Product details

Overview

TLE9867QXA40XUMA4 from Infineon Technologies is an automotive-qualified Arm® Cortex®-M3 microcontroller integrating a LIN 2.2 transceiver, H-bridge MOSFET driver with charge pump, and high-speed operational amplifier for shunt-based motor current sensing. It delivers 64 KB flash, 6 KB RAM, operates from 5.5 V to 28 V single supply, and supports junction temperatures from –40°C to +150°C - enabling direct integration in wiper, window lift, and tailgate actuator control.

For engineers reviewing the TLE9867QXA40XUMA4 datasheet, TLE9867QXA40XUMA4 pinout, TLE9867QXA40XUMA4 application, or TLE9867QXA40XUMA4 equivalent, this device serves as a system-on-chip solution for brushed DC motor control in AEC-Q100 qualified automotive body electronics where space, thermal resilience, and LIN communication are critical.

Technical Context

The TLE9867QXA40XUMA4 integrates a 32-bit Arm Cortex-M3 core with on-chip OSC and PLL for precise clock generation, supporting real-time motor control loops. Its power management unit provides regulated 5.0 V (VDDP) and 1.5 V (VDDC) rails from a wide 5.5–28 V input, eliminating external regulators in many designs.

The integrated H-bridge driver includes gate charge pump, overcurrent protection, and thermal shutdown, while the dedicated high-speed op-amp enables accurate bidirectional current sensing via low-value shunt resistors - all synchronized under MCU control without external signal conditioning.

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
STSPIN32F0B	Integrated 3-phase gate driver; no LIN transceiver; 32 KB flash; requires external LIN PHY.	Better suited for BLDC fans/pumps; lacks automotive LIN slave node capability.	Select when multi-phase motor control is required and LIN is handled externally or omitted.
TI DRV8876-Q1	Standalone H-bridge driver (no MCU); 65 V abs max; supports SPI diagnostics only - no embedded firmware.	Requires external microcontroller; suitable for high-voltage (>28 V) or high-current (>3.5 A) applications.	Select when higher voltage tolerance or discrete control architecture is preferred over SoC integration.

Compared with STSPIN32F0B and DRV8876-Q1, the TLE9867QXA40XUMA4 uniquely combines AEC-Q100 qualified MCU, LIN 2.2 PHY, and H-bridge driver in one VQFN-48 package - reducing system-level component count and validation effort for single-motor body electronics.

FAQ

What is the maximum continuous motor current supported by the TLE9867QXA40XUMA4?

The TLE9867QXA40XUMA4 does not drive motors directly but controls external N-channel MOSFETs via its H-bridge gate driver outputs (OUT_H/OUT_L). With appropriate MOSFET selection and PCB thermal design, it supports continuous motor currents up to 1.5 A per channel. Peak current capability depends on external FET R_DS(on), heatsinking, and duty cycle - validated in Infineon's reference design TLE9867-REFKIT.

Does the TLE9867QXA40XUMA4 include flash programming and debug interfaces?

Yes - it features SWD (Serial Wire Debug) interface accessible via dedicated TMS/TCK pins, supporting full read/write/erase of the 64 KB flash memory and real-time debugging of the Cortex-M3 core. Flash is also protected by write/erase lock bits and secure boot options configurable during production programming.

Can the on-die op-amp be used for purposes other than motor current sensing?

The op-amp is optimized for differential shunt voltage amplification (gain = 20 V/V, bandwidth = 10 MHz) and shares bias circuitry with the current-sense path. While its inputs are accessible via dedicated pins (CSN_P/CSN_N), Infineon documentation specifies no guaranteed performance for general-purpose use - calibration, offset, and noise characteristics are characterized only for motor current sensing applications.

Is the LIN transceiver compliant with LIN SAE J2602 physical layer requirements?

Yes - the integrated LIN transceiver meets SAE J2602-1 (2013) specifications for bus voltage range (–18 V to +40 V), dominant timeout, slew rate, and wake-up pulse detection. It supports LIN 2.2 protocol layers via firmware and includes automatic sync-break detection and checksum verification per LIN specification.
