Product details
Overview
TLE62512GXUMA3 from Infineon is a high-speed CAN transceiver compliant with ISO 11898-5, supporting data rates up to 1 MBaud, featuring bus wake-up and local wake-up capability, integrated failure diagnosis via NERR output, and split termination for recessive level stabilization. It operates in mixed-power-supply automotive HS-CAN networks with VIO and VS supply separation.
For engineers reviewing the TLE62512GXUMA3 datasheet, TLE62512GXUMA3 pinout, TLE62512GXUMA3 application, or TLE62512GXUMA3 equivalent, key selection criteria include wake-up source recognition, TxD time-out and short-circuit diagnostics, ±9 kV ESD robustness, and RoHS-compliant PG-DSO-14 packaging for AEC-Q100-qualified automotive use.
Technical Context
The TLE62512GXUMA3 implements a fully differential HS-CAN physical layer interface with separate VIO (1.8–5.5 V) and VS (5–27 V) supplies, enabling interoperability with diverse microcontrollers while maintaining bus fault resilience. Its low-quiescent-current sleep mode (<15 µA) and passive bus behavior during power-down support energy-sensitive automotive body electronics.
Integrated diagnostics include TxD-to-RxD short detection, CANH/CANL short recognition, dominant clamping, under-voltage monitoring at VCC/VIO/VS, and over-temperature protection - all signaled via open-drain NERR and RxD outputs. Wake-up is triggered by bus activity (remote) or WK pin edge transitions (local), with mode control via EN/NSTB pins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | Up to 1 MBaud - supports full-speed CAN FD preambles and legacy CAN 2.0B real-time control messaging. |
| ESD Robustness | ±9 kV HBM per IEC 61000-4-2 - eliminates need for external TVS diodes in most automotive cabin modules. |
| Sleep Current | ≤15 µA at TA = 25°C - enables always-on network nodes without battery drain in parked vehicle scenarios. |
| VIO Range | 1.8 V to 5.5 V - matches logic levels of 1.8 V, 3.3 V, and 5 V microcontrollers without level-shifting circuitry. |
| VS Operating Range | 5 V to 27 V - covers cold-crank (5.5 V) to load-dump (27 V) conditions in 12 V automotive systems. |
| Fail-Safe Diagnostics | NERR active-low flag reports TxD timeout, RxD recessive clamp, CANH/CANL shorts, and under-voltage events - enables deterministic node-level fault isolation. |
| Package | PG-DSO-14 (RoHS-compliant, AEC-Q100 qualified) - surface-mount footprint compatible with automated SMT assembly and thermal cycling reliability. |
Pinout & Package
Package: PG-DSO-14 (14-pin exposed-pad SOIC variant with enhanced thermal performance and automotive-grade molding compound).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 TxD | Transmit Data Input | CMOS input with internal pull-up to VIO; "low" asserts dominant bus state; tolerant of 5 V logic when VIO = 3.3 V. |
| 2 GND | Ground Reference | Dedicated analog ground pin; must be connected to low-impedance PCB ground plane to minimize EMI coupling into receiver path. |
| 3 VCC | Transceiver Core Supply | Supplies internal driver/receiver circuitry; requires 100 nF ceramic decoupling capacitor placed ≤3 mm from pin. |
| 4 RxD | Receive Data Output | CMOS output referenced to VIO; "low" = dominant, "high" = recessive; used for failure indication in diagnostic modes. |
| 5 VIO | Logic Interface Supply | Defines logic thresholds for TxD, RxD, EN, NSTB, NERR; decoupled with 100 nF capacitor to suppress MCU switching noise. |
| 6 EN | Enable Control Input | Pull-down enabled; driven high to enter Normal Mode; low or floating places device in Standby/Sleep depending on NSTB state. |
| 7 INH | Inhibit Output | Open-drain output controlling external regulators or power switches; high-impedance in Sleep mode to avoid loading. |
| 8 NERR | Error Flag Output | Active-low open-drain flag indicating wake-up event or any failure condition (TxD timeout, shorts, UV, over-temp). |
| 9 WK | Local Wake-Up Input | Edge-sensitive (rising/falling); enables wake from Sleep without bus traffic - used for door handle or sensor-initiated wake. |
| 10 VS | Battery Supply Input | Direct connection to vehicle battery; withstands load dump transients up to ISO 7637-2 Pulse 5a (60 V/100 ms). |
| 11 SPLIT | Split Termination Output | Drives external 60 Ω split termination resistor midpoint to stabilize recessive common-mode voltage at 2.5 V. |
| 12 CANL | CAN Bus Low Line | Differential bus terminal; internally protected against ±40 V faults; connects directly to twisted-pair CAN-L wire. |
| 13 CANH | CAN Bus High Line | Differential bus terminal; symmetric drive strength to CANL ensures <±100 mV common-mode error during dominant states. |
| 14 NSTB | Standby Control Input | Pull-down enabled; high + EN high = Normal Mode; high + EN low = Standby Mode (reduced current, no wake detection). |
Key Features
| Feature | Design Value |
|---|---|
| Split Termination Support | Internal SPLIT output drives external 60 Ω resistor center tap to maintain stable 2.5 V recessive common-mode voltage - reduces bus timing jitter and improves EMC immunity. |
| Multi-Source Wake-Up Detection | Simultaneous remote (bus activity) and local (WK pin edge) wake-up detection with source identification - enables precise root-cause logging in diagnostic trouble codes (DTCs). |
| Comprehensive Short-Circuit Diagnostics | Detects TxD-to-RxD short, CANH-to-GND, CANL-to-GND, CANH-to-CANL, and bus dominant clamping - reported via NERR without requiring external test equipment. |
| VIO/VCC/VS Under-Voltage Monitoring | Independent UVLO circuits on all three supplies trigger NERR assertion and force safe shutdown - prevents metastable operation during brown-out or battery disconnect. |
| Receive-Only Diagnostic Mode | Configurable via EN/NSTB to disable transmitter while retaining full receiver functionality - isolates faulty TX drivers during field failure analysis without disrupting bus communication. |
Applications
| Body Control Module (BCM) | Door Control Unit (DCU) |
|---|---|
|
Use Scenario: Centralized control of lighting, windows, locks, and mirrors in modern vehicles. IC Role / Device Role / Timing Role: HS-CAN physical layer interface between 32-bit ARM-based MCU and vehicle-wide CAN backbone.

Use Scenario: Sunroof open/close, tilt, and anti-pinch functions integrated with rain/light sensors. IC Role / Device Role / Timing Role: CAN transceiver with INH output controlling external 5 V LDO for sensor supply. Use Value: INH goes high-impedance in Sleep mode, disabling sensor power - eliminates parasitic draw from ambient light sensor during vehicle off-state. |
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 |
|---|---|---|---|
| MAX3051ESA+ | Single-supply (5 V only), no VIO separation, no wake-up inputs, no split termination output, no NERR diagnostic flag. | Lacks local wake-up, bus failure diagnostics, and mixed-voltage interface - suitable only for non-AEC-Q100 industrial CAN nodes. | Select when cost sensitivity outweighs automotive diagnostics and power architecture flexibility. |
| TJA1042T/3/1 | Pin-compatible but lacks INH output and split termination; includes standby mode with wake-up filtering; lower ESD (±6 kV). | No inhibit control for external regulators; reduced diagnostic granularity (no TxD timeout or RxD clamp detection). | Choose when existing PCB layout re-use is critical and INH functionality is unused in target design. |
Compared with MAX3051ESA+ and TJA1042T/3/1, the TLE62512GXUMA3 uniquely integrates VIO/VS separation, split termination, INH control, and comprehensive NERR-flagged diagnostics - making it the only option qualified for AEC-Q100 mixed-supply body electronics requiring deterministic failure reporting and ultra-low sleep current.

FAQ
What is the maximum allowable voltage on the VS pin during load dump conditions?
The VS pin is rated for continuous operation from 5 V to 27 V and withstands transient pulses per ISO 7637-2 Pulse 5a (60 V, 100 ms duration) without latch-up or parametric shift. External TVS clamping is not required if board layout follows Infineon's recommended decoupling and grounding practices outlined in Application Note AN2018-05.
Can the TLE62512GXUMA3 operate with VIO = 1.8 V while VS = 12 V?
Yes - VIO and VS are electrically isolated domains. The device supports VIO from 1.8 V to 5.5 V independently of VS (5–27 V). At VIO = 1.8 V, TxD input threshold is ~0.9 V and RxD output high-level voltage is ≥1.4 V, ensuring compatibility with 1.8 V microcontrollers such as the NXP S32K144.
How does the split termination function improve bus signal integrity?
The SPLIT pin drives the center tap of an external 60 Ω split termination (two 30 Ω resistors to VCC/2), stabilizing the recessive common-mode voltage at 2.5 V. This reduces differential skew caused by bus asymmetry and improves electromagnetic compatibility by lowering radiated emissions above 30 MHz by up to 6 dB compared to standard 120 Ω end-termination.
Is the TLE62512GXUMA3 pin-compatible with the legacy TLE6251G?
Yes - the TLE62512GXUMA3 is fully pin- and function-compatible with the TLE6251G, including identical pinout, electrical characteristics, and package (PG-DSO-14). Migration requires no PCB changes and provides improved passive behavior in Power Down mode and enhanced ESD robustness (±9 kV vs. ±6 kV).
