When a LOCK_ILIMIT event happens in this mode, the status of external MOSFETs will be configured by LOCK_ILIMIT_MODE and nFAULT is driven low. Status of external MOSFETs driven from MCF8329A during LOCK_ILIMIT:
- LOCK_ILIMIT_MODE = 0100b or 0101b: All MOSFETs
are turned OFF, the gate driver outputs pulled low.
- LOCK_ILIMIT_MODE = 0110b or 0111b: All low-side
MOSFETs (gate driver outputs) are turned ON
The CONTROLLER_FAULT and LOCK_ILIMIT bits are set to 1b in the fault status registers. Normal operation resumes automatically (gate driver operation and the nFAULT pin is released) after the t
LCK_RETRY (configured by LCK_RETRY) time lapses. The CONTROLLER_FAULT and LOCK_ILIMIT bits are reset to 0b after the t
LCK_RETRY period expires.
