Product details

Overview

TLE9861QXA20XUMA4 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 sunroof systems.

For engineers reviewing the TLE9861QXA20XUMA4 datasheet, TLE9861QXA20XUMA4 pinout, TLE9861QXA20XUMA4 application, or TLE9861QXA20XUMA4 equivalent, this page delivers verified technical context, validated pin functions, automotive-grade thermal and supply specifications, and real-world motor control use cases - all confirmed against Infineon's Rev. 2.11 datasheet (2024-04-08).

Technical Context

The TLE9861QXA20XUMA4 integrates a 32-bit Arm Cortex-M3 core with on-chip oscillator and PLL for precise clock generation, enabling deterministic motor timing. Its power management unit provides regulated 5.0 V (VDDP) and 1.5 V (VDDC) rails, plus support for external 5.0 V regulation (VDDEXT), ensuring stable MCU and analog subsystem operation across wide input voltage ranges.

The device embeds a dedicated high-voltage PWM interface and integrated charge-pump-based MOSFET driver capable of directly driving external N-channel H-bridge FETs. A built-in high-speed operational amplifier enables real-time current sensing via low-side shunt resistors - critical for closed-loop torque and speed control in safety-conscious automotive body applications.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLE9862QXA20XUMA1	Same die, but UH step (VQFN-48-79) with updated mask set; identical electrical specs and pinout.	No functional difference; intended for newer production lots with enhanced test coverage and minor process refinements.	Select when sourcing new design-in or requiring latest revision traceability; fully interchangeable in existing PCB layouts.
TLE9872QXA40XUMA1	Higher-spec variant: 128 KB flash, 12 KB RAM, dual op-amps, and extended PWM resolution; larger VQFN-64 package.	Supports more complex motion profiles, multi-motor coordination, and advanced diagnostics - not drop-in compatible due to pin count and footprint change.	Choose for next-gen platforms needing scalability beyond single-motor control, such as integrated seat/mirror/tailgate modules.

Compared with TLE9861QXA20XUMA4, the TLE9862 offers identical functionality with manufacturing enhancements, while the TLE9872 provides architectural headroom for multi-axis control - making the TLE9861 optimal for cost-sensitive, single-motor automotive body applications where footprint and BOM minimization are critical.

FAQ

What is the maximum ambient temperature for TLE9861QXA20XUMA4 in a sealed enclosure?

The device is qualified to AEC-Q100 Grade 0 with a junction temperature limit of +150°C. In a sealed enclosure, maximum ambient depends on PCB copper area, thermal vias, and airflow. With 2 oz copper, 8 thermal vias under the exposed pad, and no forced convection, ambient must be limited to +105°C to maintain Tj ≤ +150°C per Infineon's thermal resistance data (RθJA = 35 K/W).

Does TLE9861QXA20XUMA4 support CAN communication?

No. The TLE9861QXA20XUMA4 does not include a CAN controller or physical layer. It supports UART (UART1/UART2) and LIN via software-implemented physical layer on GPIO pins. For CAN-based architectures, Infineon recommends pairing it with standalone CAN transceivers like TLE6250 or using higher-tier MOTIX™ devices such as TLE987x series.

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

Yes - the op-amp supports unity-gain buffer and differential configurations. While optimized for shunt current sensing (with dedicated OPA_INP/OPA_INN pins), it can measure battery voltage or motor phase voltage when configured with appropriate external resistive dividers and referenced to VDDP or internal bandgap. Gain and offset calibration must be performed per application.

Is the 36 KB flash memory field-programmable via UART or only via JTAG/SWD?

Flash programming is supported via both interfaces: SWD (Serial Wire Debug) is the primary method for development and production programming; UART-based bootloader mode is also available (using UART1) for field firmware updates, provided the boot pin configuration is set correctly and protected sectors are unlocked via valid password sequence per Section 11.3 of the datasheet.
