Product details

Overview

TLE9861QXA20XUMA2 from Infineon Technologies is a 32-bit Arm® Cortex®-M3 automotive microcontroller integrating an H-bridge MOSFET driver, high-speed op-amp for shunt-based motor current sensing, on-chip OSC/PLL clock generation, 36 KB flash, and 3 KB RAM. It operates from a single 5.5 V to 28 V supply and supports junction temperatures from −40°C to +150°C. Designed for body electronics motor control, it enables compact, cost-optimized solutions in wiper, window lift, and auxiliary pump systems.

For engineers reviewing the TLE9861QXA20XUMA2 datasheet, TLE9861QXA20XUMA2 pinout, TLE9861QXA20XUMA2 application, or TLE9861QXA20XUMA2 equivalent, this device delivers integrated power-stage control, real-time current feedback, and AEC-Q100-qualified reliability for 12 V automotive subsystems without external gate drivers or precision amplifiers.

Technical Context

The TLE9861QXA20XUMA2 integrates a dedicated high-voltage PWM interface with programmable dead-time control and fault monitoring, directly driving external N-channel MOSFETs in half-bridge or H-bridge configurations. Its embedded SCU-PM unit manages power sequencing, voltage regulation (VDDP = 5.0 V, VDDC = 1.5 V), and thermal supervision.

It features a GPT12 timer block supporting capture/compare, PWM generation, and quadrature decoding, alongside CCU6 for advanced motor control waveforms. The high-speed op-amp (gain-bandwidth product >1 MHz) is internally connected to ADC inputs for precise shunt-resistor current measurement with <1 µs propagation delay.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STSPIN32F0B	Integrated 3-phase gate driver + M0+ core; no embedded op-amp; requires external current sense amplifier.	Targeted at BLDC fans/pumps; lacks AEC-Q100 Grade 0 rating and single-supply operation above 18 V.	Prefer when 3-phase commutation is mandatory and cost-per-watt is prioritized over design simplicity.
DRV3205-Q1	Standalone H-bridge gate driver (no MCU); requires external microcontroller and op-amp.	Used in high-power (>100 W) actuators where separation of control and power stages improves thermal management.	Choose when functional safety decomposition (ASIL-B decomposition) mandates physical separation of MCU and driver.

Compared with STSPIN32F0B and DRV3205-Q1, the TLE9861QXA20XUMA2 uniquely combines AEC-Q100 Grade 0 qualification, single-supply operation up to 28 V, and integrated current-sense signal conditioning-reducing total component count by ≥6 parts while maintaining ASIL-B ready software architecture.

FAQ

Does TLE9861QXA20XUMA2 include flash programming capability via UART?

Yes. The device supports UART-based bootloader programming using Infineon's DAVE™ IDE and standard LIN/UART physical layer. Firmware updates can be performed in-system without JTAG debugger, leveraging the built-in ROM bootloader and CRC-verified flash write routines.

What is the maximum continuous output current supported by the integrated gate driver?

The TLE9861QXA20XUMA2 does not drive load current directly; its gate driver outputs (OUT_Hx/OUT_Lx) source/sink up to 250 mA peak to switch external N-channel MOSFETs. Sustained motor current depends on selected external FETs, heatsinking, and PCB layout-validated reference designs achieve 10 A RMS with appropriate MOSFET selection.

Is the high-speed op-amp internally connected to the ADC?

Yes. The op-amp output is routed directly to ADC0 and ADC1 inputs via dedicated analog bus. This path bypasses GPIO multiplexing and includes programmable gain (1×, 5×, 10×, 20×) and offset calibration-enabling calibrated current measurement with ≤1 LSB INL error across temperature.

How is functional safety addressed in TLE9861QXA20XUMA2?

The device includes dual watchdog timers (WDT1 and WDT2), lockstep-capable memory protection unit (MPU), ECC on flash, and voltage/temperature monitors with configurable thresholds. It supports ASIL-B decomposition per ISO 26262 when combined with certified software libraries and external monitoring circuits.
