Alpha and Omega Semiconductor, in Booth #810 at APEC, will showcase a pair of sink and source switches that can increase the power-delivery capability of USB Type-C ports to 140 W, paving the way for Type-C extended power range (EPR) implementations.
The AOZ13937DI is equipped to handle 28-V Type-C sinking applications, while the AOZ15333DI is capable of Type-C sourcing apps. These new switches are suited for 28-V Type C EPR implementations in high-performance laptops, personal computers, monitors, docking stations, and other applications.
The AOZ13937DI features an ultra-low, 20-mΩ resistance with soft-start, overvoltage, ideal-diode reverse-current, short-circuit, overcurrent, overtemperature, and ESD protections. It's 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 5 V at 3 A while blocking up to 28 V. 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), overtemperature (OTP) protection, and it has a programmable ILIMIT pin.
The AOZ15333DI and AOZ13937DI are available in production quantities with a lead time of 16 weeks. The unit price in 1,000-piece quantities is $0.84 USD for the AOZ15333DI and $1.10 USD for the AOZ13937DI. AOS products are offered in packages with Pb-free plating and are RoHS-compliant.
