Alpha and Omega Semiconductor's sink and source switches enhance the performance capabilities of switches. Specifically, these switches are designed to increase the power delivery capability of USB Type-C® ports by up to 140 W, thereby paving the way for Type-C extended power range (EPR) implementations. The AOZ13937DI is tailored for 28 V Type-C sinking applications, while the AOZ15333DI is optimized for Type-C sourcing applications. These switches feature advanced characteristics to meet the stringent requirements of 28 V Type-C EPR implementations in high-performance laptops, personal computers, monitors, docking, and similar applications. The powerful AOZ13937DI sink switch is engineered to isolate and safeguard downstream components, offering ultra-low 20 mΩ typical ON resistance, soft-start, ideal diode true reverse-current blocking, overvoltage, reverse-current, short-circuit, overcurrent, overtemperature, and ESD protection. On the other hand, the AOZ15333DI companion source switch provides the necessary performance for sourcing 5 V at 3 A while blocking up to 28 V. Additionally, it is UL 2367 and IEC 62368-1:2018 (3rd edition) certified as a current limiting switch, adding an extra layer of safety to Type-C sourcing applications.
