8.6.38 (45h) VOUT_UV_FAULT_RESPONSE

CMD Address	45h
Write Transaction:	Write Byte
Read Transaction:	Read Byte
Format:	Unsigned Binary (1 byte)
Phased:	No
NVM Back-up:	EEPROM
Updates:	On-the-fly

The VOUT_UV_FAULT_RESPONSE instructs the device on what action to take in response to an output undervoltage fault.

The VOUT_UV_FAULT_RESPONSE instructs the device on what action to take in response to an output undervoltage fault. Upon triggering the overvoltage fault, the TPSM8S6C24 responds according to the data byte below, and the following actions are taken:

Set the NONE OF THE ABOVE bit in the STATUS_BYTE.
Set the VOUT bit in the STATUS_WORD.
Set the VOUT_UVF bit in the STATUS_VOUT register.
Notify the host per PMBus 1.3.1 Part II specification, section 10.2.

Table 8-55 Register Field Descriptions

Bit	Field	Access	Reset	Description
7:6	VO_ UV_ RESP	RW	NVM	Output undervoltage response 00b: Ignore. Continue operating without interruption. 01b: Shutdown after Delay, as set by VO_UV_DELY 10b: Shutdown Immediately Other: Invalid/Unsupported
5:3	VO_ UV_ RETRY	RW	NVM	Output undervoltage retry 0d: Do not attempt to restart (latch off). 1d-6d: After shutting down, wait one HICCUP period, and attempt to restart upto 1 - 6 times. After 1 - 6 failed restart attempts, do not attempt to restart (latch off). 7d: After shutting down, wait one HICCUP period, and attempt to restart indefinitely, until commanded OFF, or a successful start-up occurs.
2:0	VO_ UV_ DLY	RW	NVM	Output undervoltage delay time for respond after delay and HICCUP 0d: Shutdown delay of one PWM_CLK, HICCUP equal to TON_RISE 1d: Shutdown delay of one PWM_CLK, HICCUP equal to TON_RISE 2d - 4d: Shutdown delay of three PWM_CLK, HICCUP equal to 2 - 4 times TON_RISE 5d - 7d: Shutdown delay of seven PWM_CLK, HICCUP equal to 5 - 7 times TON_RISE

Attempts to write (45h) VOUT_UV_FAULT_RESPONSE 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.
