R/W-0b | R/W-01b | R/W-01b | R/W-1b | R/W-11b |
Bit | Field | Type | Default | Description |
---|---|---|---|---|
7 | COAST | R/W | 0b |
Write a 1 to this bit to put all the MOSFETs in the Hi-Z state |
6-5 | TRETRY | R/W | 01b |
00b = 2 ms 01b = 4 ms 10b = 6 ms 11b = 8 ms |
4-3 | DEAD_TIME | R/W | 01b |
00b = 500 ns 01b = 1000 ns 10b = 2000 ns 11b = 4000 ns |
2 | TDRIVE_MAX | R/W | 1b |
Write a 0 to this bit to disable the maximum tDRIVE time of 20 µs. This bit is automatically enabled when IDRIVE = 0000b, 0001b, 0010b, or 0011b is selected |
1-0 | TDRIVE | R/W | 11b |
00b = 500 ns peak gate-current drive time 01b = 1000 ns peak gate-current drive time 10b = 2000 ns peak gate-current drive time 11b = 3000 ns peak gate-current drive time |
