Product details

Overview

TLE9871QXA20XUMA1 from Infineon Technologies is an automotive-qualified 32-bit Arm® Cortex®-M3 microcontroller integrating a 3-phase BLDC MOSFET gate driver, high-speed op-amp for shunt-based current sensing, on-chip 5.0 V and 1.5 V regulators, and PWM interface - delivering full motor control in a single chip for 12 V/24 V systems operating from −40°C to +150°C junction temperature.

For engineers reviewing the TLE9871QXA20XUMA1 datasheet, TLE9871QXA20XUMA1 pinout, TLE9871QXA20XUMA1 application, or TLE9871QXA20XUMA1 equivalent, this device supports sensorless BLDC commutation, meets AEC-Q100 Grade 0 requirements, and integrates power management, timing, and analog signal conditioning for compact wiper, fan, and window lift subsystems.

Technical Context

The TLE9871QXA20XUMA1 implements a tightly coupled system-on-chip architecture where the Cortex-M3 core (72 MHz max) directly controls six high-side/low-side gate drivers via CCU6 PWM units with dead-time insertion and fault protection. Its integrated charge pump enables full N-channel MOSFET driving from a single 5.5–28 V supply.

Analog subsystem includes a dedicated high-speed operational amplifier (gain-bandwidth product ≥ 10 MHz) optimized for real-time motor phase current sensing across shunt resistors, plus 10-bit ADC with hardware-triggered sampling synchronized to PWM edges for precise current loop execution.

Key Specifications

Applications

Wiper Motor Control

Fan Speed Regulation

Use Scenario: Variable-speed windshield wiper system with rain-sensing feedback and soft-start ramping.

IC Role / Device Role / Timing Role: Primary motor controller executing 6-step commutation, reading Hall sensor or back-EMF, and managing LIN communication to body controller.

Use Value: Integrated op-amp and ADC enable precise current monitoring during stall detection; single-supply operation reduces wiring complexity in front-end harnesses.

Use Scenario: HVAC blower fan with variable airflow demand and thermal derating based on ambient temperature.

IC Role / Device Role / Timing Role: Standalone BLDC controller handling speed regulation, overtemperature shutdown, and CAN/LIN diagnostics reporting.

Use Value: On-chip 28 V tolerant supply interface allows direct battery connection; 150°C rating permits mounting inside fan housing for compact integration.

Window Lift Actuator

Sunroof Drive Module

Use Scenario: Anti-pinch window lift with force detection via motor current profiling and position tracking.

IC Role / Device Role / Timing Role: Real-time current-loop controller using shunt sensing and PWM modulation to detect mechanical obstruction within 5 ms.

Use Value: Hardware-triggered ADC sampling synchronized to PWM ensures sub-µs timing accuracy for force calculation; embedded watchdog guarantees fail-safe stop on fault.

Use Scenario: Dual-direction sunroof actuation with smooth acceleration/deceleration and obstacle detection.

IC Role / Device Role / Timing Role: Dedicated motor controller managing bidirectional 3-phase drive, position estimation, and LIN command parsing.

Use Value: Integrated charge pump and gate drivers reduce external component count by 6+ discrete parts; VQFN-48 thermal pad enables efficient heat dissipation in confined module space.

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	Integrated 3-phase gate driver + Cortex-M0 core; 24 KB flash; no on-chip op-amp or dedicated current-sense path.	Limited to lower-power fans/pumps (<100 W); requires external op-amp for shunt sensing.	Select when cost sensitivity outweighs need for integrated analog sensing and higher temp rating.
DRV3205-Q1	Standalone 3-phase gate driver (no MCU); requires external microcontroller and op-amp/ADC.	Used in modular designs where MCU and driver are separated for flexibility or thermal isolation.	Select when existing MCU platform must be retained or when higher drive strength (>1.5 A peak) is required.

Compared with STSPIN32F0B and DRV3205-Q1, the TLE9871QXA20XUMA1 uniquely combines AEC-Q100 Grade 0 operation, integrated high-speed current-sense op-amp, and single-supply 28 V tolerance - enabling smaller, more robust motor modules for demanding automotive body applications.

FAQ

What is the maximum junction temperature rating for TLE9871QXA20XUMA1?

The TLE9871QXA20XUMA1 is qualified to AEC-Q100 Grade 0 with a maximum junction temperature of +150°C. This rating is validated through accelerated life testing and thermal characterization per JEDEC standards, enabling direct mounting on motor housings or in engine bay environments without derating.

Does TLE9871QXA20XUMA1 require an external crystal oscillator?

No - the device includes an on-chip high-precision oscillator (OSC_HP) supporting both external crystal (1–20 MHz) and external clock input modes, plus a PLL for generating the 72 MHz core clock. An external crystal is optional and only needed if highest frequency stability is required.

Can TLE9871QXA20XUMA1 drive N-channel MOSFETs exclusively?

Yes - its integrated charge pump generates boosted gate drive voltage for high-side N-channel MOSFETs, eliminating the need for P-channel devices or external bootstrap circuitry. The driver supports 5.5–28 V supply and delivers ≥1 A peak sink/source current per channel.

Is there hardware support for sensorless BLDC commutation?

Yes - the CCU6 PWM unit provides hardware-accelerated 6-step commutation with programmable dead time, while the ADC and op-amp enable real-time back-EMF zero-crossing detection. Firmware libraries for sensorless FOC and trapezoidal control are provided in Infineon's MOTIX™ SDK.
