8.6.26 (2Bh) VOUT_MIN

CMD Address	2Bh
Write Transaction:	Write Word
Read Transaction:	Read Word
Format:	ULINEAR16,Absolute Only per VOUT_MODE
Phased:	No
Updates:	on-the-fly
NVM Back-up:	EEPROM or Pin Detection

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.

Table 8-41 Register Field Descriptions

Bit	Field	Access	Reset	Description
15:0	VOUT_ MIN	RW	NVM	Minimum output voltage. ULINEAR16 absolute per the setting of VOUT_ MODE.

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:

Set to the output voltage to current value of VOUT_MIN at the slew rate defined by VOUT_TRANSITION_RATE.
Set the NONE OF THE ABOVE in the STATUS_BYTE.
Set the VOUT bit in the STATUS_WORD.
Set the VOUT_MIN_MAX warning bit in STATUS_VOUT.
Notify the host per PMBus 1.3.1 Part II specification, section 10.2.

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.
