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: All MOSFETs are turned OFF.
- MTR_LCK_MODE = 0101b: MOSFET
which was switching is turned OFF while the one which was conducting
stays ON till inductive energy is completely recirculated.
- MTR_LCK_MODE = 0110b: All high-side MOSFETs are turned ON.
- MTR_LCK_MODE = 0111b: All low-side MOSFETs 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.
