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
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.”
