Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The L99LDLH32TR is a monolithic 32-channel linear current regulator designed for automotive exterior O/LED rear side lighting applications. Due to the high-side configuration of the output channels, it is suitable for driving OLED panels with common cathode. It is guaranteed to provide up to 35 V output drive capability - covering a wide range of OLED forward voltages - and features 32 regulated current sources capable of delivering 1 mA-15 mA individually programmable currents to drive each pixel of the OLED panel independently. Another device in the same family (L99LDLL16) integrates a reliable, purely automotive CAN FD Light-compatible communication interface for high-rate data transfer (up to 1 mbit /s) and uses the CAN FD architecture for long frames. In addition to the CAN FD Light-compatible physical layer, the device also integrates a protocol handler, so that no additional external devices are required to communicate with the Commander ECU. the L99LDLH32TR can be operated in bus mode using the CAN FD Light-compatible interface or in standalone/fail-safe mode using the internal finitely programmable (FTP) memory register. fail-safe mode.

• 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.
