Product details
Overview
TJA1441ATK/0Z from NXP Semiconductors is a high-speed CAN FD transceiver implementing ISO 11898-2:2016 and SAE J2284-1–5, supporting data rates up to 5 Mbit/s, operating from 4.5 V to 5.5 V supply, qualified to AEC-Q100 Grade 1, and housed in an HVSON8 (3.0 mm × 3.0 mm) package for automotive body control modules.
For engineers reviewing the TJA1441ATK/0Z datasheet, TJA1441ATK/0Z pinout, TJA1441ATK/0Z application, or TJA1441ATK/0Z equivalent, this page delivers verified electrical parameters, fail-safe mode behavior, bus protection specs, thermal resistance (Rth(j-a) = 57 K/W), and confirmed pin-compatible alternatives for retrofitting legacy CAN designs.
Technical Context
The TJA1441ATK/0Z implements a differential CAN physical layer with integrated TXD dominant time-out, undervoltage detection on both VCC and VIO pins, and internal pull-ups on all digital inputs (TXD, S, RXD). It supports three defined operating modes-Normal, Silent, and Off-with mode transitions governed by voltage thresholds and timing recovery windows (trec(uv), tstartup).
Its fail-safe architecture includes overtemperature shutdown (Tj(sd) = 180–200 °C), ESD protection (±8 kV IEC 61000-4-2 on CANH/CANL), and bus fault tolerance (−36 V to +40 V), while maintaining low EME and high EMI immunity per automotive EMC standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage (VCC) | 4.5 V to 5.5 V - ensures compatibility with standard 5 V automotive microcontrollers and stable operation across battery voltage fluctuations. |
| Data Rate Support | Up to 5 Mbit/s - enables full CAN FD fast-phase communication for high-bandwidth ECUs like ADAS gateways and powertrain controllers. |
| Undervoltage Detection (Vuvd) | 4.0 V to 4.5 V on VCC - triggers automatic transition to Off mode before logic corruption occurs, preventing undefined bus states during brownout. |
| Thermal Resistance (Rth(j-a)) | 57 K/W (HVSON8) - allows reliable operation at 150 °C ambient in engine bay applications without external heatsinking. |
| ESD Protection | ±8 kV IEC 61000-4-2 on CANH/CANL - meets automotive system-level ESD robustness requirements without additional TVS diodes. |
| Operating Temperature | −40 °C to +150 °C - supports placement in under-hood and chassis-mounted modules per AEC-Q100 Grade 1 qualification. |
| Bus Fault Tolerance | −36 V to +40 V on CANH/CANL - withstands load dump, jump-start, and reverse-battery conditions per ISO 7637-2. |
Pinout & Package
HVSON8 package (3.0 mm × 3.0 mm, 0.85 mm height, leadless, thermal pad exposed); optimized for automated optical inspection (AOI) and high-density PCB layouts in automotive ECUs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - TXD | Transmit Data Input | Digital input from CAN controller; initiates bus transmission when driven LOW; features internal 20–80 kΩ pull-up to VIO for fail-safe HIGH default. |
| 2 - GND | Ground Reference | Primary ground connection; die ground tied to both pin 2 and exposed center pad-both must be soldered to PCB ground for thermal and EMI performance. |
| 3 - VCC | Main Supply Input | 5 V supply rail; powers core transceiver circuitry; monitored for undervoltage detection (Vuvd = 4.0–4.5 V) and switch-off (Vuvd(swoff) = 2.65–2.95 V). |
| 4 - RXD | Receive Data Output | Digital output to CAN controller; reflects bus state with <115 ns propagation delay; level-shifted to VIO in TJA1441A variant. |
| 5 - VIO | I/O Level Adapter Supply | Supplies 2.95–5.5 V to set TXD/RXD/S logic levels-enables direct interface with 3.3 V or 5 V microcontrollers without level shifters. |
| 6 - CANL | CAN Bus Low Line | Analog bidirectional bus terminal; internally biased to VCC/2 in Silent mode; withstands −36 V to +40 V fault voltages. |
| 7 - CANH | CAN Bus High Line | Analog bidirectional bus terminal; differential pair with CANL; supports dominant output swing of 2.75–4.5 V (CANH) and 0.5–2.25 V (CANL). |
| 8 - S | Silent Mode Control | Active-HIGH digital input; disables transmitter while keeping receiver active-used for node diagnosis and failure containment without network disruption. |
Key Features
| Feature | Design Value |
|---|---|
| ISO 11898-2:2016 & SAE J2284-1–5 compliance | Guarantees interoperability with all high-speed Classical CAN and CAN FD transceivers in automotive networks. |
| VIO-supplied I/O level adaptation | Enables direct connection to 3.3 V or 5 V microcontrollers without external level-shifting components or design rework. |
| Silent mode with active receiver | Allows real-time bus monitoring while disabling transmitter-critical for diagnostic logging and fault isolation in multi-node systems. |
| TXD dominant time-out (tto(dom)TXD) | Prevents permanent bus dominance due to MCU lockup; automatically releases bus to recessive after timeout, preserving network availability. |
| Gap-free undervoltage behavior | Defined state transitions across entire VCC/VIO range-including hysteresis (50 mV) and separate switch-off threshold-eliminates metastability during power ramp-up/down. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed CAN FD transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TJA1057T/3 | SO8 only; no VIO pin; supports only 5 V I/O; lacks Silent mode pin (S) on SO8 variant; lower ESD rating (±6 kV). | Requires external level-shifting for 3.3 V MCUs; no dedicated Silent mode control-relies on software-controlled TXD gating. | Select when retrofitting legacy SO8 footprints without VIO or Silent mode requirements; verify ESD margin in harsh environments. |
| MCP2562FD-H/SN | 5 V-only supply; no VIO; supports CAN FD up to 8 Mbit/s; higher ICC in Normal mode (70 mA typ); different pinout (RXD/TXD swapped). | Designed for higher-speed industrial CAN FD; not AEC-Q100 qualified; requires PCB layout revision due to non-pin-compatible pinout. | Select for non-automotive CAN FD applications needing >5 Mbit/s; avoid for automotive retrofits due to pinout mismatch and qualification gap. |
Compared with TJA1057T/3 and MCP2562FD-H/SN, the TJA1441ATK/0Z uniquely combines AEC-Q100 Grade 1 qualification, HVSON8 thermal performance, VIO-based 3.3 V/5 V compatibility, and hardware-enabled Silent mode-making it the only drop-in solution for upgrading existing TJA1051-based designs to CAN FD with zero layout changes.

FAQ
What is the primary function of the TJA1441ATK/0Z in a CAN FD network?
The TJA1441ATK/0Z serves as a high-speed physical layer transceiver that interfaces a CAN FD protocol controller with the two-wire CAN bus. It converts digital TXD signals into differential bus voltages (CANH/CANL) and recovers bus data into RXD output, supporting data rates up to 5 Mbit/s while complying with ISO 11898-2:2016 and SAE J2284-1–5. Its role is critical for noise-immune, deterministic communication in automotive ECUs.
Does the TJA1441ATK/0Z support 3.3 V microcontrollers directly?
Yes, the TJA1441ATK/0Z supports direct interfacing with 3.3 V microcontrollers via its dedicated VIO pin (pin 5), which sets the logic voltage levels for TXD, RXD, and S inputs. When VIO is supplied with 3.3 V, all I/O signals operate at 3.3 V logic thresholds-eliminating the need for external level shifters and simplifying integration with modern low-voltage MCUs.
How does Silent mode operate on the TJA1441ATK/0Z, and what is its practical use?
Silent mode on the TJA1441ATK/0Z is activated by driving pin S (pin 8) HIGH, which disables the transmitter while keeping the receiver fully operational. This allows the node to monitor bus traffic without transmitting, enabling diagnostic logging, firmware validation, and failure containment-especially valuable during ECU updates or when isolating faulty nodes in multi-controller networks without disrupting overall CAN communication.
What protection features does the TJA1441ATK/0Z include for automotive environments?
The TJA1441ATK/0Z includes ±8 kV IEC 61000-4-2 ESD protection on CANH/CANL, bus fault tolerance from −36 V to +40 V, TXD dominant time-out to prevent bus lockup, undervoltage detection with hysteresis (50 mV), and overtemperature shutdown (180–200 °C). These features collectively meet stringent automotive EMC and reliability requirements without external protection components.
Is the TJA1441ATK/0Z pin-compatible with legacy NXP transceivers like the TJA1051?
Yes, the TJA1441ATK/0Z is explicitly designed as a pin-compatible replacement for the TJA1051 and TJA1057 in HVSON8 footprint. It retains identical pin numbering, electrical interface, and functional behavior-including Normal and Silent modes-while adding CAN FD support, VIO flexibility, and enhanced protection. No PCB or firmware changes are required for retrofitting.
