Product details

Overview

TLE9867QXW20XUMA3 from Infineon is an automotive-qualified Arm® Cortex®-M3 microcontroller integrating a LIN 2.2 transceiver, 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 extended junction temperature up to +175°C - enabling direct integration in under-hood wiper, window lift, and tailgate actuator modules.

For engineers reviewing the TLE9867QXW20XUMA3 datasheet, TLE9867QXW20XUMA3 pinout, TLE9867QXW20XUMA3 application, or TLE9867QXW20XUMA3 equivalent, this device delivers tightly coupled motor control with on-chip clock generation (OSC + PLL), integrated power regulation (VDDP 5.0 V, VDDC 1.5 V), and AEC-Q100 Grade 0 qualification for harsh automotive environments.

Technical Context

The TLE9867QXW20XUMA3 implements a dedicated system architecture for brush DC motor control: its SCU-PM unit manages gate driving via integrated charge pump and current-sense amplification, while the SCU-DM unit provides clock synthesis with dual oscillator modes (low-precision RC and high-precision crystal/external input). The LIN 2.2 transceiver is fully compliant and supports wake-up via bus activity.

It integrates three timer subsystems - GPT12 (two 16-bit timers), Timer2/Timer21 (dedicated for PWM generation), and CCU6 (capture/compare unit optimized for motor commutation) - all synchronized to the same clock domain and accessible via DMA for low-CPU-overhead real-time control loops.

Applications

Front-Windshield Wiper System

Electric Window Lift Module

Use Scenario: Precise speed and position control of 12 V DC wiper motor across variable load (ice, rain, wind resistance).

IC Role / Device Role / Timing Role: Primary motor controller executing LIN-commanded motion profiles, real-time current monitoring, and fault-safe shutdown.

Use Value: Integrated LIN transceiver and H-bridge driver reduce component count by 4 ICs vs discrete solution; +175°C rating allows direct mounting on wiper motor housing.

Use Scenario: Soft-start, anti-pinch detection, and programmable lift/drop timing for automotive door glass actuators.

IC Role / Device Role / Timing Role: LIN slave node managing motor direction, PWM duty cycle, and shunt-based current threshold detection for obstruction sensing.

Use Value: On-chip op-amp enables sub-100 ns current sampling latency - critical for reliable anti-pinch response within 100 ms safety window.

Roof Sunroof Actuator

Trunk/Tailgate Power Opener

Use Scenario: Bidirectional control of sunroof sliding and tilt mechanisms with end-stop detection and obstacle reaction.

IC Role / Device Role / Timing Role: Standalone LIN-controlled actuator MCU performing closed-loop position tracking using hall sensor inputs and PWM-driven H-bridge.

Use Value: 64 KB flash stores multiple motion profiles and calibration tables; VQFN-48-79 package fits compact sunroof ECU housing with minimal thermal derating.

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 (not H-bridge); no LIN transceiver; 32 KB flash, 4 KB RAM.	Targeted at BLDC fans/pumps; requires external LIN transceiver and voltage regulator for automotive use.	Select when controlling 3-phase motors and LIN is handled externally; not drop-in for TLE9867QXW20XUMA3's DC/H-bridge/LIN integration.
DRV3205-Q1	Standalone H-bridge gate driver (no MCU, no LIN, no op-amp); requires external microcontroller and transceiver.	Used in modular designs where MCU and driver are separated; lacks current sensing and communication integration.	Choose only when existing MCU platform already handles LIN and current sensing; adds ≥3 ICs vs TLE9867QXW20XUMA3's SoC approach.

Compared with STSPIN32F0B and DRV3205-Q1, the TLE9867QXW20XUMA3 uniquely combines MCU, LIN, H-bridge driver, and current-sense amplifier in one AEC-Q100 Grade 0 package - reducing bill-of-materials, board space, and validation effort for single-motor DC actuator nodes.

FAQ

What is the maximum ambient temperature for continuous operation of TLE9867QXW20XUMA3?

The device is qualified to AEC-Q100 Grade 0 with junction temperature range –40°C to +175°C. Ambient temperature depends on PCB layout and airflow, but with typical 2-layer board and 2 cm² copper pour, it supports 105°C ambient at full load. Thermal pad soldering and heatsinking are required for sustained +175°C Tj operation.

Does TLE9867QXW20XUMA3 support bootloader updates over LIN?

Yes - the device includes a ROM-based bootloader accessible via LIN using UDS (ISO 14229-1) diagnostic services. It supports flash reprogramming in-application (IAP) with checksum verification, write protection, and secure boot signature checking using embedded public-key infrastructure.

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

No - the op-amp is internally routed only to the shunt differential inputs (SHUNT_P/SHUNT_N) and configured for fixed gain (≥20 V/V) with rail-to-rail output. It lacks external feedback pins or programmable gain; voltage sensing must use the 10-bit ADC channels with appropriate external resistive dividers.

Is the charge pump in the H-bridge driver capable of sustaining 100% duty cycle on high-side MOSFETs?

Yes - the integrated charge pump supports continuous high-side gate drive up to 28 V VBAT, with automatic refresh during PWM dead-time and no external capacitor required. It maintains gate voltage ≥10 V for N-MOSFETs with VGS(th) ≤2.5 V across full temperature and voltage range.
