Shenzhen Mingjiada Electronics Co., Ltd., as a leading distributor of electronic components in China, specialises in supplying TI's HVDA541QDRQ1 automotive-grade 5V CAN transceiver chip. This high-performance transceiver is specifically designed for automotive and industrial applications, featuring input/output level matching functionality and power-optimised low-power mode characteristics, capable of meeting the stringent requirements for reliable communication in modern in-vehicle networks and industrial automation systems.
Product Overview and Technical Features Of HVDA541QDRQ1
The HVDA541QDRQ1 is an automotive-grade CAN transceiver compliant with the AEC-Q100 standard, packaged in an 8-pin SOIC package, specifically designed for Controller Area Network (CAN) applications in automotive and industrial systems. The HVDA541QDRQ1 transceiver incorporates multiple functional optimisations over traditional CAN transceivers, making it an ideal choice for in-vehicle network communication.
In terms of key electrical parameters, the HVDA541QDRQ1 operates within a voltage range of 4.68V to 5.33V and supports a data transfer rate of 1Mbps, meeting the requirements of most in-vehicle CAN network communication applications. Its operating temperature range spans -40°C to +125°C, ensuring stable performance even in extreme environments and meeting the stringent temperature adaptability requirements of automotive electronics.
The most notable technical highlight of the HVDA541QDRQ1 device is its I/O level adaptation functionality, which allows direct connection to 3.3V or 5V microcontrollers without the need for additional level conversion circuits, simplifying system design and reducing BOM costs. Additionally, the HVDA541QDRQ1's optimised low-power mode power supply design significantly reduces static current, minimising power consumption in standby mode, making it ideal for power-sensitive automotive applications.
In terms of protection features, the HVDA541QDRQ1 integrates multiple protection mechanisms:
Bus fault protection capability up to ±58V
Thermal shutdown protection (TSD) to prevent overheating damage
Driver-dominated timeout (TXD DTO) function to ensure communication reliability
High interference immunity, with a receiver common-mode input voltage range of ±30V
These protection features collectively form a robust communication interface capable of withstanding common issues in automotive electronic environments, such as power fluctuations, short circuits, and electromagnetic interference.
