Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The TLE7257SJ is a transceiver for the Local Interconnect Network (LIN) with integrated wake-up and protection features. It is designed for invehicle networks using data transmission rates up to 20 kbps. The TLE7257SJ  operate as a bus driver between the protocol controller and the physical bus of the LIN network. Compliant to all LIN standards and with a wide operational supply range the TLE7257SJ can be used in all automotive applications. 

The usage of different operation modes and the INH output allows the TLE7257SJ to control external components like e.g. voltage regulators. In Sleep mode the TLE7257SJ draws typically less than 10 μA of quiescent current while still being able to wake-up when detecting LIN bus traffic. The very low leakage current on the BUS pin makes the TLE7257SJ especially suitable for partially supplied networks. 

Based on the Infineon BiCMOS technology the TLE7257SJ provides excellent ESD robustness together with a very high electromagnetic compatibility (EMC). The TLE7257SJ reaches a very low level of electromagnetic emission (EME) within a broad frequency range and independent from the battery voltage. The TLE7257SJ is AEC qualified and tailored to withstand the harsh conditions of the automotive environment.

• 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.
