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
SUNNYVALE, Calif. --(BUSINESS WIRE)--
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.
