The advanced features of the AOZ1377DI capable
to support up to 7A at max 23VIN and programmable current limit,
and true reverse current blocking protection
Alpha and Omega Semiconductor Limited (AOS) (Nasdaq: AOSL), a
designer, developer, and global supplier of a broad range of
discrete power devices, wide band gap power devices, power
management ICs, and modules, today announced the release of its
AOZ1377DI Type-C Protection Switch. Designed to enhance USB Type-C
efficiency and safety, these new protection Type-C switches have a
current-limiting switch targeting applications that require
comprehensive protections. AOZ1377DI boasts a unique feature
supporting up to 7A with an input voltage of up to 20V input
voltage, making it versatile for both Sink and Source
applications.

The AOZ1377DI offers advanced features that significantly reduce
voltage drop and power loss compared to back-to-back p-channel
devices typically used in such applications. The device supports an
input operating voltage range of 3.4V to 23V, with both VIN and
VOUT terminals rated at a maximum of 28V, and is capable of up to
7A. These devices are ideal for high-power applications requiring
multi-port Type-C PD 3.0 current source supporting up to 100W. They
are particularly well-suited for use in high-performance laptops,
personal computers, monitors, docking stations, and other Type-C
port applications.
The AOZ1377DI has a True Reverse Current Blocking (TRCB)
protection, which prevents undesired reverse current from VOUT to
VIN. It also features an internal current-limiting and
short-circuit current limit that protects the source device from
large load current. The current limit threshold can be set
externally with a resistor. Furthermore, the integrated
back-to-back MOSFET delivers the industry’s lowest ON resistance
and highest SOA to safely handle high currents and a wide range of
output capacitances on VOUT. An internal soft-start circuit
controls inrush current from high capacitive loads, and an external
capacitor can adjust the slew rate.
In addition, it has a wealth of protection features, including
input Under-Voltage Lock Out (UVLO), Input Over-Voltage Protection
(OV), and Thermal Shut Down Protection (TSD). In shutdown, the
device consumes a mere 3uA.
“The AOZ1377DI offers a highly integrated solution for Type C
sourcing up to 20V and is capable of sourcing over 140W for systems
implementing a high-power source. To simplify system compliance
testing, the AOZ1377DI is UL 2367 and IEC62368-1 certified,” said
Jongchul Song, Sr. Marketing Manager for Protected Switch products
at AOS.
AOZ1377DI comes in two variants: AOZ1377DI-01 will automatically
restart once fault conditions are cleared, whereas AOZ1377DI-02
will latch the power switch off, and the EN must be reset to
restart the device.
