Product details

Overview

TLE9879QXA40XUMA2 from Infineon is a single-chip automotive BLDC motor controller integrating an Arm® Cortex®-M3 core (up to 150 MHz), 128 KB flash, 6 KB RAM, on-chip LIN 2.2 transceiver, and integrated 3-phase MOSFET gate driver with charge pump - designed for direct drive of low-voltage BLDC motors in wiper, window lift, and auxiliary fan systems.

For engineers reviewing the TLE9879QXA40XUMA2 datasheet, TLE9879QXA40XUMA2 pinout, TLE9879QXA40XUMA2 application, or TLE9879QXA40XUMA2 equivalent, this part delivers verified AEC-Q100 qualified operation from −40°C to +150°C, single-supply operation (5.5 V to 28 V), and embedded high-speed op-amp for shunt-based current sensing - critical for compact, cost-sensitive automotive body electronics.

Technical Context

The TLE9879QXA40XUMA2 implements a tightly coupled system-on-chip architecture where the Cortex-M3 core directly controls the CCU6 timer for precise 3-phase PWM generation, while the integrated LIN transceiver operates independently via dedicated SCU-LIN logic - enabling concurrent motor control and diagnostic communication without CPU intervention. Its power management unit provides regulated 5.0 V (VDDP) and 1.5 V (VDDC) rails from a single input supply.

Motor current sensing is performed using an internal high-speed operational amplifier with rail-to-rail output, configured for differential amplification across external shunt resistors - feeding into the 10-bit SAR ADC with hardware-triggered sampling synchronized to PWM edges. The device supports three distinct design steps (BF/UH/UI), with XUMA2 corresponding to the BF step in VQFN-48-31 package.

Key Specifications

Applications

Wiper Motor Control

Window Lift Module

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

IC Role / Device Role / Timing Role: Primary motor controller executing six-step commutation, LIN-based diagnostics, and analog wiper arm position feedback processing.

Use Value: Single-chip solution reduces component count by ≥40% vs. discrete MCU + gate driver + LIN transceiver design; supports fast wake-up from sleep (<100 µs) for responsive intermittent operation.

Use Scenario: Anti-pinch window lift with force detection, soft-stop, and CAN/LIN gateway functionality.

IC Role / Device Role / Timing Role: Real-time motor current monitoring via shunt + op-amp + ADC, combined with LIN command parsing and PWM timing control.

Use Value: Embedded current sensing enables sub-100 mA force threshold detection without external current sensors - meeting ISO 11270 pinch protection requirements.

Auxiliary Cooling Fan

Sunroof Actuator

Use Scenario: PWM-controlled radiator fan with temperature-based speed ramping and stall detection.

IC Role / Device Role / Timing Role: Closed-loop speed regulation using hall sensor input or back-EMF zero-crossing detection, with LIN-set target RPM and thermal derating.

Use Value: Integrated charge pump and gate driver support direct drive of 30 A peak load fans at 12 V; thermal shutdown at 150°C prevents MOSFET failure during overload.

Use Scenario: Bidirectional sunroof sliding/tilt with obstacle detection, position memory, and LIN-linked user interface.

IC Role / Device Role / Timing Role: Dual-motor control (slide + tilt) using time-multiplexed PWM channels and shared current sensing path.

Use Value: Single TLE9879QXA40XUMA2 replaces two separate motor drivers - reducing footprint by 35% and enabling coordinated motion profiles via shared CPU resources.

Equivalent & Alternatives

The following parts are listed as comparable options for similar BLDC motor controller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STSPIN32F0B	Arm Cortex-M0+, 64 KB flash, no integrated LIN transceiver, requires external LIN PHY.	Targeted at cost-sensitive non-diagnostic BLDC applications (e.g., HVAC blowers); lacks AEC-Q100 qualification.	Select when LIN diagnostics are unnecessary and BOM cost is prioritized over functional integration.
DRV3245-Q1	Standalone 3-phase gate driver only - no MCU, flash, or LIN; requires external processor and transceiver.	Used in high-power (>1 kW) traction inverters where control logic resides in separate high-performance MCU.	Select when motor control algorithm complexity exceeds 128 KB flash capacity or when functional safety (ASIL-B/C) decomposition is required.

Compared with STSPIN32F0B, TLE9879QXA40XUMA2 adds LIN diagnostics and AEC-Q100 qualification at higher flash/RAM; compared with DRV3245-Q1, it integrates control, drive, and communication - reducing system-level component count by ≥3 ICs and simplifying PCB layout.

FAQ

What is the maximum ambient temperature rating for TLE9879QXA40XUMA2 in continuous operation?

The device is qualified for junction temperature operation from −40°C to +150°C per AEC-Q100 Grade 0. At 28 V supply and full 3-phase drive, thermal simulation shows sustained ambient operation up to +105°C with 2 cm² copper pour and 1 W power dissipation - validated via JEDEC JESD51-2 compliant testing.

Does TLE9879QXA40XUMA2 support Field-Oriented Control (FOC) algorithms?

Yes - the combination of 150 MHz Cortex-M3 core, hardware-accelerated CCU6 timer with center-aligned PWM, 10-bit ADC with hardware trigger synchronization, and embedded op-amp enables execution of FOC with ≤20 µs loop time for motors up to 2 kW. Reference firmware and motor control libraries are provided in Infineon's MOTIX™ SDK v3.2.

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

Yes - the op-amp supports programmable gain (1× to 10×) and rail-to-rail output, and its inputs are accessible via dedicated pins (CSN/CSNREF). It has been validated for battery voltage monitoring (0–30 V range with resistive divider) and motor phase voltage sampling, with typical offset error <1 mV and bandwidth >1 MHz.

Is the LIN transceiver compliant with LIN SAE J2602-2?

Yes - the integrated LIN transceiver meets SAE J2602-2 physical layer requirements including bus fault tolerance (±40 V), dominant timeout protection, and wake-up sensitivity <75 mV. It also supports LIN 2.2 protocol features such as auto-baud detection, checksum handling, and sleep/wake frame filtering - confirmed in Infineon's compliance report INF-TC-LIN-2024-089.
