Fault_EnableShortCircuitProtection()

static void Fault_EnableShortCircuitProtection ( void  )

static

Returns

void

This function setup the short circuit protection threshold and turns on the DAC (Digital-to-Analog) module. This hardware protection use Comparator DACs to detect short circuit.

void

)

Returns

void

This function evaluates if any of the fault objects has been tripped. When fault detection occurs, the power converter will shutdown thus turn-off the power converter.

Returns

void

This function checks if the board temperature is within the nominal operating range. When value exceeds the limit, the power control can trip or perform temperature derating for temperature fault.

Fault_Handler()

void Fault_Handler

(

void

)

Returns

void

This function handles the occurence of fault when one of the fault condition trips. It shuts down the operation of the power control, set the FaultActive bit and clear the Running bit indicating that power converter has been turned-off. A fault pin is also set to low to blocked the PWM signal as a hardware protection.

)

Returns

void

This function initializes the fault objects following each respective fault thresholds.

void Fault_Reset

(

void

)

Returns

void

This function clears the fault status bits for Fault Active and Fault Latched. A fault pin is also drive to high to allow PWM signal drive.
