TPT1051Q-DF6R-S

Drivers, Receivers, Transceivers Overview

The TPT1051Q-DF6R-S is an automotive-grade, half-duplex CAN FD transceiver manufactured by 3PEAK. It complies with ISO 11898-2:2016 and SAE J2284 standards, supporting data rates up to 5 Mbps. The device operates on a 4.5 V to 5.5 V supply (VCC) and features a secondary VIO pin for I/O level shifting between 2.8 V and 5.5 V. It utilizes a leadless DFN3x3-8 package and functions within an ambient temperature range of -40°C to +125°C. Key electrical characteristics include ±70 V bus fault protection, ±30 V common-mode input voltage, and IEC 61000-4-2 ESD protection rated at ±15 kV.

Drivers, Receivers, Transceivers Feature Summary

• Supports high-speed CAN FD networks up to 5 Mbps with enhanced timing margins for long or highly loaded buses.
• Includes a dedicated Silent Mode (listen-only) controlled via the S pin to prevent faulty nodes from disrupting network communication.
• Provides robust protection against crosswiring, overvoltage, ground loss, and thermal shutdown, ensuring ±70 V bus fault tolerance.
• Features ideal passive behavior when unpowered, maintaining low leakage current to preserve network integrity.

Drivers, Receivers, Transceivers Applications

• Automotive body electronics and lighting systems
• Powertrain and chassis control modules
• Infotainment systems and instrument clusters
• Advanced Driver Assistance Systems (ADAS) and safety-critical applications

Drivers, Receivers, Transceivers Procurement Notes

Verify that the specific suffix DF6R corresponds to the DFN3x3-8 package variant required for the design. Confirm AEC-Q100 Grade 1 qualification status matches the target automotive reliability requirements. Ensure the silent mode control logic aligns with the active-high specification for the S pin during system integration.

Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring strict compliance with ISO 11898-2:2016 physical layer standards. The inclusion of a separate VIO supply allows direct interfacing with MCUs operating at 2.8 V, 3.3 V, or 5 V logic levels without external level shifters. Consider the DFN3x3-8 package for space-constrained PCB layouts compared to larger SOP packages.

Drivers, Receivers, Transceivers Part Context

This part belongs to the TPT1051 family of automotive CAN transceivers. The 'Q' suffix indicates AEC-Q100 Grade 1 qualification for automotive use. The 'DF6R' suffix specifies the DFN3x3-8 leadless package type. The 'S' typically denotes standard tape-and-reel packaging. This series is designed to replace legacy CAN transceivers in modern vehicle architectures requiring higher data throughput and improved noise immunity.

Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-to-pin replacements may include other automotive-grade CAN FD transceivers from manufacturers such as Texas Instruments (e.g., TCAN1042 series) or NXP. Verify that substitute components support the same 5 Mbps data rate, ±70 V bus fault protection, and silent mode functionality before implementation.

Drivers, Receivers, Transceivers FAQ

What is the function of the S pin on the TPT1051Q?

The S pin controls the Silent Mode (also known as listen-only mode). When driven high, the transmitter is disabled, and the device only receives data, preventing a faulty node from blocking the bus.

How does the TPT1051Q handle TXD dominant time-outs?

If the TXD pin remains low for longer than approximately 5 ms, the internal timer disables the transmitter and forces the bus lines to a recessive state to prevent permanent bus locking due to hardware or software failures.

Is the TPT1051Q suitable for CAN FD networks?

Yes, the device is specifically designed for CAN FD networks and supports data rates up to 5 Mbps, offering enhanced timing margins for long and highly loaded networks.
