Product details
Overview
TLE7250GXUMA2 from Infineon Technologies is a high-speed CAN transceiver compliant with ISO 11898-2, serving as the physical layer interface between CAN protocol controllers and differential bus lines. It supports data rates up to 1 Mbps, operates over a supply range of 4.5 V to 5.5 V, features integrated overtemperature and undervoltage protection, and delivers <1 µA bus leakage current in power-down state-enabling robust communication in automotive body control modules.
For engineers reviewing the TLE7250GXUMA2 datasheet, TLE7250GXUMA2 pinout, TLE7250GXUMA2 application, or TLE7250GXUMA2 equivalent, key selection considerations include its AEC-Q100 qualification, PG-DSO-8 package compatibility with TLE6250G, fail-safe TxD time-out function, and passive bus behavior in mixed-supply CAN networks.
Technical Context
The TLE7250GXUMA2 implements a fully differential HS-CAN physical layer with matched CANH/CANL slew-rate control to minimize electromagnetic emission (EME) across 1–100 MHz. Its receiver uses a precision comparator with hysteresis referenced to VCC/2 for reliable dominant/recessive detection at VDIFF ≥ 1.5 V (dominant) and ≤ 0.5 V (recessive).
Mode control is managed via two logic inputs: NEN (Not Enable) and NRM (Not Receive-only Mode), enabling three operational states-normal (transmit + receive), receive-only, and stand-by-with automatic default-to-stand-by on power-up due to internal pull-ups. The device remains electrically passive on CANH/CANL during power-down, preventing bus contention in partially-supplied networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bus Data Rate | Up to 1 Mbps - enables real-time diagnostics and ECU coordination in modern vehicle architectures. |
| Supply Voltage Range | 4.5 V to 5.5 V - accommodates automotive battery fluctuations without external regulation. |
| Dominant Differential Voltage | VDIFF ≥ 1.5 V - ensures noise-immune signal recognition per ISO 11898-2 specification. |
| Power-down Bus Leakage | <1 µA - prevents unintended bus loading when nodes are unpowered in mixed-supply networks. |
| ESD Immunity | ±8 kV HBM - protects against handling and system-level electrostatic discharge per IEC61000-4-2. |
| Operating Temperature | −40 °C to +150 °C - meets AEC-Q100 Grade 0 requirements for under-hood applications. |
| Common-Mode Range | −27 V to +40 V - sustains operation during load-dump and reverse-battery transients. |
Pinout & Package
Package: PG-DSO-8 (RoHS-compliant, surface-mount, 8-pin plastic dual small-outline). Pin assignment matches TLE6250G footprint for drop-in replacement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 TxD | Transmit Data Input | CMOS-compatible input with internal pull-up to VCC; "low" asserts dominant bus state. |
| 2 GND | Ground Reference | Primary return path for VCC and bus drivers; requires low-inductance PCB layout. |
| 3 VCC | Supply Voltage | 4.5–5.5 V rail; mandates 100 nF ceramic decoupling capacitor placed adjacent to pin. |
| 4 RxD | Receive Data Output | CMOS output reflecting bus state; "low" indicates dominant, "high" recessive. |
| 5 NRM | Receive-only Mode Control | Active-low input; "low" disables transmitter while preserving receiver functionality. |
| 6 CANL | CAN Bus Low | Differential bus terminal; sinks current during dominant state; high-impedance in power-down. |
| 7 CANH | CAN Bus High | Differential bus terminal; sources current during dominant state; high-impedance in power-down. |
| 8 NEN | Enable Control | Active-low input; "low" activates normal or receive-only mode; "high" forces stand-by. |
Key Features
| Feature | Design Value |
|---|---|
| ISO 11898-2 Compliance | Fully compliant physical layer implementation-including differential voltage thresholds, timing, and fault tolerance-verified per standard test conditions. |
| Fail-Safe TxD Time-out | Automatically disables transmitter after ~1.5 ms of continuous dominant TxD, preventing bus lock-up during controller faults. |
| Passive Bus Behavior | In power-down, CANH/CANL present >1 MΩ impedance-eliminates bus contention in networks with mixed power states. |
| EMI-Optimized Slew Rate | Controlled edge rates on CANH/CANL reduce radiated emissions without compromising 1 Mbps timing margins. |
| AEC-Q100 Qualified | Qualified to Grade 0 (−40 °C to +150 °C ambient), including HTOL, TC, and ESD stress testing per automotive reliability standards. |

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 |
|---|---|---|---|
| SN65HVD230DR | Lower operating temperature range (−40 °C to +125 °C); no integrated TxD time-out or undervoltage detection. | Lacks AEC-Q100 qualification and failsafe features required for automotive safety-critical nodes. | Preferred for cost-sensitive industrial CAN networks where extended temperature and automotive robustness are not required. |
| TJA1042T/3/1 | Includes wake-up capability and improved ESD (±12 kV); identical ISO 11898-2 compliance and PG-DSO-8 footprint. | Supports local wake-up via bus activity-enabling ultra-low-power sleep modes not available in TLE7250GXUMA2. | Recommended when system-level wake-up functionality is needed; otherwise, TLE7250GXUMA2 offers superior passive bus behavior in power-down. |
Compared with SN65HVD230DR and TJA1042T/3/1, the TLE7250GXUMA2 provides the lowest bus leakage in power-down (<1 µA vs. ~5 µA) and optimized symmetry for EME reduction-making it ideal for large, mixed-supply automotive CAN clusters where bus integrity during partial node sleep is critical.

FAQ
Is TLE7250GXUMA2 pin-compatible with TLE6250G?
Yes. Although pin 5 (RM → NRM) and pin 8 (INH → NEN) have updated names, their functions and electrical behavior are identical. The PG-DSO-8 footprint, pin numbering, and signal routing match exactly-enabling direct replacement without PCB redesign.
What happens to CANH/CANL in power-down state?
In power-down (NEN = high), both CANH and CANL enter high-impedance state with leakage current <1 µA. This prevents bus loading or short-circuit risk when other nodes remain active-critical for partial-network wake-up strategies in modern vehicle architectures.
Does TLE7250GXUMA2 support CAN FD?
No. The TLE7250GXUMA2 is designed exclusively for classical High-Speed CAN (ISO 11898-2) up to 1 Mbps. It lacks the enhanced bit-timing flexibility and arbitration-phase handling required for CAN FD frames.
How does the TxD time-out function improve system reliability?
The internal timer disables the transmitter after ~1.5 ms of continuous dominant TxD output. This prevents bus lock-up if the connected CAN controller freezes or outputs a stuck-low signal-ensuring network recovery without manual reset or node isolation.
