Product details

Overview

TLE9867QXA40XUMA1 from Infineon Technologies is an automotive-qualified Arm® Cortex®-M3 microcontroller integrating a LIN 2.2 transceiver, dual H-bridge MOSFET driver with charge pump, and high-speed op-amp for shunt-based motor current sensing. It operates from 5.5 V to 28 V, features 64 KB flash and 6 KB RAM, and supports junction temperatures from –40°C to +150°C - enabling direct integration in wiper, window lift, and tailgate actuator control modules.

For engineers reviewing the TLE9867QXA40XUMA1 datasheet, TLE9867QXA40XUMA1 pinout, TLE9867QXA40XUMA1 application, or TLE9867QXA40XUMA1 equivalent, this device delivers tightly coupled motor control, LIN communication, and on-chip power management in a single VQFN-48 package - critical for space-constrained, safety-conscious automotive body electronics designs.

Technical Context

The TLE9867QXA40XUMA1 implements a dedicated system architecture for brushed DC motor control: its SCU-PM unit manages gate drive timing and charge pump regulation for external N-channel MOSFETs, while the integrated LIN transceiver complies fully with ISO 17987-4 (LIN 2.2) for diagnostic and configuration messaging over single-wire bus. The high-speed op-amp (gain-bandwidth product >1 MHz) is internally routed to ADC inputs for real-time current feedback without external signal conditioning.

Power management includes three regulated supplies: 5.0 V (VDDP) for digital logic and peripherals, 1.5 V (VDDC) for the Cortex-M3 core, and an externally supplied 5.0 V (VDDEXT) for analog circuitry - all monitored by independent voltage supervisors and supported by watchdog timers (WDT1) with windowed operation for ASIL-B–capable fault handling.

Key Specifications

Parameter	Value and Actual Design Meaning
CPU Core	Arm® Cortex®-M3, 32-bit, up to 48 MHz - enables deterministic real-time motor control loop execution with <5 µs interrupt latency.
Memory	64 KB embedded flash (with ECC), 6 KB SRAM - sufficient for LIN stack, motor control firmware, and runtime variables without external memory.
LIN Interface	Integrated LIN 2.2 transceiver (ISO 17987-4 compliant), supports baud rates up to 20.0 kbps - eliminates need for discrete transceiver IC and reduces BOM count.

Window Lift Actuation

Use Scenario: Variable-speed windshield wiper with park position detection and rain-sensing interface.

IC Role / Device Role / Timing Role: Primary motor controller executing closed-loop speed regulation, LIN command parsing, and fault-safe shutdown.

Use Value: Integrated op-amp and CCU6 enable accurate current-based stall detection and smooth ramp-up/ramp-down without external analog components.

Use Scenario: Anti-pinch window lift system requiring torque monitoring and direction reversal on obstruction detection.

IC Role / Device Role / Timing Role: Real-time motor current sampling via shunt + op-amp, LIN-based ECU coordination, and H-bridge directional control.

Use Value: Sub-µs op-amp response and hardware-dead-time insertion prevent shoot-through during direction reversal under dynamic load.

Sunroof Sliding Mechanism

Tailgate Power Assist

Use Scenario: Bidirectional sunroof movement with soft-stop, obstacle detection, and position tracking via hall sensor interface.

IC Role / Device Role / Timing Role: LIN slave node managing motor sequencing, current limiting, and status reporting to body control module.

Use Value: On-chip 64 KB flash stores calibrated motor profiles and anti-jam algorithms; VQFN-48 thermal pad ensures reliability in confined headliner space.

Use Scenario: Power-assisted tailgate opening/closing with load-dependent speed control and end-position latching.

IC Role / Device Role / Timing Role: Standalone actuator controller handling LIN commands, motor current profiling, and thermal derating logic.

Use Value: 150°C-rated operation allows mounting inside tailgate latch assembly; integrated charge pump sustains gate drive during battery sag below 9 V.

Equivalent & Alternatives

The following parts are listed as comparable options for similar automotive brushed DC motor control applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STSPIN32F0B	Integrated 3-phase BLDC gate driver + Cortex-M0+, no LIN transceiver, 32 KB flash.	Targeted at BLDC fans/pumps; lacks LIN and high-temp rating for body actuators.	Select when BLDC control and compact size outweigh need for LIN diagnostics and AEC-Q100 Grade 0.
NXP S912ZVML12F1MKL	16-bit S12Z core, 128 KB flash, LIN 2.1 only, no integrated op-amp or charge pump.	Requires external op-amp and transceiver; higher flash but legacy architecture limits toolchain support.	Prefer for legacy S12Z migration paths where LIN 2.1 suffices and external analog integration is acceptable.

Compared with STSPIN32F0B and S912ZVML12F1MKL, the TLE9867QXA40XUMA1 uniquely combines LIN 2.2, 150°C operation, and shunt-sensing op-amp in one die - reducing total solution size and qualifying for next-gen automotive body domain controllers without architectural compromise.

FAQ

What LIN protocol versions does the TLE9867QXA40XUMA1 support?

The device integrates a fully compliant LIN 2.2 transceiver per ISO 17987-4, supporting standard and enhanced checksum models, auto-baud detection, and sleep/wake functionality. It does not support LIN 2.1 legacy frame formats or LIN 2.2A extensions such as configurable frame IDs beyond standard assignment tables.

Can the TLE9867QXA40XUMA1 drive P-channel high-side MOSFETs?

No - the integrated gate drivers are designed exclusively for N-channel MOSFETs, using an internal charge pump to generate gate voltages above VBAT for high-side switching. Driving P-channel devices would require external level-shifting circuitry and is not supported by the driver architecture or pin configuration.

Is the on-chip op-amp configurable for gain or filtering?

The op-amp has fixed internal gain (non-inverting, gain = 10) and no user-adjustable bandwidth or filter settings. Its output is hardwired to ADC0 input; gain and offset calibration must be performed in firmware using factory-trimmed parameters stored in OTP memory.

Does the TLE9867QXA40XUMA1 include hardware-based functional safety features?

Yes - it includes lockstep-capable watchdog timer (WDT1) with windowed mode, memory protection unit (MPU), ECC on flash, and voltage/temperature monitors with fail-safe interrupt generation. These meet ASIL-B requirements per ISO 26262 when implemented per Infineon's safety manual (AN512).
