Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The UCC5390ECDWVR is a single-channel isolated gate driver from Texas Instruments, packaged in an 8-SOIC package, specifically designed for driving power switching devices (such as IGBTs, SiC MOSFETs, and GaN FETs) in high-voltage, high-noise environments. Its key features include a 3kVrms isolation voltage, 10A peak output current, and 100kV/µs common-mode transient immunity (CMTI), making it suitable for applications such as industrial power supplies, motor drives, photovoltaic inverters, and electric vehicle charging systems.

UCC5390ECDWVR Core Features

High isolation voltage: 3000Vrms (1 minute), compliant with UL 1577 and VDE V 0884-11 safety certifications.

Capacitive coupling isolation technology, with an isolation layer lifespan exceeding 40 years.

High-speed drive capability: 10A peak output current, enabling rapid switching of SiC/GaN power devices.  

Propagation delay ≤100ns, rise/fall time 10ns, optimising high-frequency switching efficiency.  

Strong anti-interference performance: CMTI ≥100kV/µs, preventing noise-induced false triggering.  

Input side supports -5V negative voltage, enhancing system robustness.

Wide power supply range: input voltage 3V to 15V, drive-side voltage 13.2V to 33V, compatible with various power architectures.  

Industrial-grade reliability: operating temperature -40°C to +125°C, suitable for harsh environments.  

Compliant with CQC, CSA, VDE, and other certifications.

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?

  A: the delivery date is marked in most commodity information. You can estimate the delivery time of the commodity according to the delivery date. The specific arrival time depends on the warehouse where the commodity is located and the logistics mode you choose.

• 6.Can the company issue an invoice?
