Product details

Overview

TLE9274QXXUMA3 from Infineon Technologies is a high-end automotive System Basis Chip (SBC) integrating 5 V/750 mA SMPS buck regulator, 5 V/100 mA LDO with off-board protection, DC/DC boost converter for low-battery operation, HS-CAN FD transceiver compliant to ISO 11898-2:2016 (up to 5 Mbps), and up to four LIN 2.2/J2602 transceivers - all in a single PG-VQFN-48 package. It serves as central power management and communication interface in body control modules and gateways.

For engineers reviewing the TLE9274QXXUMA3 datasheet, TLE9274QXXUMA3 pinout, TLE9274QXXUMA3 application, or TLE9274QXXUMA3 equivalent, key selection criteria include CAN FD timing compliance, multi-LIN configurability, cyclic wake capability in Stop mode, and AEC-Q100 qualification for permanent battery-connected automotive systems.

Technical Context

The device implements a hierarchical state machine with six operational modes (Init, Normal, Stop, Sleep, Restart, Fail-Safe), each with distinct power regulation and bus activity profiles. Its SMPS buck operates in PWM/PSM hybrid mode during Stop mode to maintain ultra-low quiescent current (< 30 µA typical), while the boost converter enables operation down to 4.5 V battery input.

Communication interfaces are fully decoupled: the HS-CAN transceiver supports Wake-Capable and Receive-Only modes with TXD timeout and bus dominant clamping; each LIN transceiver includes programmable TXD timeout, Flash mode, and slope selection - all configurable via 16-bit SPI interface with status registers for real-time supervision.

Key Specifications

Parameter	Value and Actual Design Meaning
SMPS Buck Output	5 V / 750 mA - powers MCU core and high-current peripherals with >90% efficiency at 1 A load
LDO Output	5 V / 100 mA - protected output for off-board sensors with short-circuit and thermal shutdown
CAN FD Data Rate	Up to 5 Mbps - meets ISO 11898-2:2016 physical layer requirements for high-speed automotive networks
LIN Transceivers	4 × LIN 2.2 / SAE J2602 - supports mixed topology with independent TXD timeout and Flash programming mode per channel
Quiescent Current (Stop)	28 µA typical - enables always-on functionality in gateway ECUs without excessive battery drain
Operating Voltage Range	4.5 V to 28 V - accommodates cold-crank (4.5 V) and load-dump (28 V) conditions per ISO 7637-2
Package	PG-VQFN-48 (7 mm × 7 mm) with exposed thermal pad - enables high-power dissipation and AOI-compatible Lead Tip Inspection

Pinout & Package

PG-VQFN-48 (7 mm × 7 mm) leadless package with exposed thermal pad and Lead Tip Inspection (LTI) feature for automated optical inspection. Pin functions validated per Infineon datasheet Rev. 2.0 (2022-05-06), Section 3.2.

Pin/Terminal	Circuit Role	Design Meaning
VCC_BUCK	Buck regulator input	Primary supply input (4.5–28 V) for SMPS buck stage; requires external input capacitor and inductor
VOUT_BUCK	Buck regulator output	Stabilized 5 V / 750 mA output; connects directly to MCU VDD and high-current loads
VREG2	LDO output	5 V / 100 mA regulated output with overcurrent and thermal protection for sensor rails
CANH / CANL	CAN FD differential pair	High-speed CAN physical layer interface supporting wake-up pattern detection and bus fault tolerance
LIN1–LIN4	LIN transceiver channels	Four independent LIN bus interfaces, each with TXD, RXD, and EN pins; support LIN Flash mode for firmware updates
WAKE_IN	Bi-level wake input	Configurable voltage-level monitoring input enabling wake from Stop/Sleep on external signal edge or level change
SPI_MOSI / MISO / SCLK / CSN	SPI interface	16-bit serial peripheral interface for configuration, status readback, and watchdog control
FS_OUT1–FS_OUT3	Fail-safe outputs	Three programmable open-drain outputs activated in Fail-Safe mode to drive external relays or warning indicators

Key Features

Feature	Design Value
Cyclic wake in Stop mode	Programmable interval (1 ms to 65 s) enables periodic self-checks without host MCU intervention
Boost converter operation	Extends functional operation down to 4.5 V battery input - critical for cold-crank scenarios in engine start
Fail-safe input monitoring	Dedicated FS_IN pin monitors MCU hardware integrity; triggers Fail-Safe mode if MCU fails to toggle within window
Configurable watchdog	Timeout/window watchdog with reset output and SPI-accessible status register for diagnostic logging
RoHS-compliant green product	Meets EU Directive 2011/65/EU; halogen-free and lead-free per JEDEC JS709C standards

Applications

Body Control Module (BCM)

Automotive Gateway

Use Scenario: Centralized control of door locks, lighting, wipers, and mirrors in modern vehicle architectures.

IC Role / Device Role / Timing Role: Primary power source (5 V SMPS + LDO) and dual-bus interface (CAN FD + 4×LIN) coordinating distributed nodes.

Use Value: Reduces BOM count by consolidating power regulation and communication into one AEC-Q100-qualified IC, lowering system cost and PCB area.

Use Scenario: Aggregation and routing of messages between powertrain, chassis, and infotainment domains.

IC Role / Device Role / Timing Role: High-speed CAN FD backbone interface with LIN sub-network bridging and fail-safe fallback signaling.

Use Value: Enables deterministic 5 Mbps CAN FD throughput while maintaining legacy LIN compatibility - essential for E/E architecture scalability.

HVAC ECU

Seat Control Unit

Use Scenario: Climate control system managing blower motors, temperature sensors, and damper actuators.

IC Role / Device Role / Timing Role: Power manager for HVAC MCU and LIN master for cabin sensor network (temperature, humidity, air quality).

Use Value: LDO's off-board protection ensures stable 5 V supply to analog sensors; LIN Flash mode allows in-vehicle firmware updates.

Use Scenario: Motorized seat position memory, heating, and massage functions requiring precise actuator coordination.

IC Role / Device Role / Timing Role: Local power source and LIN slave interface for seat switch panels and position sensors.

Use Value: Ultra-low Stop-mode current (<30 µA) prevents battery drain during vehicle standby; cyclic wake enables periodic seat position verification.

Equivalent & Alternatives

The following parts are listed as comparable options for similar System Basis Chip applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLE9273QXXUMA3	Same 4-LIN, SMPS buck, and CAN FD architecture but with 2-configuration boost output (vs. 3 in TLE9274QX)	Limited boost flexibility for low-voltage battery recovery; suitable where only two boost thresholds are needed	Select when full 3-threshold boost configurability is unnecessary and cost optimization is prioritized
TLE9274QXV33	Identical feature set but with 3.3 V main SMPS output instead of 5 V; same PG-VQFN-48 package	Targets 3.3 V MCU platforms (e.g., ARM Cortex-M7); not interchangeable without power rail redesign	Choose only when system MCU requires 3.3 V supply and board layout supports voltage rail change

Compared with TLE9273QXXUMA3, the TLE9274QXXUMA3 provides greater boost voltage flexibility for extended low-battery operation; versus TLE9274QXV33, it delivers higher 5 V output current for legacy MCU and sensor compatibility - making it optimal for 5 V-centric gateway and BCM designs.

FAQ

What automotive qualification does TLE9274QXXUMA3 meet?

TLE9274QXXUMA3 is qualified per AEC-Q100 Grade 1 (−40 °C to +125 °C ambient), including stress testing for temperature cycling, humidity bias, and ESD (±2 kV HBM). It also complies with ISO 7637-2 for transient immunity and ISO 11898-2 for CAN FD physical layer robustness - confirmed in Infineon's official qualification report SP005729430.

Can TLE9274QXXUMA3 operate with a 3.3 V microcontroller?

Yes - while its primary SMPS output is 5 V, the device includes a dedicated 5 V/100 mA LDO (VREG2) that can power external 3.3 V LDOs or level-shifters. The SPI interface operates at 1.8–5.5 V logic levels, and the MCU I/Os connect directly to LIN/CAN transceivers without voltage translation.

How is wake-up handled across different low-power modes?

Wake sources include CAN/LIN message detection, bi-level WAKE_IN pin, and programmable cyclic timer - all active in Stop and Sleep modes. In Stop mode, wake latency is <100 µs; in Sleep mode, it is <10 µs. The wake source is latched and reported via SPI status register bits WAKE_SRCx before mode transition completes.

Does TLE9274QXXUMA3 support LIN firmware updates over the bus?

Yes - all four LIN transceivers support LIN Flash mode per LIN 2.2 specification. This enables in-system programming of connected slave nodes using standardized UDS-over-LIN services (e.g., SID 0x31), with TXD timeout and error recovery managed autonomously by the SBC.
