SLLSFH8B August 2021 – February 2022 MCT8316A
When a CBC_ILIMIT event happens in this mode, MCT8316A stops driving the FETs using recirculation mode to prevent the inductive energy from entering the DC input supply. The CBC_ILIMIT bit is set to 1b in the fault status registers. Normal operation resumes after (CBC_RETRY_PWM_CYC +1) PWM cycles and CBC_ILIMIT bit is set to 0b. The status of CONTROLLER_FAULT bit and nFAULT pin will be determined by CBC_ILIMIT_MODE. When CBC_ILIMIT_MODE is 0100b, CONTROLLER_FAULT bit is set to1b and nFAULT pin driven low until (CBC_RETRY_PWM_CYC +1) PWM cycles lapse. When CBC_ILIMIT_MODE is 0101b, CONTROLLER_FAULT bit is not set to 1b and nFAULT is not driven low.
