Product details
Overview
TLE62543GXUMA2 from Infineon Technologies is a fault-tolerant low-speed CAN transceiver in PG-DSO-14 package, supporting up to 125 kBaud data rate, integrated bus failure management for single-wire fallback, and dual-edge wake-up capability. It interfaces CAN protocol controllers with physical bus lines in automotive body electronics and industrial control networks where robustness against wiring faults is critical.
For engineers reviewing the TLE62543GXUMA2 datasheet, TLE62543GXUMA2 pinout, TLE62543GXUMA2 application, or TLE62543GXUMA2 equivalent, key selection criteria include bus fault recovery behavior, sleep-mode current draw (≤10 µA), wake-up sensitivity, termination resistor control (RRTL/RTH), and AEC-Q100 qualification for automotive deployment.
Technical Context
The TLE62543GXUMA2 implements a dual-mode physical layer: differential signaling under normal operation (CANH/CANL) and automatic fallback to single-wire mode upon detection of open/short bus faults. Its internal failure management actively controls RTH and RTL outputs to reconfigure termination during line failures.
It supports three operational states-Normal, Stand-by, and Sleep-controlled via NSTB and ENT pins, with wake-up triggered by either CAN bus activity or external WK pin edge transitions. Thermal protection and battery fail flag (VBAT monitoring) are embedded for automotive safety-critical use.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | Up to 125 kBaud - enables reliable communication in low-speed automotive sub-networks (e.g., lighting, door modules). |
| Supply Voltage (VS) | 9 V to 16 V - directly compatible with automotive battery rail without external regulation. |
| Sleep Current | ≤10 µA - minimizes parasitic drain in always-on vehicle systems during ignition-off periods. |
| Bus Fault Recovery | Automatic single-wire mode activation on CANH/CANL open or short - maintains node-level communication integrity during wiring degradation. |
| Wake-Up Sensitivity | Dual-edge on WK pin + bus-level wake-up - ensures responsive exit from low-power states without dedicated polling. |
| Termination Control | RTH/RTL outputs drive external 500 Ω–16 kΩ resistors - enables dynamic bus topology adaptation during failure events. |
| AEC-Q100 Grade | Grade 1 (−40 °C to +125 °C ambient) - qualified for engine bay and chassis-mounted applications. |
Pinout & Package
Package: PG-DSO-14 (14-pin exposed pad SOIC variant, RoHS-compliant, moisture-sensitive level 3).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 INH | Inhibit output | Controls external voltage regulator enable; HIGH in sleep mode to shut down auxiliary supplies. |
| 2 TxD | Transmit data input | Controller-side digital input; LOW asserts dominant bus state, HIGH enables recessive state. |
| 3 RxD | Receive data output | Controller-side digital output; reflects bus state (LOW = dominant, HIGH = recessive). |
| 4 NERR | Error flag output | Active-low indicator of bus error conditions; used for diagnostic logging or controller fault response. |
| 5 NSTB | Not stand-by input | Digital mode select: HIGH enables Normal/Stand-by; LOW forces Sleep or RxD-only mode. |
| 6 ENT | Enable transfer input | Digital mode select: HIGH enables transmitter; LOW disables driver stage while preserving receiver. |
| 7 WK | Wake-up input | Dual-edge sensitive trigger; initiates wake-up sequence from Sleep/Stand-by without bus traffic. |
| 8 RTH | Termination resistor output (H) | Drives external resistor to CANH; controlled by internal failure logic during bus fault recovery. |
| 9 RTL | Termination resistor output (L) | Drives external resistor to CANL; coordinated with RTH for adaptive bus termination. |
| 10 VCC | Logic supply input | +5 V supply for internal logic; requires local ceramic decoupling to GND. |
| 11 CANH | CAN high bus line | Physical bus connection; dominant state driven LOW relative to CANL during transmission. |
| 12 CANL | CAN low bus line | Physical bus connection; dominant state driven HIGH relative to CANH during transmission. |
| 13 GND | Ground reference | Common return path for logic and bus circuitry; must be low-impedance connection. |
| 14 VS | Battery supply input | Main power input (9–16 V); powers bus drivers and internal regulators; requires local ceramic decoupling. |
Key Features
| Feature | Design Value |
|---|---|
| Fault-tolerant single-wire mode | Automatically engages when CANH or CANL is open/shorted, maintaining communication over remaining functional line. |
| Integrated bus failure management | Monitors bus voltage asymmetry and line continuity; triggers RTH/RTL control and mode transitions without host intervention. |
| Low-power sleep mode | Consumes ≤10 µA while retaining wake-up capability via WK pin or bus activity - suitable for always-on vehicle nodes. |
| Thermal shutdown protection | Disables bus drivers at junction temperature >165 °C; recovers automatically after cooldown - prevents thermal runaway in enclosed environments. |
| Battery fail detection | VBAT monitoring circuit asserts fail flag below 6.5 V - enables early warning of weak battery before system reset. |
Applications
| Body Control Module (BCM) | Door Module Network |
|---|---|
Use Scenario: Centralized control of lighting, windows, locks, and mirrors across multiple doors using distributed CAN nodes. IC Role / Device Role / Timing Role: Physical layer interface between microcontroller and low-speed CAN bus; provides fault resilience during harness chafing or connector corrosion.

Use Value: Triggers graceful shutdown and position save before power loss - avoids incomplete seat moves that could trap occupant. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar low-speed fault-tolerant CAN transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN65HVD230DR | No built-in bus failure management; no single-wire fallback; no RTH/RTL control outputs. | Limited to standard differential CAN networks without wiring fault resilience requirements. | Select only if full bus redundancy is unnecessary and cost is primary constraint. |
| TJA1055T/3 | Supports single-wire mode but lacks dual-edge WK input and integrated battery fail flag. | Suitable for basic body electronics where wake-up timing tolerance is relaxed and BMS integration is not required. | Prefer when legacy design compatibility with NXP footprint is needed and VBAT monitoring is handled externally. |
Compared with SN65HVD230DR and TJA1055T/3, the TLE62543GXUMA2 uniquely combines automatic bus-failure-triggered single-wire operation, dual-edge wake-up, and battery fail detection - making it the only choice for AEC-Q100-compliant systems requiring uninterrupted communication under wiring degradation.

FAQ
What is the maximum allowable ground offset voltage in single-wire mode?
The TLE62543GXUMA2 supports one-wire transmission with ground offset voltages up to 1.5 V, as specified in the datasheet Rev. 2.1. This allows operation across non-isolated domains where common-mode voltage differences exist between nodes, such as between chassis-grounded and battery-grounded ECUs.
Does the device require external termination resistors?
Yes - external termination resistors (500 Ω to 16 kΩ) must be connected between RTH and CANH, and between RTL and CANL. The TLE62543GXUMA2 does not integrate termination; instead, its RTH/RTL outputs actively control these external resistors during bus failure events.
How does the device prevent bus occupation during CAN controller failure?
If TxD is held permanently dominant, the TLE62543GXUMA2 disables both CANH and CANL drivers after a timeout period. This prevents a faulty controller from blocking the bus, ensuring other nodes retain communication capability - a critical safety feature in distributed automotive networks.
Is the TLE62543GXUMA2 pin-compatible with earlier TLE6254 variants?
Yes - TLE62543GXUMA2 is functionally and mechanically identical to TLE6254-3G in PG-DSO-14 package, including identical pinout, electrical characteristics, and failure management behavior. The 'XUMA2' suffix denotes tape-and-reel packaging per Infineon's ordering convention.
