Alpha and Omega Semiconductor Introduces a Powerful New Duo of Protection Switches for Type C EPR 3.1

The AOZ13937DI Type C sink and AOZ15333DI Type C source protection switches enable efficient and safe Type C EPR 3.1 Designs up to 140W

SUNNYVALE, Calif. — (BUSINESS WIRE) — March 14, 2023 — Alpha and Omega Semiconductor Limited (AOS) (Nasdaq: AOSL), a designer, developer, and global supplier of a broad range of power semiconductors, power ICs, and digital power products, today introduced a powerful duo of 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. Both the AOZ13937DI and AOZ15333DI sink and source switches are being introduced in conjunction with AOS’ participation in the upcoming APEC 2023 Conference being held March 19 – 23 in Orlando, Florida.

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), Over-temperature (OTP) protection and has a programmable ILIMIT pin.

“The AOZ13937DI and AOZ15333DI are a powerful duo of protection switches to allow simple, efficient, and safe implementations of USB Type-C PD3.1 Extended Power Range (EPR) up to 140W,” said Ralph Monteiro, VP, Power ICs at AOS. “With the ability to withstand up to +39V on VBUS, the new sink and source switches deliver the safety margin required by our customers to build 28V systems. At the same time, AOS’ high SOA, low RDS(on) trench MOSFETs enable an industry-leading low-resistance 20mΩ back-back MOSFET, reducing the power dissipation in the system and enabling good thermal design.”
