Product details
Overview
TLE9252VLCXUMA1 from Infineon Technologies is a high-speed CAN FD transceiver compliant with ISO 11898-2 (2016) and SAE J2284-4/-5, designed as the physical layer interface between microcontrollers and HS CAN buses in automotive systems. It supports data rates up to 5 MBit/s, features autonomous bus biasing, dual power supply (VBAT/VCC), and Sleep Mode current ≤25 µA. Used in radar modules and cluster ECUs where low EME and robust wake-up capability are critical.
For engineers reviewing the TLE9252VLCXUMA1 datasheet, TLE9252VLCXUMA1 pinout, TLE9252VLCXUMA1 application, or TLE9252VLCXUMA1 equivalent, key selection criteria include WUP filter time (0.5–1.8 µs), RxD recessive clamping, INH-controlled external circuitry, and fail-safe diagnostics via NERR output - all validated for AEC-Q100 automotive qualification.
Technical Context
The TLE9252VLCXUMA1 implements a fully differential transmitter/receiver pair with symmetrical loop delay (<10 ns) enabling reliable CAN FD frame transmission at 5 MBit/s. Its dual-supply architecture (VBAT for robustness during cranking, VCC for logic-level control) decouples battery transients from digital operation.
Wake-up functionality integrates both Bus Wake-up Pattern (WUP) detection with programmable filter window and Local Wake-up (LWU) via dedicated WAKE pin sensitive to rising/falling edges. Fail-safe logic includes TxD time-out, overtemperature shutdown, and undervoltage detection on VBAT, VCC, and VIO - each triggering defined state transitions and NERR assertion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Data Rate | 5 MBit/s - Enables full CAN FD payload throughput without signal integrity degradation. |
| Sleep Current | ≤25 µA - Ensures ultra-low quiescent power for always-on vehicle networks. |
| WUP Filter Time | 0.5 µs to 1.8 µs - Configurable window for OEM-specific wake-up pattern recognition. |
| ESD Robustness | ±10 kV HBM / ±9 kV IEC 61000-4-2 - Protects against assembly and in-vehicle electrostatic discharge events. |

Pinout & Package
Package: PG-TSON-14 (exposed thermal pad), RoHS-compliant, optimized for thermal performance in automotive under-hood environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 TxD | Transmit Data Input | CMOS input with internal pull-up to VIO; dominant state driven by logical low. |
| 2 GND | Ground Reference | Primary return path for VCC, VIO, VBAT, and CAN bus signals. |
| 3 VCC | Transmitter Supply | Provides regulated power to driver stage; requires 100 nF decoupling capacitor. |
| 4 RxD | Receive Data Output | CMOS output level-shifted to VIO; low during dominant bus state. |
| 5 VIO | Digital Interface Reference | Sets logic threshold for TxD/RxD/NSTB/EN; supports 3.3 V or 5 V MCUs. |
| 6 EN | Enable Control Input | Pull-down enabled; high = Normal-operating Mode, low = Stand-by/Sleep entry. |
| 7 INH | Inhibit Output | Open-drain output to disable external regulators or peripherals; high-Z in Sleep Mode. |
| 8 NERR | Error & Wake-Up Flag | Active-low open-drain output indicating fault conditions (overtemp, UVLO) or wake event. |
| 9 WAKE | Local Wake-Up Input | Edge-sensitive input terminated between GND and VBAT; triggers wake from Sleep/Stand-by. |
| 10 VBAT | Battery Supply Input | Direct connection to vehicle battery; powers internal LDOs and wake-up comparators. |
| 11 N.C. | No Connect | Internally unconnected pin; must remain floating or grounded per layout guidelines. |
| 12 CANL | CAN Bus Low Line | Differential bus terminal; integrated termination resistor not present - external 120 Ω required. |
| 13 CANH | CAN Bus High Line | Differential bus terminal; symmetric drive ensures <10 ns loop delay for FD timing compliance. |
| 14 NSTB | Stand-by Control Input | Pull-down enabled; high = Stand-by Mode (lower power than Normal, higher than Sleep). |
Key Features
| Feature | Design Value |
|---|---|
| Autonomous Bus Biasing | Meets ISO 11898-2 (2016) recessive voltage requirements without external resistors. |
| Dual Power Domain Architecture | VBAT powers wake-up logic and protection circuits independently of VCC, ensuring cranking resilience. |
| RxD Recessive Clamping | Prevents false dominant detection during bus idle; maintains valid logic levels under noise. |
| TxD Time-Out Protection | Forces recessive state after ~1.2 ms of continuous dominant TxD, preventing bus lockup. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed CAN FD transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP2562FD-H/SN | Single-supply (3.3 V only); no VBAT rail; lower ESD rating (±7 kV HBM). | Lacks autonomous bus biasing and cranking resilience; unsuitable for direct battery-connected nodes. | Preferred for cost-sensitive non-critical body electronics where VCC stability is guaranteed. |
| SN65HVD256DR | Legacy CAN 2.0B only (1 MBit/s max); no CAN FD support; no WUP/LWU features. | Cannot handle FD payloads or high-speed timing; lacks NERR diagnostics and INH control. | Only viable for legacy retrofit or non-FD subsystems with minimal diagnostic requirements. |
Compared with MCP2562FD-H/SN and SN65HVD256DR, the TLE9252VLCXUMA1 uniquely combines 5 MBit/s FD capability, dual-supply operation, AEC-Q100 qualification, and comprehensive fail-safe signaling - making it the only choice for new automotive domain controllers requiring functional safety-aware communication.

FAQ
What is the function of the INH pin on the TLE9252VLCXUMA1?
The INH (Inhibit) pin is an open-drain output used to control external circuitry such as voltage regulators or peripheral power switches. It becomes high-impedance in Sleep Mode, allowing downstream components to be powered down independently. During Normal or Stand-by Mode, INH is actively driven low to enable external supplies - providing coordinated power sequencing across the ECU.
How does the TLE9252VLCXUMA1 handle bus wake-up patterns?
The device detects standardized CAN bus wake-up patterns (WUP) using an internal comparator with configurable filter time (0.5–1.8 µs). This window rejects noise while recognizing OEM-defined dominant-recessive sequences. Upon detection, it asserts NERR and transitions from Sleep Mode to Stand-by or Normal Mode - all without MCU intervention.
Can the TLE9252VLCXUMA1 operate with a 3.3 V microcontroller?
Yes - the VIO pin accepts 3.3 V or 5 V reference voltage, automatically level-shifting TxD input thresholds and RxD output logic levels to match the MCU's I/O voltage. This eliminates external level translators and supports mixed-voltage system architectures common in modern automotive ECUs.
What failure conditions trigger the NERR output?
NERR goes low for overtemperature shutdown, undervoltage on VBAT/VCC/VIO, TxD time-out expiration, or RxD recessive clamping violation. It also pulses low during valid wake-up events (WUP or LWU). The pin serves dual purpose: fault flag and wake indicator - simplifying diagnostic firmware and reducing GPIO usage on the host MCU.
