88 / 128 page  LTC3884/LTC3884-1 88 3884fe For more information www.linear.com/LTC3884 PMBus COMMAND DETAILS TEMPERATURE External Temperature Calibration COMMAND NAME CMD CODE DESCRIPTION TYPE PAGED DATA FORMAT UNITS NVM DEFAULT VALUE MFR_TEMP_1_GAIN 0xF8 Sets the slope of the external temperature sensor. R/W Word Y CF Y 1.0 0x4000 MFR_TEMP_1_OFFSET 0xF9 Sets the offset of the external temperature sensor. R/W Word Y L11 C Y 0.0 0x8000 MFR_TEMP_1_GAIN The MFR_TEMP_1_GAIN command will modify the slope of the external temperature sensor to account for non-idealities in the element and errors associated with the remote sensing of the temperature in the inductor. This command has two data bytes and is formatted in 16-bit 2’s complement integer. The effective gain adjustment is N • 2–14. The nominal value is 1. MFR_TEMP_1_OFFSET The MFR_TEMP_1_OFFSET command will modify the offset of the external temperature sensor to account for non- idealities in the element and errors associated with the remote sensing of the temperature in the inductor. This command has two data bytes and is formatted in Linear_5s_11s format. External Temperature Limits COMMAND NAME CMD CODE DESCRIPTION TYPE PAGED DATA FORMAT UNITS NVM DEFAULT VALUE OT_FAULT_LIMIT 0x4F External overtemperature fault limit. R/W Word Y L11 C Y 100.0 0xEB20 OT_WARN_LIMIT 0x51 External overtemperature warning limit. R/W Word Y L11 C Y 85.0 0xEAA8 UT_FAULT_LIMIT 0x53 External undertemperature fault limit. R/W Word Y L11 C Y –40.0 0xE580 OT_FAULT_LIMIT The OT_FAULT_LIMIT command sets the value of the external sense temperature measured by the ADC, in degrees Celsius, which causes an overtemperature fault. The READ_TEMPERATURE_1 value will be used to determine if this limit has been exceeded. This command has two data bytes and is formatted in Linear_5s_11s format. OT_WARN_LIMIT The OT_WARN_LIMIT command sets the value of the external sense temperature measured by the ADC, in degrees Celsius, which causes an overtemperature warning. The READ_TEMPERATURE_1 value will be used to determine if this limit has been exceeded. |
