TCAN1042HVDRQ1

Drivers, Receivers, Transceivers Overview

The TCAN1042HVDRQ1 is a high-speed CAN transceiver from the TCAN1042HV series, designed for automotive applications. It supports data rates up to 2 Mb/s with half-duplex serial communication. The device operates on a supply voltage ranging from 4.5 V to 5.5 V and draws 45 mA of operating current. It features robust protection against bus faults up to 70 V and electrostatic discharge (ESD) ratings of 16 kV. Packaged in an SOIC-8 surface-mount format, it functions within a temperature range of -55°C to +125°C. Key electrical parameters include a propagation delay of 75 ns and power dissipation of 268 mW.

Drivers, Receivers, Transceivers Feature Summary

• Integrated 70-V bus fault protection for enhanced system reliability
• High ESD protection rating of 16 kV for robust signal integrity
• Automotive qualification compliant with AEC-Q100 standards

Drivers, Receivers, Transceivers Applications

• Automotive Controller Area Network (CAN) systems
• Industrial control networks requiring fault tolerance
• Embedded systems with strict environmental operating ranges

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix DRQ1 to confirm the SOIC-8 package and reel packaging configuration. Ensure compatibility with automotive grade requirements by checking the AEC-Q100 certification status. Confirm that the 70-V fault protection aligns with the target bus voltage specifications before integration into the design.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a 2 Mb/s data rate is sufficient and 70-V bus fault protection is required. Compare against the TCAN1042GDRQ1 if higher speeds up to 5 Mb/s are needed but lower fault tolerance is acceptable. Ensure the SOIC-8 footprint fits the PCB layout constraints and that the 4.5 V to 5.5 V supply range matches the system power architecture.

Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments TCAN1042HV family, which focuses on high-voltage fault protection capabilities. It serves as a specialized interface solution for harsh environments where standard transceivers might fail due to bus overvoltage events. The HV designation specifically indicates the enhanced fault protection features compared to standard variants.

Drivers, Receivers, Transceivers Replacement Considerations

The TCAN1042HGDQ1 offers similar fault protection but may differ in pinout or specific electrical characteristics; verify datasheet compatibility. For non-fault-protected alternatives, consider standard CAN transceivers if the 70-V protection is unnecessary.
