Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The DRV3245SQPHPRQ1 device is a FET gate driver IC for three-phase motor drive applications and is designed to meet the requirements of ISO 26262 for functional safety applications. The device features three half-bridge drivers, each capable of driving both high-side and low-side N-channel MOSFETs, along with advanced FET protection and monitoring. The charge pump drivers achieve 100% duty cycle during cold start operation and support low battery voltages. With integrated current-sense amplifiers, phase comparators, and SPI-based configuration and peripherals, the drivers eliminate most external and passive components, reducing bill of materials and printed circuit board (PCB) space.

The DRV3245SQPHPRQ1 device also integrates diagnostic and protection functions for the internal clock and provides support for common system diagnostic checks, both of which can be instantiated and reported via SPI. The flexibility of this integrated functionality allows the device to be seamlessly integrated into a variety of security architectures.

• 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.
