOUT command returns one byte of IOUT status information. STATUS_IOUT Message Contents: BIT MEANING 7 IOUT overcurrent fault. 6 Not supported (LTM4686B returns 0). 5 IOUT overcurrent warning. 4:0 Not supported (LTM4686B returns 0). ALERT can be asserted if any supported bits are set. Any supported bit may be cleared by writing a 1 to that bit position in STATUS_IOUT, in lieu of a CLEAR_FAULTS command. This command has one data byte. STATUS_INPUT The STATUS_INPUT command returns one byte of VIN (SVIN) status information. STATUS_INPUT Message Contents: BIT MEANING 7 SVIN overvoltage fault. 6 Not supported (LTM4686B returns 0). 5 SVIN undervoltage warning. 4 Not supported (LTM4686B returns 0). 3 Unit off for insufficient SVIN voltage. 2 Not supported (LTM4686B returns 0). 1 Input over current warning. 0 Not supported (LTM4686B returns 0) ALERT can be asserted if bit 7 is set. Bit 7 may be cleared by writing it to a 1, in lieu of a CLEAR_FAULTS command. |
