Bit | Field | Type | Default | Description |
---|---|---|---|---|
7-5 | LOCK | R/W | 011b |
Write 110b to lock the settings by ignoring further register writes except to these bits and address 0x04h bit 7 (CLR_FLT). Writing any sequence other than 110b has no effect when unlocked. Write 011b to this register to unlock all registers. Writing any sequence other than 011b has no effect when locked. |
4 | DIS_CPUV | R/W | 0b |
0b = Charge-pump undervoltage lockout fault is enabled 1b = Charge-pump undervoltage lockout fault is disabled |
3 | DIS_GDF | R/W | 0b |
0b = Gate drive fault is enabled 1b = Gate drive fault is disabled |
2-0 | OCP_DEG | R/W | 001b |
000b = 2.5 µs 001b = 4.75 µs 010b = 6.75 µs 011b = 8.75 µs 100b = 10.25 µs 101b = 11.5 µs 110b = 16.5 µs 111b = 20.5 µs |
