| Bit | Field | Type | Default | Description |
|---|---|---|---|---|
| 7 | OTSD_MODE | R/W | 0b |
0b = Overtemperature condition will cause a latched fault 1b = Overtemperature condition will cause an automatic recovery when the fault condition is removed |
| 6-5 | OLP_SHTS_DLY | R/W | 10b |
00b = OLP delay is 0.25 ms and Shorts test delay is 0.1 ms 01b = OLP delay is 1.25 ms and Shorts test delay is 0.5 ms 10b = OLP delay is 5 ms and Shorts test delay is 2 ms 11b = OLP delay is 11.5 ms and Shorts test delay is 4.4 ms |
