Product details

Overview

TLE9867QXW20XUMA1 from Infineon is an automotive-grade 32-bit 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 a single 5.5–28 V supply, delivers 64 KB flash and 6 KB RAM, and supports extended junction temperature up to +175°C - designed for wiper, window lift, and auxiliary fan control in Grade 0 automotive systems.

For engineers reviewing the TLE9867QXW20XUMA1 datasheet, TLE9867QXW20XUMA1 pinout, TLE9867QXW20XUMA1 application, or TLE9867QXW20XUMA1 equivalent, this device offers integrated power stage control, on-chip clock generation (OSC + PLL), and AEC-Q100 qualified operation - critical for space-constrained, thermally demanding body electronics modules.

Technical Context

The TLE9867QXW20XUMA1 integrates system-level functions into a single die: its SCU-PM unit manages power sequencing and voltage regulation (VDDP = 5.0 V, VDDC = 1.5 V), while the SCU-DM provides clock generation with both low-precision RC and high-precision crystal/external-input oscillator modes. The embedded LIN transceiver complies fully with ISO 17987-2:2013 and supports wake-up via bus activity.

Its analog subsystem includes a dedicated high-speed operational amplifier optimized for real-time motor phase current measurement using low-value shunt resistors, coupled with ADC input routing and programmable gain. The H-bridge driver supports 100% duty cycle operation and features integrated charge pump, overcurrent protection, and thermal shutdown - all controlled directly by the Cortex-M3 core without external logic.

Key Specifications

Applications

Wiper Motor Control

Window Lift Actuator

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

IC Role / Device Role / Timing Role: Main controller executing PWM-driven H-bridge commutation, LIN communication with BCM, and analog current monitoring for stall detection.

Use Value: Integrated op-amp and LIN transceiver reduce component count by ≥4 devices; Grade 0 rating ensures reliability in hot dashboard environments.

Use Scenario: Anti-pinch window lift module with force feedback and soft-stop behavior.

IC Role / Device Role / Timing Role: Real-time motor current profiling via shunt + op-amp, closed-loop speed control using GPT12 timers, and LIN command parsing for master-slave coordination.

Use Value: 175°C junction rating enables mounting inside door modules without heatsinks; on-chip VDDP/VDDC regulators simplify power design.

Auxiliary Cooling Fan

Sunroof Drive System

Use Scenario: PWM-controlled radiator fan with temperature-based speed ramping and diagnostic logging.

IC Role / Device Role / Timing Role: Executes thermal lookup tables, drives H-bridge with adaptive dead-time, monitors current for blade obstruction, and reports status via LIN.

Use Value: Single-supply operation (5.5–28 V) eliminates need for separate 5 V rail; integrated watchdog (WDT1) and voltage monitors ensure fail-safe shutdown.

Use Scenario: Bidirectional sunroof glass movement with obstacle detection and smooth acceleration/deceleration profiles.

IC Role / Device Role / Timing Role: Coordinates dual H-bridge control, processes Hall sensor inputs for position tracking, and implements LIN-based calibration routines during service mode.

Use Value: CCU6 unit provides hardware-accelerated PWM generation with complementary outputs and fault blanking - critical for synchronized motor winding control.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLE9879QXW40	Higher integration: adds CAN FD controller, 128 KB flash, 12 KB RAM, and dual H-bridge drivers - larger die, higher cost, wider VBAT range (4.5–28 V).	Targeted at multi-actuator nodes (e.g., seat + mirror + sunroof) requiring CAN backbone connectivity and expanded memory.	Select when CAN FD communication, larger firmware footprint, or dual independent motor control is required - not drop-in compatible due to pinout and register map changes.
MC9S12VR64	Legacy 16-bit S12X core, no integrated LIN transceiver or H-bridge driver; requires external transceiver, gate drivers, and regulators.	Used in legacy wiper modules where redesign is constrained by existing PCB layout and toolchain dependencies.	Choose only for maintenance of legacy designs; lacks AEC-Q100 Grade 0 qualification and modern power efficiency.

Compared with TLE9867QXW20XUMA1, the TLE9879QXW40 offers CAN FD and greater memory but increases BOM cost and complexity, while the MC9S12VR64 requires ≥6 additional components and fails to meet current Grade 0 thermal requirements - making the TLE9867QXW20XUMA1 optimal for new single-motor LIN nodes.

FAQ

What is the maximum ambient temperature this device supports in a sealed enclosure?

The TLE9867QXW20XUMA1 is qualified for junction temperatures up to +175°C (AEC-Q100 Grade 0). In a sealed enclosure with no forced airflow, maximum ambient depends on PCB copper area, thermal pad soldering quality, and power dissipation. With 2 oz. copper and full thermal pad reflow, ambient can reach +105°C at 1.2 W total dissipation - verified in Infineon's thermal simulation report AN478.

Does the integrated LIN transceiver support LIN Sleep/Wake functionality?

Yes. The LIN transceiver supports full ISO 17987-2:2013 sleep mode: it draws <15 µA in standby, detects dominant bus timeouts or sync field pulses to wake the MCU, and asserts WAKE_N signal to the SCU-PM. Wake-up latency is ≤100 µs from bus activity detection to CPU execution resume.

Can the on-chip op-amp be used for motor phase voltage sensing instead of current sensing?

No. The op-amp is internally routed only to ADC0 and configured exclusively for differential shunt voltage amplification (gain = 10 V/V typical). Its input common-mode range is limited to 0–VDDP, and it lacks rail-to-rail input capability required for direct phase voltage measurement across full battery range.

Is there hardware support for Field-Oriented Control (FOC) of BLDC motors?

Yes. The CCU6 unit provides hardware-accelerated center-aligned PWM with dead-time insertion, complementary output pairs, and fault blanking - essential for FOC three-phase gate driving. Combined with the high-speed op-amp and 12-bit ADC (1 µs conversion), it enables real-time current sampling per PWM period at up to 20 kHz switching frequency.
