Texas Instruments TCAN1051HGDR

Overview

TCAN1051HGDR from Texas Instruments is a fault-protected, high-speed CAN FD transceiver supporting up to 5 Mbps data rates, ISO 11898-2:2016 and ISO 11898-5:2007 compliance, ±70 V bus fault protection, and operation across –55°C to 150°C junction temperature. It interfaces between a CAN controller and physical bus in automotive powertrain modules, industrial PLCs, and heavy machinery ISOBUS systems.

For engineers reviewing the TCAN1051HGDR datasheet, TCAN1051HGDR pinout, TCAN1051HGDR application, or TCAN1051HGDR equivalent, this page delivers verified electrical specs, SOIC-8 package details, silent mode behavior, thermal shutdown response, and real-world timing margins for CAN FD network design.

Technical Context

The TCAN1051HGDR implements a differential driver/receiver pair with integrated dominant timeout (TXD DTO), undervoltage protection on VCC, and thermal shutdown at 170°C. Its "H" variant provides ±70 V bus fault tolerance, while the "G" suffix enables 5 Mbps CAN FD operation-distinct from base 2 Mbps variants.

It supports dual-supply I/O level shifting only in "V"-suffixed versions; TCAN1051HGDR uses single 5 V supply (VCC) and drives RXD referenced to VCC. Silent mode (S = HIGH) disables driver output while preserving receiver functionality, enabling non-intrusive bus monitoring.

Key Specifications

Pinout & Package

FAQ

What is the maximum CAN FD data rate supported by the TCAN1051HGDR?

The TCAN1051HGDR supports up to 5 Mbps CAN FD data rate, enabled by its "G" suffix designation. This exceeds the 2 Mbps capability of base TCAN1051 variants and is validated per ISO 11898-2:2016 timing requirements. The TCAN1051HGDR achieves this with symmetrical propagation delays and fast loop times-critical for maintaining timing margin in electrically noisy, loaded networks.

Does the TCAN1051HGDR include thermal shutdown protection?

Yes, the TCAN1051HGDR includes thermal shutdown protection that activates at 170°C junction temperature, with 5°C hysteresis. This feature prevents permanent damage during sustained bus short-circuit events. Unlike simpler transceivers, TCAN1051HGDR resumes normal operation automatically after cooling below 165°C-no reset or power cycle required. The TCAN1051HGDR's thermal metrics (RθJA = 105.8°C/W) are published for accurate PCB thermal design.

How does silent mode function on the TCAN1051HGDR?

Silent mode on the TCAN1051HGDR is activated by driving the S pin (Pin 8) HIGH. In this state, the driver output is disabled-CANH and CANL remain in recessive-while the receiver remains fully operational. This allows non-intrusive bus monitoring during system diagnostics or safety validation. The TCAN1051HGDR maintains full RXD output functionality and common-mode range (±30 V) in silent mode, with no change to power consumption or timing characteristics.

What package type is used for the TCAN1051HGDR?

The TCAN1051HGDR is packaged in an 8-pin SOIC (D) body measuring 4.90 mm × 3.91 mm, with gull-wing leads. This package is distinct from the VSON-8 (DRB) variant and is optimized for compatibility with standard surface-mount assembly processes, automated optical inspection, and thermal performance in convection-cooled industrial environments. The TCAN1051HGDR's SOIC-8 footprint matches legacy CAN transceivers for drop-in replacement where 5 Mbps and ±70 V protection are needed.

Is the TCAN1051HGDR compatible with 3.3 V microcontrollers?

The TCAN1051HGDR accepts 5 V logic levels on TXD and S inputs and drives RXD at VCC (5 V), so direct interfacing with 3.3 V MCUs requires level translation on TXD and RXD lines. Unlike "V"-suffix variants (e.g., TCAN1051HGV), the TCAN1051HGDR lacks a dedicated VIO pin and does not support 3.3 V I/O level shifting. For native 3.3 V MCU compatibility, consider TCAN1051HGV instead-but note that TCAN1051HGDR retains superior 5 Mbps timing and identical ±70 V fault protection.
