Product details

Overview

TLE9861QXA20XUMA1 from Infineon is an automotive-qualified Arm® Cortex®-M3 microcontroller integrating a high-voltage H-bridge MOSFET driver, 36 KB flash, 3 KB RAM, and a dedicated high-speed op-amp 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. Designed for brushed DC motor control in wiper, window lift, and tailgate actuation systems.

For engineers reviewing the TLE9861QXA20XUMA1 datasheet, TLE9861QXA20XUMA1 pinout, TLE9861QXA20XUMA1 application, or TLE9861QXA20XUMA1 equivalent, this device delivers integrated power stage control, on-chip clock generation via OSC/PLL, and AEC-Q100-qualified reliability for under-hood and body electronics.

Technical Context

The TLE9861QXA20XUMA1 integrates a 32-bit Arm Cortex-M3 core with tightly coupled peripherals including GPT12 timers, CCU6 capture/compare unit, UART1/UART2, and a high-voltage PWM interface supporting up to 28 V drain-source voltage. Its SCU-PM subsystem manages gate driving with integrated charge pump and overcurrent protection logic.

Power management includes dual regulated supplies: 5.0 V (VDDP) for digital logic and 1.5 V (VDDC) for the core, plus support for external 5.0 V regulation (VDDEXT). The high-speed operational amplifier enables real-time current feedback with <1 µs propagation delay and rail-to-rail output swing.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLE9872QXA40	Higher flash (128 KB), larger RAM (12 KB), adds CAN FD interface and enhanced watchdog features.	Targeted at more complex body control modules requiring communication and multi-motor coordination.	Select when CAN bus integration or future firmware expansion headroom is required.
MC9S12VR64	Legacy S12X core, no integrated H-bridge driver, requires external gate drivers and op-amps.	Used in legacy wiper systems where redesign is constrained by existing hardware layout.	Choose only for drop-in replacement in legacy platforms with minimal BOM change tolerance.

Compared with TLE9861QXA20XUMA1, the TLE9872QXA40 offers greater compute and communication capability at higher cost and complexity, while the MC9S12VR64 lacks integrated power stage control - increasing design effort and component count for new implementations.

FAQ

What is the maximum operating voltage for the H-bridge outputs?

The TLE9861QXA20XUMA1 H-bridge outputs support up to 28 V drain-source voltage, matching standard automotive battery rails. This rating applies under continuous operation within the specified junction temperature range (−40°C to +150°C) and with proper PCB thermal design for the VQFN-48-31 package's exposed pad.

Does the device include a hardware watchdog timer?

Yes, it includes a dedicated WDT1 module with windowed operation, independent clock source, and reset generation on timeout or illegal access. The watchdog can be configured for timeout periods from 1 ms to 2.1 s and supports early warning interrupts before reset assertion.

Can the integrated op-amp drive an external ADC directly?

Yes, the CSOUT pin provides a rail-to-rail analog output with 10 mA drive capability and <1 µs propagation delay, compatible with most automotive-grade SAR and delta-sigma ADCs. No external buffer is required for sampling rates up to 1 MSPS.

Is the flash memory field-programmable via standard interfaces?

Yes, the 36 KB flash supports in-system programming via UART bootloader (UART1) using Infineon's DAPLink-compatible protocol. It also supports SWD debugging and programming through the JTAG/SWD interface with standard tools like iSYSTEM winIDEA or Segger J-Link.
