|Write Transaction:||Write Byte|
|Read Transaction:||Read Byte|
|Format:||Unsigned Binary (1 byte)|
The IOUT_OC_FAULT_RESPONSE instructs the device on what action to take in response to an overcurrent fault. Upon triggering the overcurrent fault, the TPSM8D6C24 responds according to the data byte below, and the following actions are taken:
|LEGEND: R/W = Read/Write; R = Read only|
|7:6||IO_OC_RESP||RW||NVM||Output ovecurrent response|
00b: Ignore. Continue operating without interruption.
01b: Ignore. Continue operating without interruption.
10b: Shutdown after Delay, as set by IO_OC_DELAY
11b: Shutdown Immediately
|5:3||IO_OC_RETRY||RW||NVM||Output overcurrent 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||IO_OC_DELAY||RW||NVM||Output overcurrent 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 Section 7.6.40 to any value outside those specified as valid will be considered invalid/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.
