Ideal diode controllers are extensively used in automotive applications to improve power efficiency and protect systems from reverse voltage and reverse current conditions. These controllers work with external N-channel MOSFETs—either in single or back-to-back configurations—to create low-loss rectifiers. This architecture significantly reduces power dissipation compared to traditional diodes or P-channel MOSFETs, while also providing robust protection against reverse polarity and reverse current faults where required. As a result, ideal diodes controllers offer a highly efficient and reliable solution for modern automotive power architectures.
