LOCK_ILIMIT_MODE

R/W

Lock detection current limit mode

0h = Ilimit lock detection causes latched fault; nFAULT active; Gate

driver is tristated

1h = Ilimit lock detection causes latched fault; nFAULT active; Gate

driver is in recirculation mode

2h = Ilimit lock detection causes latched fault; nFAULT active; Gate

driver is in high-side brake mode (All high-side FETs are turned ON)

3h = Ilimit lock detection causes latched fault; nFAULT active; Gate

driver is in low-side brake mode (All low-side FETs are turned ON)

4h = Automatic recovery after tLCK_RETRY; Gate driver is tristated

5h = Automatic recovery after tLCK_RETRY; Gate driver is in

recirculation mode

6h = Automatic recovery after tLCK_RETRY; Gate driver is in high-

side brake mode (All high-side FETs are turned ON)

7h = Automatic recovery after tLCK_RETRY; Gate driver is in low-

side brake mode (All low-side FETs are turned ON)

8h = Ilimit lock detection is in report only but no action is taken

9h = Ilimit lock detection is disabled

Ah = Ilimit lock detection is disabled

Bh = Ilimit lock detection is disabled

Ch = Ilimit lock detection is disabled

Dh = Ilimit lock detection is disabled

Eh = Ilimit lock detection is disabled

Fh = Ilimit lock detection is disabled
