Product details
Overview
TCAN1051GVDRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive CAN FD transceiver supporting up to 5 Mbps data rate, ±58 V bus fault protection, and dual-supply I/O level shifting (VCC/VIO). It operates from –40°C to 125°C ambient, features 110 ns typical loop delay, and meets ISO 11898-2:2016 and ISO 11898-5:2007 standards for use in engine control units and ADAS domain controllers.
For engineers reviewing the TCAN1051GVDRQ1 datasheet, TCAN1051GVDRQ1 pinout, TCAN1051GVDRQ1 application, or TCAN1051GVDRQ1 equivalent, this page delivers verified electrical specs, SOIC-8 pin mapping, functional safety documentation support, silent mode operation, and real-world EMC performance data per SAE J2962-2 and IEC 62228-3.
Technical Context
The TCAN1051GVDRQ1 implements a high-speed differential driver/receiver pair compliant with ISO 11898-2:2016 physical layer requirements, with integrated dominant time-out (DTO) limiting TXD low-time to ≥100 µs at 10 kbps and thermal shutdown at 170°C. Its dual-supply architecture separates VCC (5 V transceiver core) from VIO (2.8–5.5 V logic interface), enabling direct interfacing with 3.3 V or 5 V MCUs without external level shifters.
It supports both classic CAN and CAN FD protocols, with "G" suffix denoting 5 Mbps capability and "V" suffix enabling I/O voltage translation. The device enters high-impedance passive state when unpowered, preserving bus integrity during power sequencing, and includes robust protection against ESD (±15 kV IEC), bus faults, and undervoltage on both supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Data Rate | 5 Mbps - Enables high-bandwidth CAN FD communication in ADAS sensor fusion and gateway applications. |
| Bus Fault Protection | ±58 V - Protects against load-dump and jump-start transients in 12 V automotive systems without external clamping. |
| Loop Delay | 110 ns typical - Provides tight timing margin for synchronization in multi-node CAN FD networks operating at 2–5 Mbps. |
| VIO Supply Range | 2.8 V to 5.5 V - Allows direct connection to 3.3 V microcontrollers while maintaining full RXD output swing and input threshold compatibility. |
| Common-Mode Range | ±30 V - Ensures reliable reception under severe ground offset conditions in chassis-mounted ECUs. |
| ESD Protection | ±15 kV IEC 61000-4-2 contact discharge - Meets stringent automotive system-level ESD immunity requirements without external TVS diodes. |
| Thermal Shutdown | 170°C with 5°C hysteresis - Prevents permanent damage during sustained bus short-circuit events in enclosed junction boxes. |
Pinout & Package
TCAN1051GVDRQ1 is supplied in an 8-pin SOIC package (4.90 mm × 3.91 mm body size) with standard lead pitch and gull-wing leads suitable for automated optical inspection and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - TXD | Digital input | CMOS-compatible CAN transmit data input; accepts 0.3×VIO/0.7×VIO thresholds for 3.3 V or 5 V MCU drive. |
| 2 - GND | Ground reference | Primary return path for VCC, VIO, and bus circuitry; must be connected to low-impedance system ground plane. |
| 3 - VCC | Power supply | 5 V ±10% supply for transceiver core; undervoltage lockout triggers at 3.8–4.2 V to prevent metastable bus states. |
| 4 - RXD | Digital output | CMOS output driven to VIO level; sinks/source ±2 mA; high-impedance when unpowered. |
| 5 - VIO | Power supply | I/O level-shifting supply (2.8–5.5 V); sets RXD output voltage and TXD/RXD input thresholds; UVLO active below 1.3 V. |
| 6 - CANL | Bus I/O | Low-side differential CAN bus terminal; internally biased; withstands ±58 V fault voltage relative to GND. |
| 7 - CANH | Bus I/O | High-side differential CAN bus terminal; complements CANL; maintains symmetry within ±0.4 V DC offset. |
| 8 - S | Digital input | Silent mode enable (active-high); disables driver output while preserving receiver functionality for non-intrusive bus monitoring. |
Key Features
| Feature | Design Value |
|---|---|
| 5 Mbps CAN FD support | Enables faster firmware updates and sensor data streaming in next-gen vehicle architectures without protocol stack changes. |
| Dual-supply I/O level shifting | VIO pin allows independent 3.3 V logic interface while VCC powers 5 V bus driver-eliminates external level translators in mixed-voltage designs. |
| Silent (listen-only) mode | Pin 8 control enables bus monitoring without affecting network arbitration-critical for diagnostic loggers and security gateways. |
| ±58 V bus fault tolerance | Withstands automotive load-dump and reverse-battery conditions without latch-up or degradation-reduces need for external protection. |
| IEC 61000-4-2 ±15 kV ESD | Passes system-level ESD testing per ISO 10605 without board-level TVS components-lowers BOM cost and layout complexity. |

FAQ
What is the maximum data rate supported by the TCAN1051GVDRQ1?
The TCAN1051GVDRQ1 supports up to 5 Mbps for CAN FD operation, as confirmed by its "G" suffix designation and validated switching characteristics in the official datasheet. This enables high-throughput messaging for firmware updates and sensor data aggregation in modern automotive networks. The TCAN1051GVDRQ1 maintains full compliance with ISO 11898-2:2016 at this rate, with symmetrical propagation delays and tight loop timing.
Does the TCAN1051GVDRQ1 support 3.3 V microcontrollers?
Yes, the TCAN1051GVDRQ1 supports 3.3 V microcontrollers via its dedicated VIO pin, which sets input thresholds and RXD output levels independently of the 5 V VCC supply. When VIO = 3.3 V, the TCAN1051GVDRQ1 accepts 3.3 V logic inputs and drives RXD to 3.3 V levels-enabling direct interface without external level shifters.
What protection features does the TCAN1051GVDRQ1 include?
The TCAN1051GVDRQ1 includes ±58 V bus fault protection, ±15 kV IEC 61000-4-2 ESD protection on CANH/CANL, undervoltage lockout on both VCC and VIO, driver dominant time-out (≥100 µs at 10 kbps), and thermal shutdown at 170°C. These features ensure robust operation in harsh automotive environments without requiring additional protection circuitry.
How does silent mode function on the TCAN1051GVDRQ1?
Silent mode on the TCAN1051GVDRQ1 is activated by driving the S pin (Pin 8) high, which disables the transmitter driver while keeping the receiver fully operational. This allows non-intrusive bus monitoring-essential for diagnostic tools and security gateways. The TCAN1051GVDRQ1 maintains full RXD output functionality and bus fault detection during silent mode.
Is the TCAN1051GVDRQ1 qualified for automotive applications?
Yes, the TCAN1051GVDRQ1 is AEC-Q100 qualified for automotive applications, rated for Grade 1 temperature range (–40°C to +125°C ambient), with HBM ESD rating of ±16 kV and CDM rating of ±1500 V. It meets ISO 11898-2:2016 and ISO 11898-5:2007 standards and includes functional safety documentation to support ISO 26262 system development.
