Bit | Field | Type | Default | Description |
---|---|---|---|---|
10 | Reserved | R/W | 0b |
Reserved |
9 | DIS_CPUV | R/W | 0b |
0b = Charge pump UVLO fault is enabled 1b = Charge pump UVLO fault is disabled |
8 | DIS_GDF | R/W | 0b |
0b = Gate drive fault is enabled 1b = Gate drive fault is disabled |
7 | OTW_REP | R/W | 0b |
0b = OTW is not reported on nFAULT or the FAULT bit 1b = OTW is reported on nFAULT and the FAULT bit |
6-5 | PWM_MODE | R/W | 00b |
00b = 6x PWM Mode 01b = 3x PWM mode 10b = 1x PWM mode 11b = Independent PWM mode |
4 | 1PWM_COM | R/W | 0b |
0b = 1x PWM mode uses synchronous rectification 1b = 1x PWM mode uses asynchronous rectification (diode freewheeling) |
3 | 1PWM_DIR | R/W | 0b |
In 1x PWM mode this bit is ORed with the INHC (DIR) input |
2 | COAST | R/W | 0b |
Write a 1 to this bit to put all MOSFETs in the Hi-Z state |
1 | BRAKE | R/W | 0b |
Write a 1 to this bit to turn on all three low-side MOSFETs in 1x PWM mode.
|
0 | CLR_FLT | R/W | 0b |
Write a 1 to this bit to clear latched fault bits.
