Alpha and Omega Semiconductor Introduces a 20V, 7A Type-C Sourcing Protection Switch Designed to Enhance USB Type-C Efficiency and Safety - Seite 2

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.
