(56h) VIN_OV_FAULT_RESPONSE

CMD Address56h
Write Transaction:Write Byte
Read Transaction:Read Byte
Format:Unsigned Binary (1 byte)
Phased:No
NVM Back-up:EEPROM
Updates:On-the-fly

The VIN_OV_FAULT_RESPONSE command instructs the device on what action to take in response to a PVIN Overvoltage Fault. Upon triggering the PVIN overvoltage fault, the converter responds per the data byte below, and the following actions are taken:

  • Set the NONE OF THE ABOVE bit in the STATUS_BYTE register.
  • Set the INPUT bit in the upper byte of the STATUS_WORD register.
  • Set the VIN_OV bit in the STATUS_INPUT register.
  • Notify the host per PMBus 1.3.1 Part II specification, section 10.2.

00b: Ignore. Continue operating without interruption.
01b: Delayed Shutdown Continue Operating for a number of switching cycles defined by VIN_OVF_DLY, then if fault persists, shut down and restart according to VIN_OV_RETRY.
10b: Immediate Shutdown. Shut down and restart according to VIN_OV_RETRY.
11b: Invalid / Not Supported
5:3VIN_OVF_ RETRYRWNVMPVIN Overvoltage retry
0d: Do not attempt to restart (latch off).
1d-6d: After shutting down, wait one HICCUP period, and attempt to restart up to 1 - 6 times. After 1 - 6 failed restart attempts, do not attempt to restart (latch off). Restart attempts that occur while PVIN voltage is above VIN_OV_FAULT_LIMIT will not be observable but will be counted
7d: After shutting down, wait one HICCUP period, and attempt to restart indefinitely, until commanded OFF, or a successful start-up occurs.
2:0VIN_OVF_ DLYRWNVMPVIN Overvoltage 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 (56h) VIN_OV_FAULT_RESPONSE to any value outside those specified as valid will be considered invalid/unsupported data and cause the TPSM8S6B24 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.
