The VOUT_MIN command sets a lower limit on the output voltage the unit can command regardless of any other commands or combinations. The intent of this command is to provide a safeguard against a user accidentally setting the output voltage to a level which will render the load inoperable.

During power conversion, any output voltage change (including VOUT_COMMAND, VOUT_TRIM, margin operations) that causes the new target voltage to be less than the current value of VOUT_MIN will cause the VOUT_MAX_MIN_WARNING fault condition. These results cause the TPSM8S6C24 to:
Although the scenario is uncommon, note that the same response results if the user attempted to program VOUT_MAX greater than the current output voltage target.
Data Validity
The minimum and maximum valid data values for VOUT_MIN follow those of VOUT_MAX. Attempts to write (2Bh) VOUT_MIN to any value outside those specified as valid will be considered invalid/unsupported data and cause the TPSM8S6C24 to respond by flagging the appropriate status bits and notifying the host according to the PMBus 1.3.1 Part II specification section 10.9.3.
