Product details

Overview

TLE6251DSXUMA1 from Infineon Technologies is a high-speed CAN transceiver in PG-DSO-8 package, serving as the physical layer interface between CAN protocol controllers and differential bus lines per ISO/DIS 11898. It supports up to 1 Mbaud data rate, operates in 12 V/24 V automotive systems, features bus wake-up capability in standby mode, and includes TxD time-out, overtemperature protection, and split termination for recessive level stabilization.

For engineers reviewing the TLE6251DSXUMA1 datasheet, TLE6251DSXUMA1 pinout, TLE6251DSXUMA1 application, or TLE6251DSXUMA1 equivalent, key selection criteria include bus wake-up sensitivity, dominant-time timeout duration (t_TxD), common-mode voltage range (±36 V), short-circuit robustness (to battery, ground, V_CC), and AEC-Q100 qualification status for automotive deployment.

Technical Context

The TLE6251DSXUMA1 implements dual-mode operation-normal mode for active CAN communication and standby mode with ultra-low quiescent current (< 100 µA) while retaining bus-wake detection via RxD level change. Its Smart Power Technology SPT® integrates bipolar/CMOS control with DMOS power stages on a single die.

Wake-up logic responds to bus activity without external circuitry; the split termination pin stabilizes recessive common-mode voltage at V_CC/2, improving signal integrity. The driver stage incorporates slope control to reduce electromagnetic emission and features built-in overtemperature shutdown with automatic recovery only after a TxD dominant-to-recessive transition.

Key Specifications

Parameter	Value and Actual Design Meaning
Max Data Rate	1 Mbaud - enables real-time vehicle dynamics and powertrain control messaging
Bus Voltage Range	±36 V common-mode - ensures robust operation under automotive load-dump and jump-start conditions
Standby Current	< 100 µA - allows permanent bus connection in sleep-mode ECUs without battery drain
TxD Time-out	t_TxD = 1.5 ms typical - prevents bus lock-up during controller faults by auto-disabling driver output
Short-Circuit Protection	Protected to battery, ground, and V_CC - eliminates need for external fuse or current-limiting resistors
AEC-Q100 Grade	Grade 1 (−40 °C to +125 °C) - qualified for engine bay and transmission control unit mounting locations

Pinout & Package

Package: PG-DSO-8 (8-pin plastic dual small outline, exposed pad, RoHS-compliant).

Pin/Terminal	Circuit Role	Design Meaning
1 TxD	Transmit data input	20 kΩ internal pull-up; dominant state = LOW; drives CANH/CANL via internal driver stage
2 GND	Ground reference	Power and signal return path; must be low-inductance connection to minimize EMI
3 V_CC	5 V supply input	Requires local 100 nF ceramic decoupling to GND; powers internal logic and driver stages
4 RxD	Receive data output	LOW in dominant state; signals wake-up event in standby mode via level change
5 SPLIT	Split termination output	Drives 60 Ω split resistor network to stabilize recessive common-mode voltage at V_CC/2
6 CANL	Low-side bus line	Differential receiver input and driver output; short-circuit protected to battery, ground, V_CC
7 CANH	High-side bus line	Differential receiver input and driver output; symmetric slew control reduces EME
8 STB	Standby mode control	Internal pull-up; STB = HIGH → standby; STB = LOW → normal mode; no external pull required

Key Features

Feature	Design Value
Remote wake-up via CAN bus	Enables zero-power-node networks: detects bus activity while consuming < 100 µA, signaling wake via RxD toggle
Split termination support	Integrated SPLIT output drives external 60 Ω resistor pair to fix recessive common-mode at V_CC/2, improving noise immunity
TxD time-out function	Auto-disables driver after 1.5 ms dominant TxD, preventing bus lock-up during MCU hang or firmware fault
Overtemperature shutdown	Driver deactivation above safe junction temperature; re-enables only after TxD transitions recessive, avoiding bit errors
Automotive transient protection	Withstands ISO 7637-2 pulse 1, 2a, 3a/b and IEC 61000-4-4 EFT without external clamping components

Applications

Use Scenario: Closed-loop motor control feedback and torque assist coordination between EPS ECU and steering column actuator.

IC Role / Device Role / Timing Role: Fault-tolerant CAN interface with TxD time-out and overtemperature recovery to prevent loss of steering assist.

Use Value: Driver auto-recovery after thermal shutdown avoids dangerous limp-home mode interruption during sustained steering load.

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 (30 µA), integrated VIO supply for 3.3 V controllers, no split termination pin	Lacks SPLIT pin; requires external bias network for recessive stabilization	Select when interfacing with 3.3 V MCUs and lowest possible quiescent current is critical
ST TLE6251-2G	Same pinout and function but with enhanced ESD rating (±8 kV HBM), identical SPLIT and wake-up behavior	Drop-in replacement with improved robustness; same PCB layout and firmware	Select when higher ESD immunity is required without design change

Compared with TJA1042T/3 and TLE6251-2G, the TLE6251DSXUMA1 uniquely combines split termination drive, AEC-Q100 Grade 1 qualification, and proven passive bus behavior in mixed-power networks-making it optimal for legacy automotive platforms requiring field-proven reliability and minimal BOM changes.

FAQ

What is the purpose of the SPLIT pin on the TLE6251DSXUMA1?

The SPLIT pin provides a dedicated output to drive an external 60 Ω split termination resistor network between CANH and CANL. This actively stabilizes the recessive common-mode voltage at V_CC/2, improving signal symmetry, reducing electromagnetic emissions, and enhancing noise immunity-especially critical in long or branched automotive CAN networks.

How does the TLE6251DSXUMA1 handle bus wake-up in standby mode?

In standby mode, the receiver and driver are disabled, but the wake-up logic remains active. When bus activity occurs, the differential input detects the dominant/recessive transitions and toggles the RxD output level accordingly-providing a hardware wake flag to the microcontroller without requiring continuous power to the full transceiver.

Is the TLE6251DSXUMA1 compatible with 3.3 V microcontrollers?

Yes-the TxD and STB inputs are compatible with both 3.3 V and 5 V logic levels due to their TTL/CMOS input thresholds and internal pull-ups. The RxD output is also 5 V tolerant and can interface directly with 3.3 V MCU inputs when used with appropriate level-shifting or series resistance per system requirements.

Does the TLE6251DSXUMA1 require external protection components for ISO 7637-2 compliance?

No-its integrated protection architecture withstands ISO 7637-2 Pulse 1 (inductive load dump), Pulse 2a (battery disconnect), and Pulses 3a/3b (switching transients) without external TVS diodes or RC networks, simplifying PCB layout and reducing BOM cost while maintaining AEC-Q100 conformance.
