HVDA1040AQDSJRQ1

Overview

The HVDA1040AQDSJRQ1 is a high-speed CAN transceiver from Texas Instruments, designed for automotive EMC-optimized applications. It operates within a supply voltage range of 4.75 V to 5.25 V and supports data rates up to 1 Mb/s. The device features one driver and one receiver, housed in an 8-pin DSBGA package suitable for surface-mount technology. It functions reliably across a temperature range of -40°C to +125°C, with a typical operating supply current of 50 mA. ESD protection is rated at 12 kV, and it holds AEC-Q100 qualification.

Feature Summary

• High-speed CAN communication capability optimized for automotive electromagnetic compatibility
• Robust electrostatic discharge protection rating for harsh environments
• Automotive-grade reliability certified under AEC-Q100 standards

Applications

• Automotive CAN bus networks requiring EMC optimization
• Embedded control modules in electric vehicles
• Industrial automation systems utilizing CAN interface protocols

Procurement Notes

Verify the specific suffix DSJR against official Texas Instruments documentation to confirm package type and tape-and-reel specifications. Ensure the component meets the required AEC-Q100 grade for your target application. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status prior to integration into final assemblies.

Selection Notes

Select this component when designing automotive CAN interfaces that demand high EMC performance and robust ESD protection. Compare its 1 Mb/s data rate and 50 mA supply current against system power budgets. Evaluate the compact DSBGA package dimensions against available PCB real estate constraints. Consider thermal dissipation requirements given the operating temperature range and power consumption characteristics.

Part Context

This part belongs to the SN65HVDA1040 family of high-speed CAN transceivers. It shares functional similarities with other members like the SN65HVD1040 but differs in packaging and specific automotive qualification details. The family is designed to provide reliable communication in noisy automotive environments while maintaining low power consumption.

Replacement Considerations

Direct substitutes include SN65HVDA1040BQDRQ1 or SN65HVD1040AQDRQ1, provided the package difference (DSBJR vs DR) is accommodated by the design. Verify pinout compatibility and electrical parameters before substitution.
