Product details
Overview
TLE9273QXXUMA2 from Infineon Technologies is a high-end automotive System Basis Chip (SBC) integrating 5 V/750 mA SMPS buck regulator, HS-CAN FD transceiver (ISO 11898-2:2016, up to 5 Mbps), four LIN 2.2 transceivers, DC/DC boost converter, and dual LDOs - designed as main power and communication hub for body control modules and gateways.
For engineers reviewing the TLE9273QXXUMA2 datasheet, TLE9273QXXUMA2 pinout, TLE9273QXXUMA2 application, or TLE9273QXXUMA2 equivalent, key selection criteria include CAN FD timing compliance, cyclic wake capability in Stop mode, fail-safe output configuration, and SPI-controlled supervision features for AEC-Q100-compliant ECU designs.
Technical Context
The device implements a hierarchical state machine with five operational modes (Normal, Stop, Sleep, Restart, Fail-Safe), each with distinct power management and bus activity rules. Supervision includes configurable timeout/window watchdog, undervoltage reset, and fail-safe input monitoring with up to three programmable fail-safe outputs.
Its dual-regulator architecture combines a high-efficiency 750 mA buck SMPS (5 V) and a protected 5 V/100 mA LDO for off-board sensor supply, plus a boost converter supporting operation down to 4.5 V battery input. All regulators feature overtemperature and short-circuit protection.

Applications
| Body Control Module (BCM) | Automotive Gateway |
|---|---|
Use Scenario: Centralized control of door locks, lighting, window lifts, and interior sensors in 12 V/24 V vehicles. IC Role / Device Role / Timing Role: Primary power source (5 V/750 mA buck) and communication hub (CAN FD + 4×LIN) for distributed nodes. Use Value: Reduces BOM count by integrating power regulation, bus interfaces, and supervision - simplifies PCB layout and meets AEC-Q100 Grade 1 requirements. |
Use Scenario: Protocol translation between CAN FD backbone and multiple LIN subnetworks in modern vehicle architectures. IC Role / Device Role / Timing Role: High-speed CAN FD transceiver (5 Mbps) with synchronized LIN cluster management and SPI-configurable message routing. Use Value: Enables deterministic latency for OTA updates and diagnostic sessions across mixed-protocol domains without external level shifters or isolators. |
| HVAC Control Panel | Seat Control ECU |
Use Scenario: Power and communication interface for climate control units with touch displays and motorized actuators. IC Role / Device Role / Timing Role: Supplies 5 V/100 mA protected LDO for display backlight and sensors; uses LIN for actuator feedback and CAN for HVAC system coordination. Use Value: Off-board LDO protection prevents reverse-current damage during hot-plug sensor replacement - improves serviceability and field reliability. |
Use Scenario: Compact seat module managing position memory, heating, and massage functions with LIN-connected motors and CAN-linked vehicle network. IC Role / Device Role / Timing Role: Dual-regulator supply (buck for MCU, LDO for analog sensors) and simultaneous CAN FD + LIN2.2 communication with fail-safe output for heater cutoff. Use Value: Integrated fail-safe outputs activate thermal shutdown of seat heaters upon MCU failure - satisfies ISO 26262 ASIL-B functional safety requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar System Basis Chip applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLE9274QXXUMA2 | Same pinout and software compatibility; adds third SMPS output (3.3 V) and extended boost voltage options (3.3 V/5 V/9 V). | Required when MCU or peripheral ICs demand 3.3 V supply alongside 5 V - not needed for 5 V-only designs. | Select TLE9274 if multi-rail power delivery is required; otherwise TLE9273 offers cost and footprint advantage. |
| TLE9272QXXUMA2 | Reduces LIN count to 3 channels; retains identical buck, boost, CAN FD, and supervision features. | Suitable for simpler ECUs where one LIN channel is redundant - e.g., non-clustered seat or mirror modules. | Choose TLE9272 only when LIN channel count can be reduced without compromising functionality; maintains same thermal and electrical behavior. |
Compared with TLE9274QXXUMA2 and TLE9272QXXUMA2, the TLE9273QXXUMA2 delivers optimal balance of 4-LIN flexibility, single 5 V SMPS efficiency, and compact PG-VQFN-48 packaging - making it the preferred choice for mid-tier automotive gateways and BCMs requiring full LIN cluster support without extra voltage rails.

FAQ
What is the maximum ambient temperature rating for continuous operation?
The TLE9273QXXUMA2 is qualified per AEC-Q100 Grade 1 (−40 °C to +125 °C ambient), with junction temperature limited to 160 °C by internal thermal shutdown. Under typical PCB layout (2-layer, 2 oz copper, 4 cm² thermal pad area), it sustains full 750 mA buck load at +105 °C ambient with 25 K/W effective thermal resistance.
Does the device 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 via CAN message, WAKE pin assertion, or cyclic timer. Individual LIN channel disablement is possible via SPI register control, but no per-channel wake detection is implemented.
Can the boost converter operate independently of the buck regulator?
Yes - the boost converter (VSUP path) functions autonomously during low-battery conditions (down to 4.5 V) even when the buck regulator is disabled in Stop/Sleep modes. Its output supplies internal logic and wake circuitry, enabling reliable startup after deep discharge.
How is fail-safe output behavior configured during MCU reset?
FSO states are controlled by SPI-accessible registers (FSOx_CTRL) and default to high-impedance on power-up. After MCU initialization, they can be set to active-low or active-high, with automatic deactivation upon watchdog timeout or undervoltage event - behavior is fully programmable and non-latching unless explicitly configured.
