Product details
Overview
TLE94613ESV33XUMA1 from Infineon Technologies is a monolithic System Basis Chip (SBC) for automotive CAN FD networks, integrating a 3.3 V/150 mA LDO main regulator, 5 V/100 mA auxiliary regulator with off-board protection, HS-CAN transceiver compliant with ISO 11898-2:2016 and SAE J2284, SPI interface, configurable watchdog, and fail-safe output - deployed in HVAC ECUs, seat control modules, and smart power distribution units.
For engineers reviewing the TLE94613ESV33XUMA1 datasheet, TLE94613ESV33XUMA1 pinout, TLE94613ESV33XUMA1 application, or TLE94613ESV33XUMA1 equivalent, key selection considerations include CAN FD partial networking support, cyclic wake/sense capability in Stop/Sleep modes, spread spectrum modulation for EMC optimization, and AEC-Q100 qualification for permanent battery-connected automotive subsystems.
Technical Context
The device implements a multi-state SBC state machine (Normal, Stop, Sleep, Restart, Fail-Safe, Development) with bi-level wake input, periodic Cyclic Wake and Cyclic Sense functions, and selective wake (SWK) via CAN bus pattern detection. It supports CAN FD tolerant mode and Partial Networking to reduce system-wide quiescent current.
Its dual LDO architecture supplies both microcontroller (3.3 V, 150 mA continuous) and sensors/peripherals (5 V, 100 mA), while the integrated charge pump enables N-channel MOSFET reverse-polarity protection. All modes feature overtemperature and short-circuit protection, and the TEST pin allows entry into Development Mode with watchdog suspension.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CAN Data Rate | Up to 5 Mbit/s - enables high-bandwidth CAN FD communication in modern automotive domain controllers. |
| Main Regulator Output | 3.3 V / 150 mA (250 mA peak) - powers 32-bit automotive MCUs with sufficient headroom for transient loads. |
| Auxiliary Regulator Output | 5 V / 100 mA - supplies off-board sensors with integrated overvoltage/overcurrent protection. |
| Quiescent Current (Sleep Mode) | < 20 µA - minimizes battery drain in always-on vehicle modules like trunk controllers. |
| Operating Voltage Range | 4.5 V to 28 V - withstands cold-crank (4.5 V) and load-dump (28 V) conditions per ISO 16750-2. |
| Temperature Range | −40 °C to +150 °C - qualified for under-hood and cabin-mounted ECU placement. |
| EMC Performance | Spread spectrum modulation on charge pump - reduces peak radiated emissions for CISPR 25 Class 5 compliance. |
Pinout & Package
Package: PG-TSDSO-24-1 (exposed pad, 150 mil), RoHS-compliant, thermally optimized for automotive PCB layouts with direct thermal path to copper pour.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Main supply input | Accepts 4.5–28 V battery rail; feeds internal regulators and CAN transceiver. |
| VDDIO | Digital I/O supply | Provides 3.3 V logic supply for SPI interface and GPIOs; decoupled separately for noise immunity. |
| VSUP | Regulated 3.3 V output | Delivers up to 150 mA to MCU core; includes undervoltage reset and short-circuit foldback. |
| V5V | Regulated 5 V output | Supplies external sensors; features overvoltage lockout and current limiting for off-board robustness. |
| CANH / CANL | CAN bus differential pair | HS-CAN physical layer interface supporting FD and Partial Networking; integrated common-mode choke drive. |
| SPI_MOSI / SPI_MISO / SPI_SCK / SPI_CS | SPI communication interface | 16-bit full-duplex SPI for configuration, status readback, and diagnostic register access. |
| WAKE | Bi-level wake input | Detects voltage thresholds (e.g., 12 V/24 V) to initiate wake from Stop/Sleep without CAN traffic. |
| FAIL | Fail-safe output | Open-drain signal asserted during overtemperature, regulator fault, or watchdog timeout - drives external safety logic. |
| TEST | Development mode entry | Pulled low at power-up to suspend watchdog and enable debug configuration via SPI. |
Key Features
| Feature | Design Value |
|---|---|
| Cyclic Wake in Sleep Mode | Enables periodic bus monitoring without full wake - reduces average current by >90% vs. continuous listen mode. |
| CAN Partial Networking Support | Allows selective node wake-up via targeted WUP/WUF frames - eliminates unnecessary network-wide wake events. |
| Spread Spectrum Modulation | Integrated on charge pump clock - lowers EMI peaks by spreading energy across 200 kHz bandwidth, easing EMC certification. |
| Configurable Window Watchdog | Programmable timeout (0.5 ms to 10 s) and window size - prevents runaway code while tolerating deterministic delays. |
| High-Voltage GPIO (HVIO) | Configurable as wake input, fail output, high-side switch, or low-side switch - replaces discrete HV drivers in compact ECUs. |
Applications
| HVAC ECU | Seat Control Module |

Equivalent & Alternatives
The following parts are listed as comparable options for similar System Basis Chip applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLE9461-2ES V33 | Lacks CAN Partial Networking and Cyclic Sense; identical 3.3 V/150 mA regulator and 5 V/100 mA auxiliary LDO. | Suitable only for non-networked or fully awake systems - cannot support selective wake in body domain architectures. | Select when cost sensitivity outweighs partial networking requirement and system design uses global wake instead of message-triggered wake. |
| TLE9263-3QX | Same SBC architecture but with 5 V main regulator (not 3.3 V); supports LIN alongside CAN; different SPI register map. | Targeted at mixed LIN/CAN nodes (e.g., mirror controls); not drop-in compatible due to voltage mismatch and protocol differences. | Choose only when migrating from legacy 5 V MCU platforms or adding LIN slave functionality - requires firmware and layout changes. |
Compared with TLE9461-2ES V33, this part adds critical CAN Partial Networking and Cyclic Sense for battery-sensitive applications; versus TLE9263-3QX, it delivers native 3.3 V MCU supply and simplified CAN-only integration - making it optimal for next-gen 3.3 V automotive domain controllers.

FAQ
What is the maximum allowable input voltage for TLE94613ESV33XUMA1?
The absolute maximum input voltage at VCC is 32 V, but the functional operating range is 4.5 V to 28 V per ISO 16750-2. Operation above 28 V is permitted only for ≤200 ms during load-dump events, with internal clamping protecting internal circuitry. Sustained operation beyond 28 V risks permanent damage.
Does TLE94613ESV33XUMA1 support CAN FD Classic fallback mode?
Yes - the integrated HS-CAN transceiver operates in CAN FD tolerant mode per ISO 11898-2:2016, allowing seamless interoperability with legacy CAN 2.0B nodes on the same bus. It automatically detects bit rate and frame format, transmitting and receiving both FD and Classic frames without software reconfiguration.
How is the fail-safe output (FAIL pin) triggered?
The FAIL pin asserts low during overtemperature (>175 °C), main regulator undervoltage (<2.7 V), watchdog timeout, or critical SPI configuration error. It remains active until cleared via SPI command or power cycle, and supports open-drain pull-up to 5 V or 3.3 V for direct connection to MCU interrupt or safety relay drivers.
Can the 5 V auxiliary regulator power external CAN transceivers?
No - the 5 V regulator (V5V) is rated for 100 mA with integrated overvoltage and overcurrent protection, intended for sensors and low-power peripherals. External CAN transceivers require separate 5 V supply meeting ISO 11898-2 drive strength and fault protection specs; using V5V for this purpose violates derating guidelines and voids AEC-Q100 compliance.
