Product details
Overview
TJA1057GT/3J from NXP Semiconductors is a high-speed CAN transceiver designed for automotive 12 V systems, providing ISO 11898-2:2024 and SAE J2284-1–5 compliant differential transmit/receive capability between a CAN controller and the physical two-wire bus. It supports data rates up to 5 Mbit/s in CAN FD fast phase, features VIO pin for direct 3.3 V microcontroller interfacing, and delivers fail-safe silent mode operation with TXD dominant time-out.
For engineers reviewing the TJA1057GT/3J datasheet, TJA1057GT/3J pinout, TJA1057GT/3J application, or TJA1057GT/3J equivalent, key selection criteria include its AEC-Q100 qualification, 8 kV IEC ESD rating on CANH/CANL, undervoltage detection on both VCC and VIO, thermal shutdown at 185 °C, and SO8 package compatibility with standard automotive PCB layouts.
Technical Context
The TJA1057GT/3J implements the full CAN physical layer per ISO 11898-2:2024 (parameter set B), enabling reliable CAN FD communication up to 5 Mbit/s with guaranteed loop delay symmetry. Its VIO pin decouples I/O level translation from VCC, allowing independent 3.3 V logic interfacing while maintaining 4.5–5.5 V VCC operation.
It integrates fail-safe mechanisms including TXD dominant time-out (0.8–6.5 ms), internal pull-ups on TXD and S pins, undervoltage lockout on VCC (3.5–4.3 V) and VIO (2.1–2.8 V), and overtemperature shutdown at 185 °C. Passive bus behavior when unpowered ensures network integrity during power loss.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 4.5 V to 5.5 V - Enables stable operation across automotive battery voltage fluctuations including cold-crank conditions. |
| VIO Range | 2.91 V to 5.5 V - Supports direct interface with 3.3 V or 5 V microcontrollers without level-shifting circuitry. |
| Max Data Rate | 5 Mbit/s - Certified timing compliance for CAN FD fast phase, enabling higher bandwidth diagnostics and firmware updates. |
| ESD Rating | ±8 kV IEC 61000-4-2 on CANH/CANL - Robust protection against real-world automotive electrostatic discharge events. |
| Undervoltage Thresholds | VCC: 3.5–4.3 V; VIO: 2.1–2.8 V - Ensures graceful bus disengagement before supply collapse disrupts network communication. |
| Thermal Shutdown | 185 °C - Prevents permanent damage during sustained overload or poor heatsinking in engine bay environments. |
| Supply Current (Silent) | 0.1–1.2 mA - Minimizes quiescent power draw in sleep-mode vehicle networks. |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - TXD | Transmit Data Input | Digital input from CAN controller; triggers bus dominant/recessive state; includes internal pull-up to VIO. |
| 2 - GND | Ground Reference | Primary ground return path; must be connected to PCB ground plane for EMC and thermal performance. |
| 3 - VCC | Main Supply Voltage | 4.5–5.5 V power rail; powers internal analog/digital blocks and drivers; monitored for undervoltage lockout. |
| 4 - RXD | Receive Data Output | CMOS-level digital output reflecting bus state; HIGH = recessive, LOW = dominant; internally pulled HIGH in Silent mode. |
| 5 - VIO | I/O Level Adapter Supply | Supplies 2.91–5.5 V to set TXD/RXD/S logic thresholds; enables direct 3.3 V MCU interfacing; not connected in non-VIO variants. |
| 6 - CANL | CAN Bus Low Line | Differential bus terminal; voltage range −42 V to +42 V; protected against automotive transients and ESD. |
| 7 - CANH | CAN Bus High Line | Differential bus terminal; pairs with CANL to form 2-wire physical layer; same transient/ESD ratings as CANL. |
| 8 - S | Silent Mode Control | Active-HIGH input disabling transmitter while preserving receiver function; includes internal pull-up to VIO for fail-safe default. |
Key Features
| Feature | Design Value |
|---|---|
| VIO Pin Support | Enables direct 3.3 V microcontroller interfacing without external level shifters, reducing BOM count and layout complexity. |
| Silent Mode Operation | Disables transmitter while keeping receiver active - prevents faulty nodes from blocking entire CAN network during diagnostics or boot. |

FAQ
What is the maximum data rate supported by the TJA1057GT/3J?
The TJA1057GT/3J supports data rates up to 5 Mbit/s in CAN FD fast phase, with timing parameters guaranteed per ISO 11898-2:2024 parameter set B. This is validated for loop delay symmetry and bit-width deviation, enabling deterministic high-bandwidth communication in automotive networks. The TJA1057GT/3J achieves this while maintaining full backward compatibility with classical CAN 2.0 at 1 Mbit/s.
Does the TJA1057GT/3J require external level-shifting when used with a 3.3 V microcontroller?
No, the TJA1057GT/3J does not require external level-shifting when used with a 3.3 V microcontroller because it includes a dedicated VIO pin that accepts 2.91–5.5 V supplies. When VIO = 3.3 V, the TXD, RXD, and S pins operate at 3.3 V logic levels, ensuring safe and compatible interfacing. The TJA1057GT/3J thus eliminates the need for discrete level translators in mixed-voltage automotive designs.
How does the Silent mode function in the TJA1057GT/3J?
Silent mode in the TJA1057GT/3J is activated by driving pin S HIGH, which disables the transmitter while keeping the receiver fully operational. This allows the node to monitor bus traffic without transmitting, preventing faulty or misconfigured ECUs from disrupting network communication. The TJA1057GT/3J maintains all internal biasing and fail-safe functions in Silent mode, and RXD continues to reflect bus state accurately.
Is the TJA1057GT/3J qualified for automotive use?
Yes, the TJA1057GT/3J is AEC-Q100 qualified (Grade 1: −40 °C to +125 °C ambient, extended to +150 °C virtual junction), certified for automotive applications including under-hood and safety-critical systems. It meets ISO 11898-2:2024, SAE J2284-1–5, and SAE J1939-14 standards, and has been verified for EMC performance per IEC TS 62228 and SAE J2962-2:2019.
What protection features does the TJA1057GT/3J include on its CAN bus pins?
The TJA1057GT/3J provides ±8 kV IEC 61000-4-2 ESD protection on CANH and CANL, ±42 V absolute maximum bus voltage tolerance, and transient immunity per ISO 7637-2 pulse 1/2a/3a/3b. It also features undervoltage detection on VCC and VIO, thermal shutdown at 185 °C, and TXD dominant time-out - collectively ensuring resilience against automotive electrical hazards including load dump, jump start, and ESD events.
