SLLSFH8A August 2021 – December 2021 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 at the start of next PWM cycle and CBC_ILIMIT bit is reset to 0b. The status of CONTROLLER_FAULT bit and nFAULT pin will be determined by CBC_ILIMIT_MODE. When CBC_ILIMIT_MODE is 0000b, CONTROLLER_FAULT bit is set to 1b and nFAULT pin driven low until next PWM cycle. When CBC_ILIMIT_MODE is 0001b, CONTROLLER_FAULT bit is not set to 1b and nFAULT is not driven low.
