Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The TJA1044T is a member of the Mantis series of high-speed CAN transceivers. It provides an interface between the CAN protocol controller and the physical two-wire CAN bus. This transceiver is specifically designed for high-speed CAN applications in the automotive industry, enabling the CAN protocol controller (in the microcontroller) to transmit and receive differential signals. The CAN bus exhibits ideal passive performance when the power is disconnected.

The TJA1044T features an ultra-low current standby mode with bus wake-up functionality, offering excellent electromagnetic compatibility even without a common-mode inductor. Models with a VIO pin can be directly connected to microcontrollers with a power supply voltage of 3.3V to 5V

These features make the TJA1044T an ideal choice for all types of high-speed CAN networks, particularly for nodes requiring low-power modes and wake-up functionality via the CAN bus.

The TJA1044T implements the CAN physical layer as defined in the current 11898-2:2016 and SAE J2284-1 to SAE J2284-5 standards. The TJA1044T supports data transfer rates up to 1 Mbit/s. Other models also define other timing parameters for loop delay symmetry. In CAN FD fast mode, it enables reliable communication even at data rates up to 5 Mbit/s.

General Features

Fully compliant with ISO 11898-2:2016, SAE J2284-1 to SAE J2284-5, and SAE J1939-14 standards

Ultra-low current standby mode with local and bus wake-up functionality

Optimised for use in 12V automotive systems

Capable of low electromagnetic emission (EME) and high electromagnetic compatibility (EMI), meeting proposed EMC standards such as IEC 62228-3 and SAE J2962-2.

AEC-Q100 certified

Deep green product (halogen-free and compliant with Restriction of Hazardous Substances (RoHS) regulations)

Models with VIO pins can be directly connected to microcontrollers operating at 3.3V to 5V.

Models without VIO pins can be connected to microcontrollers powered by 3.3V (except TJA1044C) and 5V, provided the microcontroller's I/O voltage tolerance is 5V.

• 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.
