Product details
Overview
TLE8262EXUMA1 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 27 V supply, and featuring integrated wake-up via bus activity detection. It is used in automotive body control modules for reliable communication between ECUs over harsh vehicle networks.
For engineers reviewing the TLE8262EXUMA1 datasheet, TLE8262EXUMA1 pinout, TLE8262EXUMA1 application, or TLE8262EXUMA1 equivalent, key selection criteria include bus fault protection level (±70 V), common-mode voltage range (−2 V to +14 V), thermal shutdown behavior, and compatibility with 3.3 V or 5 V controller I/O logic levels.
Technical Context
The TLE8262EXUMA1 implements a fully isolated physical layer interface between a CAN controller and the differential CAN bus. It integrates dominant timeout protection, slope control for EMI reduction, and a high-immunity receiver with fail-safe RXD output during bus faults.
Its VIO pin enables independent logic-level supply (1.8 V to 5.5 V), decoupling controller voltage domain from bus-side power. The device supports silent mode and standby mode with ultra-low current consumption (<15 µA) and wake-up capability via CANH/CANL edge detection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | Up to 5 Mbps - enables high-bandwidth diagnostics and real-time actuator control in modern ADAS domains. |
| Supply Voltage (VCC) | 4.5 V to 27 V - accommodates wide automotive battery variation including cold-crank (4.5 V) and load-dump (27 V) conditions. |
| Bus Fault Protection | ±70 V - protects against ISO 7637-2 pulse 5a/b transients without external TVS diodes. |
| Common-Mode Range | −2 V to +14 V - ensures robust operation under ground offset in distributed vehicle architectures. |
| VIO Supply Range | 1.8 V to 5.5 V - allows direct interfacing with 3.3 V or 5 V microcontrollers without level shifters. |
| Standby Current | <15 µA - supports low-power ECU sleep modes while retaining bus-wake capability. |
Pinout & Package
Package: PG-DSO-36 (36-pin exposed pad SOIC variant, 1.27 mm pitch, RoHS-compliant).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Main supply input | Power rail for bus-side circuitry; requires local 100 nF decoupling. |
| VIO | Logic I/O supply | Provides voltage reference for TXD/RXD pins; decouples controller domain. |
| TXD | Transmit input | CMOS-compatible digital input from CAN controller; active-high logic. |
| RXD | Receive output | CMOS output reflecting bus state; held dominant during bus fault. |
| STB | Standby control | Active-low enable; pulls device into ultra-low-current standby when high. |
| WAKE | Wake-up status output | Open-drain flag indicating bus activity detected during standby. |
| CANH / CANL | Differential bus terminals | Connect directly to twisted-pair CAN bus; integrated termination not included. |
Key Features
| Feature | Design Value |
|---|---|
| ISO 11898-2:2016 compliance | Ensures interoperability with all standard high-speed CAN networks including OEM-specific implementations. |
| Dominant timeout protection | Prevents bus lock-up by forcing recessive state if TXD remains dominant > 1.2 ms. |
| Slope control selection | Configurable via SLOPE pin to adjust edge rate for optimized EMI vs. speed trade-off. |
| Thermal shutdown | Disables driver stage at >175 °C junction temperature; auto-recovers after cooldown. |
| Fail-safe RXD | Outputs dominant logic low during bus short-to-battery or open-circuit faults, signaling error to controller. |
Applications
| Body Control Module (BCM) | Door Control Unit (DCU) |
|---|---|
Use Scenario: Centralized management of lighting, windows, locks, and mirrors across vehicle doors and cabin. IC Role / Device Role / Timing Role: Physical-layer CAN interface enabling bidirectional command/response messaging between BCM MCU and distributed door nodes. Use Value: ±70 V bus fault tolerance prevents latch-up during jump-start events; VIO flexibility simplifies integration with mixed-voltage MCU platforms. | Use Scenario: Local control of window lift motors, mirror actuators, and anti-pinch sensors within each door assembly. IC Role / Device Role / Timing Role: Robust CAN PHY transceiver handling intermittent bus disconnection during door removal/maintenance. Use Value: Standby current <15 µA extends battery life in parked vehicle monitoring; wake-on-bus activity eliminates need for separate wake lines. |
| Seat Control Module | Roof Module (Sunroof/Blind) |
Use Scenario: Positioning and memory control of multi-motor electric seats with feedback from potentiometers and Hall sensors. IC Role / Device Role / Timing Role: High-integrity CAN transceiver ensuring deterministic latency (<150 ns propagation delay) for seat position updates. Use Value: −2 V to +14 V common-mode range maintains communication despite large ground offsets between chassis and seat rails. | Use Scenario: Coordinated control of sunroof glass/slats and interior blinds using shared CAN infrastructure. IC Role / Device Role / Timing Role: Bus interface with integrated dominant timeout, preventing bus hang during motor stall-induced TXD assertion. Use Value: Slope control configuration reduces radiated emissions in proximity to AM/FM antennas without sacrificing 500 kbps operational speed. |
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/3 | Lower bus fault protection (±60 V); no VIO pin - fixed 3.3 V or 5 V logic interface. | Lacks independent VIO, limiting use with mixed-voltage controllers; suitable for cost-sensitive entry-level BCMs. | Select when system uses only 3.3 V or 5 V MCUs and ISO 7637-2 pulse 5a margin is ≥10 V lower than required. |
| ST TLE6250G | Legacy ISO 11898-2:2003 compliant; max 1 Mbps data rate; no slope control or wake-up output. | Not suitable for 2+ Mbps diagnostics or low-power wake-on-bus architectures. | Only consider for brownfield designs requiring backward compatibility with legacy CAN networks. |
Compared with TJA1044GT/3 and TLE6250G, the TLE8262EXUMA1 provides superior bus fault resilience, flexible logic interfacing, and full support for modern low-power, high-speed automotive networking requirements - making it optimal for next-generation body electronics.

FAQ
What is the maximum common-mode voltage the TLE8262EXUMA1 can tolerate during normal operation?
The TLE8262EXUMA1 supports a common-mode voltage range of −2 V to +14 V per ISO 11898-2:2016. This allows reliable operation under ground potential differences typical in vehicle architectures, such as between chassis and door modules, without signal corruption or false dominant detection.
Does the TLE8262EXUMA1 require external termination resistors on the CAN bus?
No, the TLE8262EXUMA1 does not integrate bus termination. A 120 Ω resistor must be placed externally between CANH and CANL at each bus end. The device's output stage is designed to drive standard 120 Ω terminated lines with controlled edge rates selectable via the SLOPE pin.
How does the dominant timeout function protect the CAN network?
The dominant timeout circuit disables the driver output if TXD remains high for longer than 1.2 ms, forcing RXD to recessive. This prevents a single faulty node from holding the bus dominant and blocking communication for other ECUs - a critical safety feature in distributed automotive networks.
Can the TLE8262EXUMA1 operate with a 1.8 V CAN controller I/O supply?
Yes - the VIO pin accepts 1.8 V to 5.5 V, allowing direct connection to 1.8 V logic controllers. RXD output swing and TXD input thresholds are referenced to VIO, eliminating level-shifting components and reducing PCB area and BOM cost in low-voltage MCU designs.
