The TON_MAX_FAULT_RESPONSE 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 byte below 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, shutdown and restart according to TONMAX_RETRY. 10b: Shutdown Immediately and restart according to TONMAX_RETRY.Other: Invalid/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 1 - 6 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 1-7 ms, HICCUP equal to 2-7 times TON_RISE |
Attempts to write (63h) TON_MAX_FAULT_RESPONSE to any value outside those specified as valid, will be considered invalid/unsupported data and cause the TPS546D24S 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.
