Product details
Overview
TLE9273QXV33 from Infineon is a high-end automotive System Basis Chip (SBC) integrating 3.3 V/750 mA SMPS buck regulator, 5 V/100 mA LDO, DC/DC boost converter, HS-CAN FD transceiver (ISO 11898-2:2016, up to 5 Mbps), and up to four LIN transceivers - all in a single PG-VQFN-48 package. It serves as the central power and communication hub for microcontrollers in body control modules and gateways.
For engineers reviewing the TLE9273QXV33 datasheet, TLE9273QXV33 pinout, TLE9273QXV33 application, or TLE9273QXV33 equivalent, key selection criteria include CAN FD data rate support, configurable cyclic wake capability in Stop/Sleep modes, fail-safe output activation logic, and AEC-Q100 qualification for permanent battery-connected automotive ECUs.
Technical Context
The device implements a hierarchical state machine with six operational modes (Normal, Stop, Sleep, Restart, Fail-Safe, Development), each with distinct power sequencing, bus activity, and supervision behavior. Its SPI interface enables full configuration of watchdog timeout windows, LIN TXD timeout, wake-source sensitivity, and fail-safe output mapping.
Power regulation combines synchronous buck (3.3 V, 750 mA), low-dropout linear (5 V, 100 mA, off-board protected), and boost converter (for battery voltages down to 3.0 V). The CAN FD transceiver supports Wake-capable mode with pattern detection, while LIN transceivers comply with LIN 2.2 and SAE J2602, including Flash mode for firmware updates.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.5 V to 28 V input - supports wide automotive battery range including cold-crank (4.5 V) and load-dump (28 V) conditions. |
| Buck Regulator Output | 3.3 V ±2%, 750 mA - powers MCU core and high-current peripherals with >90% efficiency at mid-load. |
| LDO Output | 5 V ±3%, 100 mA - supplies sensors or external ICs with reverse-polarity and short-circuit protection. |
| CAN FD Data Rate | Up to 5 Mbps - enables high-bandwidth gateway communication compliant with ISO 11898-2:2016. |
| LIN Transceivers | Up to 4 independent channels - supports multi-node LIN clusters (e.g., HVAC actuators + door modules) with programmable TXD timeout. |
| Quiescent Current | ≤ 20 µA in Sleep mode - enables always-on functionality without excessive battery drain over weeks. |
| Operating Temperature | −40 °C to +150 °C - qualified per AEC-Q100 Grade 0 for under-hood and transmission-control applications. |
Pinout & Package
Package: PG-VQFN-48 (7 mm × 7 mm), leadless exposed-pad with Lead Tip Inspection (LTI) feature for AOI compatibility and thermal enhancement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VBAT | Main battery supply input | Accepts 4.5–28 V; feeds internal regulators and wake detection circuitry. |
| V33OUT | SMPS buck output | 3.3 V regulated supply for MCU core and digital logic; requires external LC filter. |
| V5OUT | LDO output | 5 V sensor supply with overcurrent foldback and thermal shutdown. |
| CANH / CANL | CAN FD differential bus interface | Direct connection to CAN bus; supports Normal, Receive-Only, and Wake-capable modes via SPI control. |
| LIN1–LIN4 | Independent LIN transceiver channels | Each supports LIN 2.2 frame handling, slope control, and TXD timeout; configurable via SPI register map. |
| WAKE | Bi-level sensitive wake input | Detects voltage thresholds (e.g., 3.3 V or 5 V logic) to exit Stop/Sleep modes without bus activity. |
| FSO1–FSO3 | Fail-safe outputs | Open-drain outputs activated during Fail-Safe mode to drive external relays or warning indicators. |
| RESET | Reset output | Active-low, synchronized to internal watchdog timeout or undervoltage condition. |
Key Features
| Feature | Design Value |
|---|---|
| Configurable cyclic wake | Enables periodic wake-up from Stop/Sleep modes at user-defined intervals (e.g., 100 ms–10 s) for sensor polling without host MCU intervention. |
| Timeout/window watchdog | Programmable windowed watchdog with independent enable/disable per mode; reset pulse duration configurable via SPI. |
| Fail-safe input monitoring | Dedicated FSI pin monitors MCU health; triggers Fail-Safe mode if signal is missing or stuck for >100 ms. |
| Boost converter operation | Activates automatically below 6.5 V battery input to maintain V33OUT stability - critical for start-stop systems. |
| SPI register access | 16-bit SPI interface with CRC-8 error checking enables real-time status readback (e.g., temperature, voltage flags, fault latches). |
Applications
| Body Control Module (BCM) | Automotive Gateway |
|---|---|
Use Scenario: Centralized control of lighting, door locks, and window motors in modern vehicle architectures. IC Role / Device Role / Timing Role: Primary power source (3.3 V MCU supply + 5 V sensor rail) and dual-bus interface (CAN FD backbone + LIN subnetworks). Use Value: Reduces BOM count by consolidating power regulation and bus transceivers; enables ultra-low sleep current (<20 µA) for extended battery life. |
Use Scenario: High-speed routing between CAN FD domains (powertrain, ADAS) and legacy LIN subsystems (climate, seats). IC Role / Device Role / Timing Role: CAN FD transceiver (5 Mbps) and up to four LIN transceivers operate concurrently under SPI-coordinated timing control. Use Value: Eliminates need for discrete CAN/LIN level shifters and external regulators; supports simultaneous bus arbitration and wake propagation. |
| HVAC ECU | Steering Column Control Unit |
Use Scenario: Climate control unit managing blower motor, temperature sensors, and actuator feedback across multiple LIN nodes. IC Role / Device Role / Timing Role: LIN master with Flash mode support for firmware updates; 5 V LDO powers NTC thermistors and Hall-effect position sensors. Use Value: LIN TXD timeout prevents bus lockup during actuator stall; boost converter sustains operation during engine cranking (VBAT dips to 4.5 V). |
Use Scenario: Compact module integrating steering angle, torque, and button inputs with CAN FD reporting to EPS and ADAS domains. IC Role / Device Role / Timing Role: Fail-safe output drives EPS warning lamp on FSI loss; cyclic wake polls button states every 500 ms in Stop mode. Use Value: Enables functional safety compliance (ASIL-B capable) via hardware-monitored fail-safe path and deterministic watchdog behavior. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar System Basis Chip applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLE9273QX | Outputs 5 V (not 3.3 V) from main SMPS; identical pinout, SPI register map, and feature set. | Used where MCU requires 5 V core supply instead of 3.3 V; not suitable for 3.3 V-only MCUs without external LDO. | Select when system architecture mandates 5 V MCU rail and no secondary 3.3 V regulator is present. |
| TLE9274QXV33 | Adds third SMPS output (configurable 3.3/5.0/5.5 V); same 4-LIN, CAN FD, and fail-safe features. | Supports triple-rail systems (e.g., MCU + FPGA + analog sensor ASIC); higher pin count (VQFN-64) and cost. | Choose when additional regulated rail is required beyond V33OUT and V5OUT - avoids external DC/DC. |
Compared with TLE9273QXV33, TLE9273QX shifts primary regulation to 5 V (requiring external 3.3 V LDO for compatible MCUs), while TLE9274QXV33 adds a third programmable SMPS output but increases footprint and complexity - making TLE9273QXV33 optimal for cost-sensitive, 3.3 V MCU-centric designs with dual-rail needs.

FAQ
What is the maximum ambient temperature supported by TLE9273QXV33 in continuous operation?
The device is qualified per AEC-Q100 Grade 0 with guaranteed operation from −40 °C to +150 °C junction temperature. Under typical PCB layout (2-layer, 2 oz Cu, 4 cm² exposed pad copper), it sustains continuous 750 mA buck output at +105 °C ambient with ≤10 K rise - validated via thermal imaging and lifetime testing.
Does TLE9273QXV33 support partial networking or selective wake-up on individual LIN channels?
No - wake-up is global across all LIN transceivers. The device supports only system-wide wake events: CAN message reception, WAKE pin assertion, or cyclic timer expiration. Individual LIN channel disable is possible via SPI, but no per-channel wake detection is implemented.
Can the boost converter be disabled to reduce quiescent current in Sleep mode?
Yes - the boost converter is automatically disabled in Sleep mode and remains inactive until VBAT drops below 6.5 V in Normal or Stop mode. In Sleep mode, only the buck regulator and LDO remain powered (if enabled), contributing to the ≤20 µA total quiescent current.
Is SPI communication functional during SBC Stop mode?
No - SPI is disabled in Stop mode to minimize leakage. Configuration must be completed in Normal or Development mode before entering Stop. Status registers retain values, but no SPI read/write is possible until transition back to Normal mode via wake event.
