Insights

The AOZ1390DI ideal diode protection switch introduces significant advancements for USB Type-C power delivery applications. Its Power Source (LPS) feature acts as a important safeguard in multi-port systems, preventing excessive power flow from faulty ports. This addresses a key safety concern in high-power USB-C devices.

The device's 18 mΩ typical ON resistance is impressively low, minimizing power losses and heat generation. With a 3.3V to 23V operating range and 30V absolute maximum rating, it's versatile for various USB-PD applications up to 100W. The integrated back-to-back MOSFET design and advanced protection features like UVLO, OVP and TSD make it a robust solution for next-generation electronics.

At $1.40 per unit in 1000-piece quantities, it offers a cost-effective solution for manufacturers looking to enhance the safety and efficiency of their USB-C products. This product positions AOS competitively in the growing market for advanced USB-C power management solutions.

The launch of AOZ1390DI comes at a strategic time in the USB-C market. With the increasing adoption of USB-C in consumer electronics, there's a growing demand for efficient and safe power management solutions. This product addresses key pain points in multi-port designs, potentially giving AOS a competitive edge.

The market for USB-C power delivery ICs is expected to grow significantly, driven by the proliferation of high-power USB-C devices like laptops and monitors. AOS's innovation in safety features, particularly the LPS functionality, could be a key differentiator in this crowded market.

While the $1.40 price point is competitive, the real value proposition lies in the potential system-level cost savings and enhanced reliability it offers to OEMs. This could drive adoption among major electronics manufacturers, potentially boosting AOS's market share in the power management IC segment.

The advanced LPS feature of the AOZ1390DI significantly mitigates the risks in hazardous conditions

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 AOZ1390DI-01 and AOZ1390DI-02 ideal diode protection switches. The new devices are particularly well-suited for multi-port Type-C PD 3.0 current sinking applications up to 100W, such as high-performance laptops, personal computers, monitors, docking, and other Type-C port applications.

Designed to enhance USB Type-C efficiency and safety, the AOZ1390DI features Limited Power Source (LPS) functionality. For multi-port ORing or parallel power applications, the LPSB pin of the AOZ1390DI can be connected to the DISB pin of one or more AOZ1390DI devices at other ports. This LPS feature works as a watchdog, disabling the port when another port in the same system is faulty or damaged. In doing so it prevents excessive power flow through the device from other faulty or damaged ports, making the AOZ1390 ideal for multi-port Type-C Power Delivery (PD) applications.

The new device has advanced features that substantially reduce voltage drop and power loss compared to a discrete implementation. The AOZ1390DI offers an Ideal Diode True Reverse Current Blocking (IDTRCB) protection, which prevents the undesired reverse current from VOUT to VIN. 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. The input operating voltage range of the AOZ1390DI is between 3.3V and 23V, and both VIN and VOUT terminals are rated at 30V Absolute Maximum with the capability to support up to 8A switch current. 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) and Input Over-Voltage Protection (OVP). The FLTB pin flags Thermal Shut Down Protection (TSD), Short Circuit Protection (SCP), and Over Voltage faults.

“With our AOZ1390DI ideal diode protection switches, designers can implement simple, efficient, and safe USB Type-C PD3.0 Standard Power Range (SPR) current sinking applications up to 100W,” said Starry Tsai, Sr. Director of Product Marketing of Power IC Product Line at AOS. “With our unique Limited Power Source (LPS) feature, the reliable and safe design of systems with multiple Type C Ports is simplified. At the same time, AOS’ high SOA, low RDS(on) trench back-back MOSFETs enable an industry-leading low resistance, reducing the power dissipation in the system and enabling good thermal design.”

AOZ1390DI comes in two variants: AOZ1390DI-01 will automatically restart once fault conditions are cleared, whereas AOZ1390DI-02 will latch the power switch off, and the EN or power must be reset to restart the device.

  • 18 mΩ typical ON resistance
  • 3.3 V to 23 V operating input voltage, VIN, and VOUT rated at 30 V abs max.
  • Ideal Diode True Reverse Current Blocking (IDTRCB)
