Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The UCC44273DBVR single-channel, high-speed, low-side gate driver device is capable of efficiently driving MOSFET and IGBT power switches.The UCC44273 is designed with inherent minimum breakdown current to deliver high peak current pulses to capacitive loads with rail-to-rail drive capability and very low propagation delays (typically 13 ns).

The input pins of the UCC44273DBVR device are capable of withstanding -5 V. The UCC44273 has 4 A source and 4 A sink (symmetrical drive) peak drive current capability at VDD = 12 V. The UCC44273DBVR is designed to provide high peak current pulses to capacitive loads with rail-to-rail drive capability and very low propagation delay (typically 13 ns).

The UCC44273DBVR operates over a wide VDD range of 4.5 V to 18 V and over a wide temperature range of -40°C to 140°C. An internal undervoltage lockout (UVLO) circuit on the VDD pin holds the output low outside the VDD operating range.

Motor Drivers

• 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?

  A: you can issue ordinary invoices for individual users or special VAT invoices for enterprise users.
