When a MTR_LCK
event happens in this mode, the status of MOSFETs
will be configured by MTR_LCK_MODE and nFAULT is
driven low. Status of MOSFETs during MTR_LCK:
- MTR_LCK_MODE = 0100b or 0101b: All
external MOSFETs are turned OFF, the gate driver
outputs pulled low.
- MTR_LCK_MODE = 0110b or 0111b: All
low-side MOSFETs (gate driver outputs) are turned
ON.
The CONTROLLER_FAULT, MTR_LCK and respective
motor lock condition 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, MTR_LCK and respective motor lock
condition bits are reset to 0b after the
t
LCK_RETRY period expires.
