Alpha and Omega Semiconductor introduced sink and source switches that can increase the power delivery capability of USB Type-C ports to 140W, paving the way for Type C extended power range (EPR) implementations. The AOZ13937DI is suited for 28V Type C sinking applications while the AOZ15333DI is capable of Type C sourcing applications. These new switches are suited for 28V Type C EPR implementations in high-performance laptops, personal computers, monitors, docking, and other applications.

The AOZ13937DI features an ultra-low 20mOhm resistance with soft-start, overvoltage, ideal diode reverse-current, short-circuit, over-current, over-temperature, and ESD and is designed to isolate and protect downstream components from abnormal VBUS voltage and current conditions.

The ideal diode fast reverse current protection allows multiple power paths to be connected in parallel without interference.

The AOZ15333DI companion source switch IC is capable of sourcing 5V @ 3A while blocking up to 28V. AOZ15333DI is UL 2367 and IEC 62368-1:2018 (3rd Edition) certified as a current limiting switch suited for Type C sourcing applications. The device is protected against numerous fault conditions such as VIN Overvoltage Protection (OVP), Startup Short circuit protection (SCP), and Over-temperature (OTP) protection and has a programmable ILIMIT pin.
