Product details
Overview
TLE6251DSNTMA1 from Infineon Technologies is a high-speed CAN transceiver in PG-DSO-8 package, implementing ISO/DIS 11898-compliant differential bus interface with 1 Mbaud data rate, ±40 V common-mode range, and remote wake-up via CAN bus in standby mode; used as physical layer interface between CAN controller and bus lines in automotive body control modules.
For engineers reviewing the TLE6251DSNTMA1 datasheet, TLE6251DSNTMA1 pinout, TLE6251DSNTMA1 application, or TLE6251DSNTMA1 equivalent, key selection criteria include bus wake-up capability, split termination support, STB-controlled mode switching, overtemperature protection, and AEC-Q100 qualification for 12 V/24 V automotive networks.
Technical Context
The TLE6251DSNTMA1 integrates driver and receiver stages with Smart Power Technology SPT®, enabling bipolar/CMOS logic and DMOS power devices on one die. It supports two operational modes-normal (active TX/RX) and standby (ultra-low current, wake-up enabled)-controlled by the STB pin with internal pull-up.
Its wake-up logic detects dominant/recessive transitions on CANH/CANL and asserts RxD level change without bus loading; split termination (SPLIT pin) stabilizes recessive common-mode voltage, while TxD time-out prevents bus lockup during stuck-dominant faults.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | Up to 1 Mbaud - enables real-time communication in high-speed automotive CAN FD precursor networks. |
| Common-Mode Range | ±40 V - ensures robust operation under severe automotive EMI and load-dump conditions. |
| Supply Voltage | 5 V (VCC) - compatible with standard microcontroller I/O domains and requires local 100 nF decoupling. |
| Standby Current | < 30 µA - allows permanent bus connection in sleep-mode ECUs without battery drain. |
| Bus Fault Protection | CANH/CANL short-circuit proof to GND, battery, and VCC - eliminates need for external protection diodes. |
| AEC-Q100 Grade | Grade 1 (−40 °C to +125 °C) - qualified for engine bay and chassis-mounted automotive applications. |
| ESD Robustness | ±8 kV HBM - meets ISO 10605 requirements for in-vehicle handling and assembly. |
Pinout & Package
Package: PG-DSO-8 (8-pin exposed pad SOIC variant, RoHS-compliant, moisture sensitivity level 3).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 TxD | Transmit Data Input | CMOS/TTL-compatible input with 20 kΩ internal pull-up; dominant state = LOW; triggers bus driver. |
| 2 GND | Ground Reference | Power and signal return path; must be low-inductance connection to minimize ground bounce. |
| 3 VCC | 5 V Supply Input | Primary power rail; requires 100 nF ceramic capacitor placed within 5 mm of pin for noise suppression. |
| 4 RxD | Receive Data Output | Digital output reflecting bus state (LOW = dominant); changes level during wake-up detection in standby mode. |
| 5 SPLIT | Split Termination Output | Drives midpoint of external 60 Ω split termination resistor pair to stabilize recessive common-mode voltage at VCC/2. |
| 6 CANL | Low-Side Bus Line | Differential bus terminal; internally short-circuit protected to GND, battery, and VCC. |
| 7 CANH | High-Side Bus Line | Differential bus terminal; features controlled slew rate to reduce electromagnetic emission (EME). |
| 8 STB | Standby Mode Control | Active-HIGH mode select with internal pull-up; LOW = normal mode, HIGH = standby with wake-up enabled. |
Key Features
| Feature | Design Value |
|---|---|
| Remote Wake-up via CAN Bus | Enables partial network wake-up without external wake-line wiring; reduces system-level harness complexity and ECU BOM cost. |
| Split Termination Support | Internal SPLIT pin drives external resistor divider to fix recessive common-mode voltage at VCC/2, improving noise immunity and bus stability. |
| TxD Time-out Function | Auto-disables driver after >150 µs dominant TxD assertion, preventing permanent bus dominance due to MCU lockup or firmware fault. |
| Overtemperature Shutdown | Deactivates CANH/CANL drivers above 160 °C junction temperature; re-enables only after TxD returns to recessive, avoiding bit corruption. |
| Automotive Transient Protection | Withstands ISO 7637-2 Pulse 1 (−150 V), Pulse 2a (+100 V), Pulse 3a/b (±200 V) without external clamping components. |
Applications
| Body Control Module (BCM) | Door Control Unit (DCU) |
|---|---|
Use Scenario: Centralized vehicle body electronics managing lighting, window lift, mirror adjustment, and door lock status via HS-CAN. IC Role / Device Role / Timing Role: Physical layer transceiver interfacing MCU CAN controller to 500 kbaud–1 Mbaud body network; provides wake-up on bus activity during sleep. Use Value: Enables zero-power standby with reliable wake-up response (<100 µs latency), reducing quiescent current to <30 µA per node. | Use Scenario: Distributed door electronics with local motor control, anti-pinch sensing, and LIN gateway functions. IC Role / Device Role / Timing Role: HS-CAN interface supporting diagnostic communication (UDS) and configuration updates while maintaining fail-safe bus termination behavior. Use Value: Split termination and bus-fault tolerance eliminate need for external bias resistors or protection ICs, shrinking PCB area by 12 mm². |
| Engine Control Unit (ECU) Subsystem | Chassis Domain Controller |
Use Scenario: Secondary CAN node in engine bay for sensor fusion (e.g., cam/crank sync, knock detection) with thermal resilience. IC Role / Device Role / Timing Role: High-immunity transceiver operating across −40 °C to +125 °C ambient; handles load-dump transients up to +100 V. Use Value: Integrated overtemperature shutdown prevents bus disruption during thermal overload, ensuring continued network availability for safety-critical diagnostics. | Use Scenario: Centralized chassis controller aggregating ABS, ESC, and ADAS sensor data over multi-drop HS-CAN backbone. IC Role / Device Role / Timing Role: Low-latency, EMI-hardened transceiver supporting deterministic 1 Mbaud messaging with <15 ns skew between CANH/CANL edges. Use Value: Controlled slew rate and symmetric edge timing reduce radiated emissions by 6 dBµV/m vs. legacy transceivers, easing EMC certification. |
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 TJA1042T/3 | Lower standby current (15 µA), integrated VIO supply for 3.3 V logic, no SPLIT pin | Lacks split termination support; requires external bias network for recessive stabilization | Select when system uses 3.3 V controllers and external termination is acceptable |
| ST TJA1057G | Higher ESD rating (±12 kV), wider common-mode (±70 V), no wake-up flag on RxD | Supports wake-up but does not assert RxD level change; requires external wake detection logic | Select when extreme ESD/EMI immunity is prioritized over integrated wake signaling |
Compared with TJA1042T/3 and TJA1057G, the TLE6251DSNTMA1 uniquely combines SPLIT-pin-based recessive stabilization, RxD-level wake-flag signaling, and AEC-Q100 Grade 1 qualification in a single PG-DSO-8 footprint-making it optimal for cost-sensitive, thermally demanding automotive nodes requiring autonomous wake-up and minimal external components.

FAQ
What is the function of the SPLIT pin?
The SPLIT pin outputs a reference voltage (VCC/2) to drive the center tap of an external 60 Ω split termination resistor network (two 30 Ω resistors). This stabilizes the recessive common-mode voltage on the CAN bus, improving noise immunity and ensuring reliable arbitration in electrically noisy automotive environments.
How does wake-up work in standby mode?
In standby mode (STB = HIGH), the driver and receiver are disabled, but the wake-up comparator remains active. When a dominant-to-recessive or recessive-to-dominant transition occurs on CANH/CANL, the internal logic toggles the RxD output level to signal wake-up-no external interrupt line required.
Is external termination required?
Yes-external 60 Ω total termination (e.g., 30 Ω–30 Ω split network tied to SPLIT pin) is mandatory for proper recessive level stabilization. The TLE6251DSNTMA1 does not integrate termination resistors; omitting them causes bus timing violations and arbitration failures.
Does the TLE6251DSNTMA1 support CAN FD?
No-it is specified only for classical high-speed CAN (ISO 11898-2) up to 1 Mbaud. It lacks the higher data phase timing flexibility and bit-rate switching required for CAN FD physical layer compliance.
