Product details

Overview

TLE9871QXA20XUMA2 from Infineon Technologies is an automotive-qualified Arm® Cortex®-M3 microcontroller integrating a 3-phase BLDC MOSFET gate driver, 36 KB on-chip flash, 3 KB RAM, and a high-speed operational amplifier for shunt-based motor current sensing. It operates from a single 5.5 V to 28 V supply and supports junction temperatures from –40°C to +150°C, targeting wiper, window lift, and auxiliary fan control in body electronics.

For engineers reviewing the TLE9871QXA20XUMA2 datasheet, TLE9871QXA20XUMA2 pinout, TLE9871QXA20XUMA2 application, or TLE9871QXA20XUMA2 equivalent, this device delivers integrated motor control with embedded PWM timing, on-die clock generation (OSC + PLL), and AEC-Q100 qualified reliability for under-hood and cabin-mounted automotive actuators.

Technical Context

The TLE9871QXA20XUMA2 integrates a dedicated high-voltage PWM interface supporting three half-bridge outputs with programmable dead-time insertion and fault protection. Its SCU-PM subsystem manages power sequencing, including dual voltage regulators (5.0 V VDDP and 1.5 V VDDC) and external 5.0 V regulator support (VDDEXT).

Motor control execution relies on the CCU6 capture/compare unit for precise 3-phase commutation timing, GPT12 timers for auxiliary timing tasks, and UART1/UART2 for diagnostics and host communication. The integrated op-amp enables real-time current feedback without external signal conditioning circuitry.

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 core, 32 KB flash, no integrated op-amp; requires external current sense amplifier.	Limited to lower ambient temps (–40°C to +125°C); lacks AEC-Q100 Grade 1 validation for under-hood use.	Preferred for cost-sensitive non-critical cabin fans where external sensing is acceptable.
DRV3205-Q1	Standalone 3-phase gate driver (no MCU); requires external microcontroller for commutation logic and timing.	Enables flexible MCU selection but increases PCB area and interconnect complexity vs. integrated solution.	Chosen when existing platform uses different MCU architecture or requires higher voltage/current ratings (>60 V / >30 A).

Compared with STSPIN32F0B and DRV3205-Q1, the TLE9871QXA20XUMA2 uniquely combines AEC-Q100 Grade 1 qualification, integrated current-sense op-amp, and single-supply operation - reducing total component count and validation effort for new automotive body actuator designs.

FAQ

What is the maximum PWM frequency supported by the TLE9871QXA20XUMA2?

The high-voltage PWM interface supports up to 100 kHz switching frequency with programmable dead time down to 50 ns. This is confirmed in Section 20.1 of the datasheet Rev. 2.2 and enables efficient operation of low-inductance BLDC motors used in automotive actuators while maintaining thermal safety margins.

Does the TLE9871QXA20XUMA2 include hardware-based functional safety features?

Yes - it integrates a watchdog timer (WDT1), memory protection unit (MPU), and lock-step capable peripherals. While not ASIL-B certified out-of-box, its architecture supports ISO 26262-compliant software implementation per Infineon's MOTIX™ safety manual (AN50123), including error-correcting code for flash and parity for RAM.

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

No - the op-amp is specifically designed and characterized for differential shunt current sensing with fixed gain and input common-mode range centered at VDDP/2. Its inputs are internally biased and lack rail-to-rail common-mode capability required for generic voltage monitoring applications.

Is the VQFN-48-31 package lead-free and RoHS compliant?

Yes - the TLE9871QXA20XUMA2 uses lead-free matte tin plating per JEDEC J-STD-020 and complies with EU RoHS Directive 2011/65/EU and China RoHS II. The package marking "TLE9871QXA20" and date code are laser-etched on the top surface.
