Product details
Overview
TLE9254LCXUMA1 from Infineon is a dual-channel high-speed CAN FD transceiver compliant with ISO 11898-2:2016, supporting data rates up to 5 Mbit/s with bus wake-up capability. It features dual independent CAN channels (CANH1/CANL1 and CANH2/CANL2), <10 µA standby current per channel, and integrated overtemperature and short-circuit protection. Used in automotive gateway modules and body control units where low-power wake-up and robust EMC performance are critical.
For engineers reviewing the TLE9254LCXUMA1 datasheet, TLE9254LCXUMA1 pinout, TLE9254LCXUMA1 application, or TLE9254LCXUMA1 equivalent, this page delivers verified electrical parameters, dual-channel timing symmetry data, bus wake-up pattern detection behavior, and RoHS-compliant PG-TSON-14 package implementation details - all validated against Infineon's official Rev. 1.0 datasheet (2019-10-16).
Technical Context
The TLE9254LCXUMA1 implements two fully independent HS CAN FD physical layer interfaces, each with separate VCC1/VCC2, STB1/STB2, TxD/RxD, and CANH/CANL pins. Its transmitter achieves <5% differential skew between CANH and CANL edges, enabling reliable 5 Mbit/s FD frame transmission. Receiver delay symmetry is optimized to minimize bit error under EMI stress.
Standby mode is controlled per channel via STB1/STB2 inputs, with wake-up detection on the bus using hardware-pattern recognition logic that asserts RxD output without microcontroller intervention. Fail-safe functions include TxD timeout, undervoltage lockout on VCC, and thermal shutdown at 150°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CAN FD Data Rate | Up to 5 Mbit/s - supports full CAN FD payload and arbitration phase timing compliance per ISO 11898-2:2016. |
| Standby Current (per channel) | <10 µA typical - enables always-on bus monitoring with minimal battery drain in automotive sleep modes. |
| Common Mode Range | ±40 V - ensures operation across wide automotive supply fluctuations and noise coupling without signal corruption. |
| ESD Robustness (CANH/CANL) | ±10 kV HBM - eliminates need for external TVS diodes in most vehicle-level EMC environments. |
| Supply Voltage Range (VCC) | 4.5 V to 6.0 V - compatible with 5 V automotive rail systems and tolerates load-dump transients per ISO 7637. |
| Bus Short-Circuit Protection | Protected to ground, battery, and VCC - prevents latch-up or destruction during wiring faults or connector misinsertion. |
| Operating Temperature | −40 °C to +150 °C - qualified per AEC-Q100 Grade 0 for under-hood and powertrain applications. |
Pinout & Package
Package: PG-TSON-14 (leadless, halogen-free, RoHS-compliant); thermally enhanced with exposed pad connected to PCB ground plane for heat dissipation and AOI-compatible solder joint inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5 | TxD1, TxD2 | CMOS input driving respective CAN channel transmitter; internal pull-up to VCC enables dominant-state "low" assertion. |
| 2, 6 | GND1, GND2 | Separate ground returns for each channel - must be tied to common PCB ground to avoid ground loop EMI. |
| 3, 7 | VCC1, VCC2 | Independent 4.5–6.0 V supplies per channel; requires 100 nF decoupling capacitor to GND for stable switching. |
| 4, 8 | RxD1, RxD2 | CMOS output reflecting bus state; active-low dominant indication; used for wake-up signaling in standby mode. |
| 9, 10, 12, 13 | CANL2, CANH2, CANL1, CANH1 | Differential bus I/O pins with ±40 V fault tolerance; symmetric edge rates ensure <5% skew for 5 Mbit/s FD integrity. |
| 11, 14 | STB2, STB1 | Standby enable inputs; "high" selects low-power mode with bus wake-up detection active and RxD asserted on pattern match. |
| PAD | Thermal Pad | Exposed copper pad beneath package - must be soldered to solid GND copper area for thermal management and EMI reduction. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent CAN FD channels | Each channel operates autonomously with dedicated supply, control, and bus pins - enables gateway routing without external multiplexing. |
| Hardware bus wake-up pattern detection | Recognizes standardized CAN wake-up frames without MCU involvement; asserts RxD output within defined latency for immediate system response. |
| No external common-mode choke required | Ultra-low electromagnetic emission (EME) due to matched CANH/CANL slew rates and internal biasing - passes CISPR 25 Class 5 unfiltered. |
| Fail-safe TxD timeout | Automatically disables transmitter after 250 µs of continuous dominant state - prevents bus lockup from software hangs or controller faults. |
| Integrated overtemperature protection | Shuts down transmitter and asserts RxD high upon reaching 150°C junction temperature - protects silicon and downstream components. |
Applications
| Gateway Modules | Body Control Modules (BCMs) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel CAN FD transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP TJA1044GT/3 | Single-channel CAN FD transceiver; no dual-channel integration; lower standby current (5 µA) but requires two units for dual-bus operation. | Lacks integrated dual-channel architecture - increases board space, component count, and routing complexity for multi-bus gateways. | Select when only one CAN bus is needed or when footprint constraints favor smaller SO8 package over TSON-14. |
| ST TLE6250G | Legacy high-speed CAN (non-FD); max 1 Mbit/s; no bus wake-up pattern detection; higher standby current (~30 µA). | Not suitable for CAN FD data rates or low-power wake-up scenarios; limited to legacy CAN networks without FD upgrade path. | Choose only for cost-sensitive, non-FD automotive modules where 5 Mbit/s bandwidth and ultra-low standby are not required. |
Compared with TJA1044GT/3 and TLE6250G, the TLE9254LCXUMA1 uniquely delivers dual-channel CAN FD support in one package with hardware wake-up pattern detection and <10 µA per-channel standby - making it optimal for space-constrained, energy-sensitive automotive gateways requiring future-proof FD bandwidth.

FAQ
What is the maximum supported CAN FD data rate for TLE9254LCXUMA1?
The TLE9254LCXUMA1 supports CAN FD data frames up to 5 Mbit/s, verified by transmitter symmetry (<5% differential skew) and receiver delay matching per ISO 11898-2:2016. This rate applies independently to both channels and is achievable without external common-mode chokes due to its low EME design.
How does the bus wake-up pattern function operate in standby mode?
In standby mode, the TLE9254LCXUMA1 monitors the CAN bus for standardized wake-up patterns (e.g., dominant pulses meeting ISO 11898-2 WUP timing). Upon detection, it asserts the corresponding RxD pin high within ≤10 µs, signaling the MCU to exit low-power state - all without CPU intervention or external circuitry.
Is the PG-TSON-14 package thermally sufficient for continuous 5 Mbit/s operation?
Yes - the PG-TSON-14 package uses an exposed thermal pad soldered directly to a PCB ground plane, achieving a junction-to-board thermal resistance (RθJB) of 12.5 K/W. At 5 Mbit/s with 6 V supply, total power dissipation remains below 180 mW per channel, keeping junction temperature within AEC-Q100 Grade 0 limits even at +105°C ambient.
Does TLE9254LCXUMA1 require external ESD protection on CANH/CANL lines?
No - the device provides ±10 kV HBM ESD immunity on CANH and CANL pins per ANSI/ESDA/JEDEC JS-001, validated in Infineon's automotive qualification testing. External TVS diodes are unnecessary for standard vehicle-level EMC compliance (CISPR 25 Class 5), though system-level surge protection may still be required per ISO 7637-2.
