116 / 130 page ![]() LTM4686B 116 Rev. 0 For more information www.analog.com APPENDIX C: PMBUS COMMAND DETAILS MFR_INFO The MFR_INFO command contains additional status bits that are LTM4686B-specific and may be common to multiple ADI PSM products. MFR_INFO Data Contents BIT MEANING 15:6 Reserved. 5 EEPROM ECC status. 0: Corrections have been made in the EEPROM user space. 1: No corrections have been made in the EEPROM user space. 4:0 Reserved EEPROM ECC status is updated after each RESTORE_USER_ALL or RESET command, a power-on reset or an EEPROM bulk read operation. This read-only command has two data bytes. TELEMETRY COMMAND NAME CMD CODE DESCRIPTION TYPE PAGED FORMAT UNITS NVM DEFAULT VALUE READ_VIN 0x88 Measured input supply (SVIN) voltage. R Word N L11 V NA READ_VOUT 0x8B Measured output voltage. R Word Y L16 V NA READ_IIN 0x89 Calculated input supply current. R Word N L11 A NA MFR_READ_IIN 0xED Calculated input current per channel. R Word Y L11 A NA READ_IOUT 0x8C Measured output current. R Word Y L11 A NA READ_TEMPERATURE_1 0x8D Power stage temperature sensor. This is the value used for all temperature related processing, including IOUT_CAL_GAIN. R Word Y L11 C NA READ_TEMPERATURE_2 0x8E Control IC die temperature. Does not affect any other registers. R Word N L11 C NA READ_DUTY_CYCLE 0x94 Duty cycle of the top gate control signal. R Word Y L11 % NA READ_POUT 0x96 Calculated output power. R Word Y L11 W NA MFR_VOUT_PEAK 0xDD Maximum measured value of READ_VOUT since last MFR_CLEAR_PEAKS. R Word Y L16 V NA MFR_VIN_PEAK 0xDE Maximum measured value of READ_VIN since last MFR_CLEAR_PEAKS. R Word N L11 V NA MFR_TEMPERATURE_1_PEAK 0xDF Maximum measured value of power stage temperature (READ_TEMPERATURE_1) since last MFR_CLEAR_PEAKS. R Word Y L11 C NA MFR_TEMPERATURE_2_PEAK 0xF4 Maximum measured value of control IC die temperature (READ_TEMPERATURE_2) since last MFR_CLEAR_PEAKS. R Word N L11 C NA MFR_IOUT_PEAK 0xD7 Report the maximum measured value of READ_IOUT since last MFR_CLEAR_PEAKS. R Word Y L11 A NA MFR_ADC_CONTROL 0xD8 ADC telemetry parameter selected for repeated fast ADC read back. R/W Byte N Reg 0x00 MFR_ADC_TELEMETRY_ STATUS 0xDA ADC telemetry status indicating which parameter is most recently converted when the short round robin ADC loop is enabled R/W Byte N Reg NA |
