Summary of Supported Commands PMBus COMMAND NAME, OR FEATURE CMD CODE (REGISTER) COMMAND OR FEATURE DESCRIPTION LTM4686B NVM FACTORY-DEFAULT VALUE AND/OR ATTRIBUTES PAGE MFR_ TEMPERATURE_1_ PEAKn 0xDF Maximum value of TSNSna measured temperature since the last MFR_CLEAR_PEAKS. Default value not applicable, read-only, paged, not stored in NVM. 118 MFR_CLEAR_PEAKS 0xE3 Clears all peak values. Default value not applicable, send byte only, non-paged, not stored in NVM. 110 MFR_PADS 0xE5 Digital status of the I/O pads. Default value not applicable, read-only, non-paged, not stored in NVM. 114 MFR_ADDRESS 0xE6 LTM4686B’s I2C slave address, right-justified. 0x4F, read/write, non-paged, stored in user-editable NVM. Bits[6:4] represent the user-configurable upper 3 bits of the 7-bit slave address of the device. Bits[3:0] are dictated by the ASEL resistor pin-strap setting. Setting this command to 0x80 disables device-specific addressing. 84 MFR_SPECIAL_ID 0xE7 Manufacturer code representing IC silicon and revision 0x477X, read-only, non-paged. 109 MFR_IIN_OFFSETn 0xE9 Coefficient used in calculations of READ_IIN and MFR_READ_IINn, representing the contribution of input current drawn by the control IC, including the MOSFET drivers. 0x9315 (0.04816A), read/write, paged, stored in user-editable NVM. 92 MFR_FAULT_LOG_ STORE 0xEA Commands a transfer of the fault log from RAM to EEPROM. This causes the part to behave as if a channel has faulted off. Default value not applicable, send byte only, non-paged, not stored in NVM. 126 MFR_FAULT_LOG_ CLEAR 0xEC Initialize the EEPROM block reserved for fault logging and clear any previous fault logging locks. Default value not applicable, send byte only, non-paged, not stored in NVM. 126 MFR_READ_IINn 0xED Calculated input current, by channel. Default value not applicable, read-only, paged, not stored in NVM. 117 MFR_FAULT_LOG 0xEE Fault log data bytes. This sequentially retrieved data is used to assemble a complete fault log. Default value not applicable, read-only, non-paged, stored in fault-log NVM. 125 MFR_COMMON 0xEF Manufacturer status bits that are common across multiple ADI PSM ICs/modules. Default value not applicable, read-only, non-paged, not stored in NVM. 114 MFR_COMPARE_ USER_ALL 0xF0 Compares current command contents (RAM) with NVM. Default value not applicable, send byte only, non-paged, not stored in NVM. 121 MFR_ TEMPERATURE_2_ PEAK 0xF4 Maximum measured control IC junction temperature since last MFR_CLEAR_PEAKS. Default value not applicable, read-only, non-paged, not stored in NVM. 118 MFR_PWM_ CONFIG_* 0xF5 Configuration bits for setting the phase interleaving angles of Channels 0 and 1, SHARE_CLK behavior in UVLO, and using the fully differential amplifier to regulate paralleled output channels. 0x10, read/write, non-paged, stored in user-editable NVM. When bit 7 is 0b, Channel 1’s output is regulated by the VOSNS1 and SGND feedback signals. When bit 7 is 1b, Channel 1’s output is regulated by the VOSNS0+ and VOSNS0– feedback signals. Only set bit 7 to 1b for PolyPhase rail applications. The command is named MFR_PWM_CONFIG and referred to as MFR_PWM_CONFIG_LTM468X in LTpowerPlay. 88 MFR_IOUT_CAL_ GAIN_TCn 0xF6 Temperature coefficient of the current sensing element. 0x0F14 (3860ppm/°C), read/write, paged, stored in user-editable NVM. 93 MFR_TEMP_1_GAINn 0xF8 Sets the slope of the temperature sensors that interface to TSNSna. 0x3FAE (0.995, in custom units), read/write, paged, stored in user-editable NVM. 95 |
