Smart Protection Switches with Ideal Diode True Reverse Current Blocking for Type-C PD Applications
Alpha and Omega Semiconductor has announced a new Type-C Power Delivery high voltage sink protection switch using ideal diode methodology for reverse current protection. New AOZ13984DI-02 and AOZ13987DI-02 are smart protection switches in a single small thermally enhanced 3mm x 3mm DFN package. These new devices offer low RDS(ON) (20mohm) back-to-back MOSFETs to block any reverse current under fault conditions and are capable of up to 28V absolute maximum voltage. Moreover, these products use AOS’s advanced co-packaging technology, combining a high-performance IC with protection features and our latest high SOA Trench MOSFET.
These smart protection switches feature Ideal Diode True Reverse Current Blocking (IDTRCB), allowing no reverse current at any conditions. They also feature 28V absolute maximum voltage with startup SOA management and other protections.
