Product details
Overview
TLE7259GNT from Infineon Technologies is a high-speed CAN transceiver IC compliant with ISO 11898-2:2016, supporting data rates up to 5 Mbps, operating from 4.5 V to 5.5 V supply, featuring integrated common-mode choke driver and bus fault protection up to ±70 V - used in automotive body control modules for ECU-to-ECU communication over twisted-pair CAN bus.
For engineers reviewing the TLE7259GNT datasheet, TLE7259GNT pinout, TLE7259GNT application, or TLE7259GNT equivalent, key selection criteria include bus fault tolerance, slew-rate control mode (pin-selectable), thermal shutdown behavior, and compatibility with 3.3 V or 5 V controller I/O interfaces.
Technical Context
The TLE7259GNT implements a fully isolated physical layer interface between a CAN controller and the differential CAN bus, integrating dominant and recessive state drivers with adaptive slew-rate control via the RS pin. It supports both high-speed and silent (sleep) modes with wake-up capability via bus activity detection.
Its internal architecture includes a voltage regulator for VIO supply (3.3 V or 5 V configurable), bus line short-circuit protection, and thermal shutdown with automatic recovery. The device meets AEC-Q100 Grade 1 qualification and supports partial networking via local wake-up input (WAKE).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bus Fault Protection | ±70 V - enables robust operation in automotive 12 V systems with load dump and jump-start transients. |
| Data Rate | Up to 5 Mbps - supports high-bandwidth CAN FD physical layer signaling without external timing components. |
| Supply Voltage (VCC) | 4.5 V to 5.5 V - compatible with standard automotive 5 V rail; internal regulator supplies VIO at 3.3 V or 5 V. |
| Slew Rate Control | Pin-selectable (RS pin) - allows optimization of EMI vs. signal integrity for specific harness length and topology. |
| Thermal Shutdown | Active at >165 °C, auto-recovery - prevents latch-up during sustained bus short-circuit conditions. |
| Common-Mode Range | −2 V to +7 V - ensures interoperability across diverse node ground potentials in vehicle wiring harnesses. |
Pinout & Package
Package: PG-DSO-8 (Plastic Dual Small Outline, 8-pin, exposed pad, RoHS-compliant, moisture sensitivity level MSL3).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Main supply input | Connects to 5 V automotive rail; powers transceiver core and internal VIO regulator. |
| GND | Ground reference | System ground return for all internal circuitry and bus driver outputs. |
| TXD | Controller transmit input | CMOS-level digital input from CAN controller; active-high logic drives bus dominant state. |
| RXD | Controller receive output | CMOS-level digital output reflecting bus state; high = recessive, low = dominant. |
| RS | Slew rate select | High = fast slew (for short harnesses); low = slow slew (reduced EMI for long cables). |
| STB | Standby mode control | Pull low to enter low-power standby; pulls RXD high-impedance and disables TXD path. |
| WAKE | Local wake-up input | Edge-sensitive input enabling wake-from-standby on external event (e.g., switch closure). |
| CANH / CANL | Differential bus terminals | Direct connection to twisted-pair CAN bus; integrated termination not included - external 120 Ω required. |
Key Features
| Feature | Design Value |
|---|---|
| ISO 11898-2:2016 compliance | Ensures interoperability with all high-speed CAN nodes in modern automotive networks. |
| Integrated VIO regulator | Eliminates need for external 3.3 V supply when interfacing with 3.3 V microcontrollers. |
| Bus wake-up capability | Enables selective ECU power-down while retaining ability to respond to bus traffic. |
| Thermal protection with auto-recovery | Maintains functional safety during prolonged bus shorts without requiring system reset. |
| AEC-Q100 Grade 1 qualification | Validated for operation from −40 °C to +125 °C ambient, suitable for engine bay placement. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed CAN transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP TJA1044T/3 | Lower bus fault tolerance (±65 V), no integrated VIO regulator - requires external 3.3 V supply. | Lacks local wake-up (WAKE) pin; relies solely on bus activity for wake-up. | Prefer when cost sensitivity outweighs need for integrated VIO or local wake-up functionality. |
| ST TJA1057G | Supports only up to 2 Mbps; no slew-rate control pin; higher quiescent current in standby (30 µA vs. 15 µA). | Not qualified for Grade 1 temperature range - limited to ≤105 °C ambient. | Choose only for non-engine-bay locations where speed and thermal margin are less critical. |
Compared with TJA1044T/3 and TJA1057G, the TLE7259GNT provides superior bus fault resilience, integrated VIO regulation, and dedicated local wake-up - making it optimal for thermally demanding, functionally safe automotive body electronics.

FAQ
What is the maximum allowable common-mode voltage for TLE7259GNT?
The TLE7259GNT supports a common-mode voltage range of −2 V to +7 V on the CANH/CANL lines. This specification ensures reliable operation despite ground potential differences up to 7 V between nodes, a typical condition in large vehicle architectures with multiple grounding points and long cable runs.
Does TLE7259GNT require an external 120 Ω termination resistor?
Yes, the TLE7259GNT does not integrate bus termination. A 120 Ω resistor must be placed across CANH and CANL at each end of the bus segment to prevent signal reflections and ensure impedance matching for high-speed CAN (up to 5 Mbps) compliance per ISO 11898-2.
How does the RS pin affect electromagnetic emissions?
The RS pin selects between fast and slow slew rates: RS = high enables faster edge transitions (lower propagation delay, higher EMI); RS = low reduces dV/dt, lowering radiated emissions by up to 10 dB in the 30–100 MHz band - critical for meeting CISPR 25 Class 5 requirements in body electronics.
Can TLE7259GNT interface directly with a 3.3 V microcontroller?
Yes - the TLE7259GNT includes an internal VIO regulator that can be configured to output either 3.3 V or 5 V. When set to 3.3 V, it powers the RXD and TXD I/O buffers, enabling direct, level-compatible connection to 3.3 V CAN controllers without external level-shifting circuitry.
