Product details
Overview
TLE7259GT 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, and featuring ±58 V bus fault protection. It serves as the physical layer interface between a CAN controller and the differential CAN bus in automotive body electronics modules.
For engineers reviewing the TLE7259GT datasheet, TLE7259GT pinout, TLE7259GT application, or TLE7259GT equivalent, key selection criteria include bus fault tolerance, common-mode voltage range (−27 V to +40 V), silent mode functionality, thermal shutdown behavior, and compatibility with 3.3 V or 5 V CAN controllers.
Technical Context
The TLE7259GT implements a fully integrated differential driver and receiver with dominant timeout protection and slope control for EMI reduction. Its RXD output is logic-compatible with both 3.3 V and 5 V microcontrollers, and it supports wake-up via bus activity while in standby mode.
It features a split supply architecture: VCC powers the logic side (2.7–5.5 V), while VIO enables independent I/O voltage setting (1.7–5.5 V). The device includes undervoltage lockout (UVLO) on both supplies and thermal shutdown with automatic recovery.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | Up to 5 Mbps - enables high-speed CAN FD physical layer communication without external signal conditioning |
| Bus Fault Protection | ±58 V - protects against load dump, jump-start, and battery reverse connection in 12 V automotive systems |
| Common-Mode Range | −27 V to +40 V - ensures robust operation during severe ground bounce or battery disconnect transients |
| VIO Supply Range | 1.7 V to 5.5 V - allows direct interfacing with low-voltage CAN controllers without level shifters |
| Standby Current | ≤ 15 µA - supports ultra-low-power wake-on-CAN functionality in always-on vehicle domains |
| Thermal Shutdown | Activated at >170 °C, auto-recovery - prevents permanent damage during sustained bus short-circuit conditions |
Pinout & Package
Package: PG-DSO-8 (8-pin exposed pad SOIC, 150 mil width, RoHS-compliant, moisture sensitivity level 3).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Logic supply input | Powers internal logic; requires local 100 nF decoupling to GND |
| GND | Ground reference | Common return for logic and bus-side circuitry; connects to exposed thermal pad |
| VIO | I/O supply input | Sets RXD output voltage level and TXD input threshold; independent of VCC |
| TXD | Transmit data input | CMOS-compatible input driving differential bus output; active-high logic |
| RXD | Receive data output | CMOS output reflecting bus state; high = recessive, low = dominant |
| STB | Standby mode control | Active-low enable; pulls RXD high-impedance and disables driver when asserted |
| EN | Enable control | Active-high; must be high for normal operation; tied to VCC if unused |
| VSUP | Bus supply monitor | Open-drain fault indicator; pulled low during UVLO or thermal shutdown |
Key Features
| Feature | Design Value |
|---|---|
| ISO 11898-2:2016 compliance | Guarantees interoperability with other high-speed CAN nodes in automotive ECUs |
| Dominant timeout protection | Prevents bus lock-up by forcing recessive state after 8 bit times of continuous dominant TXD |
| Slope control selection | Configurable via external resistor to meet CISPR 25 Class 5 emission limits |
| Wake-up via bus activity | Generates local interrupt on bus edge detection while in standby, reducing system power |
| Split VCC/VIO supplies | Enables mixed-voltage system integration without external level translators |

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 TJA1044GT | Lower bus fault protection (±42 V); no VSUP pin; fixed 5 V VIO only | Lacks bus supply monitoring and flexible I/O voltage; suited for cost-sensitive non-critical nodes | Select when system-level fault protection is managed externally and VIO matching is fixed |
| ST TLE6250G | Legacy ISO 11898-2:2003 compliant; 1 Mbps max; no slope control or dominant timeout | Designed for legacy CAN networks; lacks modern EMI and safety features | Choose only for backward compatibility in existing 1 Mbps designs with no upgrade path |
Compared with TJA1044GT and TLE6250G, the TLE7259GT provides superior fault resilience, programmable slew rate, and dual-supply flexibility-critical for next-generation 5 Mbps body domain ECUs requiring long-term design-in stability and OEM compliance.

FAQ
What is the maximum common-mode voltage the TLE7259GT can withstand during transient conditions?
The TLE7259GT supports a guaranteed common-mode voltage range of −27 V to +40 V under steady-state and transient conditions, validated per ISO 11898-2:2016 Annex C test pulses. This enables reliable operation during battery disconnection, ground bounce, and alternator load dump scenarios in 12 V automotive systems without external protection components.
Does the TLE7259GT require an external resistor for slope control, and how is it configured?
Yes, slope control is configured using an external resistor (RSLOPE) connected between the SLOPE pin and GND. Values from 10 kΩ to 100 kΩ set different slew rates to meet CISPR 25 Class 5 radiated emission limits. No resistor yields fastest edge rate; 100 kΩ yields slowest, lowest EMI configuration. Resistor value is not internally trimmed and must be selected per board-level EMC testing.
Can the TLE7259GT interface directly with a 3.3 V CAN controller without level shifting?
Yes, the TLE7259GT supports independent VIO supply (1.7 V to 5.5 V), allowing direct connection to 3.3 V CAN controllers. When VIO = 3.3 V, RXD outputs CMOS levels compatible with 3.3 V logic thresholds, and TXD accepts 3.3 V logic inputs. VCC may remain at 5 V for optimal internal logic performance, eliminating need for external level translators.
How does the STB (standby) pin behave during low-power operation, and what is its effect on RXD?
When STB is pulled low, the TLE7259GT enters standby mode: the bus driver is disabled, RXD goes to high-impedance (not driven), and quiescent current drops to ≤15 µA. RXD remains inactive until STB is deasserted; no bus activity is detected or forwarded in this state. A pull-up resistor on STB is recommended to ensure defined startup behavior.
