The TON_MAX_FAULT_RESPONSE command instructs the device on what action to take in response to TON_MAX fault. Upon triggering the input TON_MAX fault, the converter responds per the following byte and the following actions are taken:
| 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
| RW | RW | RW | RW | RW | RW | RW | RW |
| TONMAX_RESP | TONMAX_RETRY | TONMAX_DELAY | |||||
| LEGEND: R/W = Read/Write; R = Read only |
| Bit | Field | Access | Reset | Description |
|---|---|---|---|---|
| 7:6 | TONMAX_ RESP | RW | NVM | TON_ MAX fault response 00b: Ignore. Continue operating without interruption. 01b: Continue operating for the delay time specified by TONMAX_DELAY. If the fault is still present, shut down and restart according to TONMAX_RETRY. 10b: Shut down immediately and restart according to TONMAX_RETRY. Other: Invalid or unsupported |
| 5:3 | TONMAX_ RETRY | RW | NVM | TON_MAX fault retry 0d: Do not attempt to restart (latch off). 1d - 6d: After shutting down, wait one HICCUP period, and attempt to restart up to one to six times. 7d: After shutting down, wait one HICCUP period, and attempt to restart indefinitely, until commanded OFF, or a successful start-up occurs. |
| 2:0 | TONMAX_ DELAY | RW | NVM | TON_MAX delay time for respond after delay and HICCUP 0d: Shutdown delay of 1 ms, HICCUP equal to TON_RISE 1d - 7d: Shutdown delay of 1 to 7 ms. HICCUP equal to two to seven times TON_RISE. |
Attempts to write (63h) TON_MAX_FAULT_RESPONSE to any value outside those specified as valid are considered invalid or unsupported data and cause the TPSM8D6C24 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.
