|Format:||Unsigned Binary (1 byte)|
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:
|LEGEND: R/W = Read/Write; R = Read only|
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.
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.
TON_MAX delay time for respond after delay and HICCUP
0d: Shutdown delay of 0 ms, HICCUP equal to TON_RISE
1d - 7d: Shutdown delay of 1 - 7 ms, HICCUP equal to 1 - 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 TPS546B24A 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.
