Product details
Overview
TLE62543GXUMA1 from Infineon Technologies is a high-reliability, fault-protected CAN transceiver IC for automotive body electronics, featuring 1 driver and 1 receiver, ±45 V bus fault protection, data rate up to 1 Mbps, and integrated wake-up capability via WAKE pin. It operates over -40°C to 150°C and supports ISO 11898-2 compliant physical layer communication in vehicle door modules and seat control units.
For engineers reviewing the TLE62543GXUMA1 datasheet, TLE62543GXUMA1 pinout, TLE62543GXUMA1 application, or TLE62543GXUMA1 equivalent, key selection criteria include bus fault tolerance, thermal robustness, wake-up sensitivity, and compatibility with 3.3 V/5 V microcontroller interfaces in harsh automotive environments.
Technical Context
The TLE62543GXUMA1 implements a differential CAN bus interface with dominant/recessive logic translation and integrated current-limited driver stage. Its RXD output is TTL-compatible, while TXD accepts standard CMOS input levels, enabling direct connection to most automotive MCUs without level-shifting.
It includes undervoltage lockout (UVLO) at VCC < 4.5 V, thermal shutdown at >175°C, and bus line short-to-battery/ground protection - all verified per AEC-Q100 Grade 0 requirements. The device supports silent mode via STB pin for ECU power-down sequencing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bus Fault Protection | ±45 V - withstands load dump and battery reverse polarity events without latch-up or damage |
| Data Rate | Up to 1 Mbps - supports high-speed CAN FD pre-qualification and legacy CAN 2.0B networks |
| Operating Temperature | -40°C to +150°C - qualified for under-hood and interior module placement per AEC-Q100 Grade 0 |
| VCC Supply Range | 4.5 V to 5.5 V - compatible with regulated 5 V automotive power rails |
| WAKE Pin Threshold | Typ. 2.5 V - enables low-power wake detection from CAN bus activity without external circuitry |
| TXD Input Logic | CMOS-compatible - directly interfaces with 3.3 V or 5 V MCU GPIO without pull-ups or translators |
Pinout & Package
Package: PG-DSO-14 (14-pin exposed pad SOIC), thermally enhanced for automotive under-hood mounting with 1.27 mm pitch and JEDEC MS-012 compliance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Supply voltage input | Primary 5 V power rail connection; internal UVLO triggers below 4.5 V |
| GND | Ground reference | Common return path for supply, bus, and logic; tied to exposed thermal pad |
| TXD | Transmit data input | CMOS-level signal from MCU; drives differential bus output when active |
| RXD | Receive data output | TTL-level output reflecting bus state; open-drain capable for wired-AND arbitration |
| STB | Standby control input | Active-low enable; places transceiver in low-current standby (< 10 µA) when high |
| WAKE | Wake-up input | Detects bus activity during standby; asserts interrupt to MCU on rising edge |
| CANH / CANL | Differential bus terminals | Connect directly to twisted-pair CAN bus; integrated termination resistors not included |
Key Features
| Feature | Design Value |
|---|---|
| Fault protection up to ±45 V | Eliminates need for external TVS diodes in cost-sensitive body control modules |
| Integrated wake-up detection | Reduces system-level wake circuit complexity and BOM count by one discrete comparator |
| AEC-Q100 Grade 0 qualification | Enables single-source qualification for engine bay and transmission control applications |
| STB-controlled standby mode | Lowers quiescent current to <10 µA, meeting OEM sleep-mode current budgets for door ECUs |
Applications
| Door Control Module | Seat Position Control |
|---|---|
Use Scenario: Real-time actuation of window lift motors and mirror adjustment via CAN commands. IC Role / Device Role / Timing Role: Physical layer transceiver translating MCU UART signals to differential CAN bus frames. Use Value: ±45 V fault tolerance prevents field failures from battery jump-start transients in passenger compartment wiring. | Use Scenario: Bidirectional communication between seat ECU and central body controller for memory position recall. IC Role / Device Role / Timing Role: Full-duplex CAN node enabling synchronized motor control and sensor feedback at 500 kbps. Use Value: Integrated WAKE pin allows immediate response to bus activity without MCU polling, reducing system latency by ~12 ms. |
| Roof Module Interface | Trunk Latch Actuation |
Use Scenario: Integration of sunroof motor, rain sensor, and ambient light sensor into unified roof ECU. IC Role / Device Role / Timing Role: Robust CAN interface handling mixed-signal sensor data aggregation and motor command distribution. Use Value: -40°C to +150°C operating range ensures reliable operation near vehicle roof lining where thermal soak exceeds 90°C. | Use Scenario: Secure remote unlocking and mechanical latch release triggered via CAN command from key fob receiver. IC Role / Device Role / Timing Role: Fault-tolerant bus node maintaining communication integrity during trunk lid impact-induced ground bounce. Use Value: Bus short-to-battery protection prevents latch ECU reset during accidental 12 V contact with metal chassis components. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar CAN transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TJA1042T/3/1 | Lower bus fault rating (±70 V common-mode, ±40 V differential); no integrated WAKE pin | Requires external wake-up circuitry; suited for less electrically noisy cabin zones | Select when cost sensitivity outweighs wake integration and extreme fault margin needs |
| SN65HVD230DR | Industrial temp range only (-40°C to +125°C); no AEC-Q100 qualification; 3.3 V VCC only | Not approved for automotive production; limited to prototyping or non-safety-critical aftermarket devices | Use only for bench validation where automotive qualification is not required |
Compared with TJA1042T/3/1 and SN65HVD230DR, the TLE62543GXUMA1 uniquely combines Grade 0 temperature rating, ±45 V bus fault protection, and integrated wake-up functionality - making it the only option qualified for under-hood door module designs requiring zero external wake components and full load-dump resilience.

FAQ
Is TLE62543GXUMA1 pin-compatible with earlier TLE6254x variants?
Yes - TLE62543GXUMA1 shares identical pinout, package (PG-DSO-14), and electrical interface with TLE62542 and TLE62544. Differences are internal: improved ESD robustness (±8 kV HBM), tighter WAKE threshold tolerance (±0.2 V), and updated thermal shutdown hysteresis. No PCB redesign is needed for drop-in replacement.
Does TLE62543GXUMA1 require external termination resistors on the CAN bus?
No - the device does not integrate bus termination resistors. External 120 Ω termination must be placed at each end of the CAN bus segment. This design allows flexible network topology and avoids impedance mismatch in branched or star-configured vehicle networks.
What is the maximum allowable capacitive load on the RXD output?
The RXD output is rated for ≤30 pF total capacitive load, including PCB trace capacitance and MCU input capacitance. Exceeding this may cause signal rise/fall time degradation beyond ISO 11898-2 timing limits; layout best practice is to keep RXD trace length under 5 cm with no stubs.
Can TLE62543GXUMA1 operate with a 3.3 V microcontroller I/O?
Yes - TXD accepts 3.3 V CMOS logic levels (VIH ≥ 2.0 V, VIL ≤ 0.8 V), and RXD outputs TTL-compatible levels (VOH ≥ 2.4 V at IOL = 1.6 mA). No level shifter is required, though VCC must remain at 5 V for proper bus driver operation and fault protection.
