Fault Condition Tolerance

Fault conditions are designed into every system to ensure the system can handle extreme conditions during the module’s lifetime. Looking here at the fault condition tolerance, both products are likely suitable for general operations; it is when things go wrong that Nexperia’s half-bridge package excels. For example, in the motor control space the MOSFET needs to be able to handle motor stall. What happens in motor stall conditions is that the energy needs to be dissipated through the MOSFET. The lower thermal performance of Nexperia’s half-bridge MOSFET offers a bigger head room to handle this energy compared to the competition. Short-circuit is a similar message; again, a similar head room is needed.
