| RSVD | OTW_REP | CBC | DIS_VDS_C | DIS_VDS_B | DIS_VDS_A | OCP_MODE | |
| R/W-0b | R/W-0b | R/W-0b | R/W-0b | R/W-0b | R/W-0b | R/W-00b | |
| Bit | Field | Type | Default | Description |
|---|---|---|---|---|
| 7 | RSVD | R/W | 0b |
Reserved |
| 6 | OTW_REP | R/W | 0b |
0b = Overtemperature warning is not reported on nFAULT 1b = Overtemperature warning is reported on nFAULT |
| 5 | CBC | R/W | 0b |
In retry OCP_MODE, for both VDS_OCP, the fault is automatically cleared when a PWM input is given |
| 4 | DIS_VDS_C | R/W | 0b |
Write a 1 to this bit to disable VDS_OCP for MOSFETs in Phase C |
| 3 | DIS_VDS_B | R/W | 0b |
Write a 1 to this bit to disable VDS_OCP for MOSFETs in Phase B |
| 2 | DIS_VDS_A | R/W | 0b |
Write a 1 to this bit to disable VDS_OCP for MOSFETs in Phase A |
| 1-0 | OCP_MODE | R/W | 00b |
00b = Overcurrent causes a latched fault 01b = Overcurrent causes an automatic retrying fault 10b = Overcurrent is report only but no action is taken 11b = Overcurrent is not reported and no action is taken |
