Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Designed for single-axis magnetic field detection applications, the DRV425QWRTJRQ1 automotive class device enables accurate measurements of DC and AC magnetic fields with galvanic isolation and high sensitivity. The device provides an internal compensation coil to a unique and proprietary integrated fluxgate sensor (IFG) to support a high accuracy detection range of ±2mT and a measurement bandwidth of up to 47kHz. The sensor's low offset voltage, low drift, and low noise, combined with the precise gain, low gain drift, and extremely low nonlinearity provided by the built-in compensation coil, provide unrivalled magnetic field measurement accuracy. High sensitivity and accuracy enable a wider range of current measurements in high current busbar applications such as traction inverters or battery management systems. Torque sensors or motor diagnostic systems benefit from the ability to accurately measure magnetic field position or displacement. The output of the DRV425-Q1 is an analogue signal proportional to the detected magnetic field.

The device offers complete functionality, including an internal differential amplifier, an on-chip precision reference, and diagnostic capabilities to minimise component count and cut system-level costs.

The device is available in a thermally enhanced, non-magnetic, thin WQFN package with heat sinks optimised for thermal dissipation, and is rated for automotive operation over the -40°C to +125°C temperature range.

• 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.
