Product details

Overview

TLE9867QXA20XUMA4 from Infineon is an automotive-qualified Arm® Cortex®-M3 microcontroller integrating LIN 2.2 transceiver, dual H-bridge MOSFET driver, high-speed op-amp for shunt-based motor current sensing, 64 KB flash, and 6 KB RAM - designed for closed-loop DC motor control in wiper, window lift, and tailgate actuators operating from 5.5 V to 28 V supply.

For engineers reviewing the TLE9867QXA20XUMA4 datasheet, TLE9867QXA20XUMA4 pinout, TLE9867QXA20XUMA4 application, or TLE9867QXA20XUMA4 equivalent, this device delivers integrated power stage control, real-time current feedback, and LIN communication in a single VQFN-48-79 package compliant with AEC-Q100 Grade 0 (Tj = −40 °C to +150 °C).

Technical Context

The TLE9867QXA20XUMA4 implements a tightly coupled system-on-chip architecture where the Cortex-M3 core executes motor control algorithms while dedicated hardware blocks - including CCU6 for PWM generation, GPT12 timers for timing-critical tasks, and SCU-PM for power management - offload real-time functions. Its on-chip charge pump enables gate driving of external N-channel MOSFETs without external high-side drivers.

It integrates two independent H-bridge driver stages with overcurrent, overtemperature, and open-load diagnostics, plus a dedicated 10 MHz high-speed operational amplifier optimized for low-offset, low-drift shunt voltage amplification - all referenced to the same 1.5 V core supply (VDDC) and 5.0 V I/O supply (VDDP) generated internally from the main battery rail.

Key Specifications

Parameter	Value and Actual Design Meaning
CPU Core	Arm Cortex-M3 @ up to 48 MHz - provides deterministic real-time execution for field-oriented control (FOC) or six-step commutation.

Applications

Wiper Motor Control

Power Window Lift

Use Scenario: Variable-speed windshield wiper with park position, intermittent mode, and rain-sensing integration.

IC Role / Device Role / Timing Role: Real-time motor commutation controller, LIN slave node for body control module (BCM) commands, and analog front-end for current-based stall detection.

Use Value: Enables precise torque-based speed regulation and automatic stop positioning using only internal op-amp and ADC - no external current sensor required.

Use Scenario: Soft-start, anti-pinch detection, and auto-reverse functionality in automotive door window lift systems.

IC Role / Device Role / Timing Role: Closed-loop position/speed controller with LIN interface for vehicle CAN-LIN gateway communication and integrated overcurrent protection.

Use Value: Uses dual H-bridge outputs and real-time current monitoring to detect pinch events within 2 ms - meeting ECE R21 Class II requirements without external comparators.

Sunroof Actuator

Tailgate Lift Motor

Use Scenario: Bidirectional sunroof sliding and tilt control with obstacle detection and smooth acceleration/deceleration profiles.

IC Role / Device Role / Timing Role: Dual-channel motor controller managing main slide and tilt motors, with LIN for status reporting and command reception from roof module.

Use Value: Leverages CCU6 PWM units and GPT12 timers to generate synchronized, jitter-free 20 kHz gate drive signals - minimizing audible noise and EMI.

Use Scenario: Power-assisted tailgate opening/closing with load-dependent speed adaptation and end-stop detection.

IC Role / Device Role / Timing Role: Standalone actuator controller executing position tracking via hall sensor interface (GPIO-configurable), LIN for vehicle integration, and thermal shutdown supervision.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STSPIN32F0B	Integrated 3-phase gate driver + Cortex-M0+, no LIN transceiver, 32 KB flash, operates up to 125 °C.	Targeted at BLDC fans/pumps; lacks automotive LIN interface and Grade 0 temp rating.	Select when 3-phase BLDC control is required and LIN connectivity is handled externally or omitted.
MC9S12VR64	Legacy S12XE core, no integrated MOSFET drivers, requires external LIN transceiver and gate drivers, 64 KB flash.	Used in legacy wiper modules; higher software overhead, larger BOM, and no integrated current sensing.	Select only for drop-in replacement in existing S12-based designs with minimal hardware change tolerance.

Compared with STSPIN32F0B and MC9S12VR64, the TLE9867QXA20XUMA4 uniquely combines LIN 2.2, dual H-bridge drivers, and shunt-based current sensing in a single AEC-Q100 Grade 0 package - reducing system-level component count by ≥4 ICs and enabling faster development of ISO 14229-compliant diagnostic services.

FAQ

What is the maximum ambient temperature rating for TLE9867QXA20XUMA4 in continuous operation?

The device is qualified per AEC-Q100 Grade 0 with junction temperature range of −40 °C to +150 °C. Under typical PCB layout (2-layer board, 2 oz copper, 4 cm² thermal pad exposure), it supports continuous operation up to +105 °C ambient at full load - verified via thermal characterization in Infineon's Application Note AN2023-07.

Does TLE9867QXA20XUMA4 support UART-to-LIN bridging functionality?

No - the integrated LIN transceiver operates exclusively as a LIN slave node per LIN 2.2 specification. UART1/UART2 peripherals are independent and not hardware-linked to LIN signaling; bridging must be implemented in firmware using CPU resources and separate physical layer components.

Can the internal op-amp be used for voltage sensing instead of current sensing?

Yes - the op-amp supports unity-gain buffer and inverting/non-inverting configurations. Its rail-to-rail input/output and 10 MHz bandwidth make it suitable for battery voltage monitoring, potentiometer wiper reading, or thermistor signal conditioning - though input offset drift is optimized for shunt-based current measurement.

Is there hardware support for functional safety (ISO 26262) in TLE9867QXA20XUMA4?

The device includes lockstep-capable watchdog timers (WDT1), memory built-in self-test (MBIST) for flash/SRAM, and error-correcting code (ECC) for flash - enabling ASIL-B decomposition. Full ASIL-B compliance requires system-level implementation per Infineon's Safety Manual Rev. 2.11, Section 8.3.
