TLE9867QXW20XUMA1

Overview

The Infineon TLE9867QXW20 is a MOTIX™ microcontroller system-on-chip designed for automotive actuator drives. It integrates a 32-bit Arm® Cortex®-M3 core operating up to 24 MHz with 64 KB flash and 6 KB RAM. The device features an integrated H-bridge MOSFET driver with charge pump, a LIN 2.2 transceiver, and a high-speed operational amplifier for shunt-based motor current sensing. Powered by a single supply of 5.5 V to 28 V, it supports an extended junction temperature range from -40°C to +175°C. Qualified under AEC-Q100/101 standards, the component utilizes a VQFN-48-29 package.

Feature Summary

• Integrated 32-bit Arm® Cortex®-M3 processor with 64 KB flash and 6 KB RAM
• Built-in H-bridge MOSFET driver with charge pump for direct motor control
• LIN 2.2 transceiver for automotive network communication
• High-speed operational amplifier for precise motor current sensing via shunt resistors

Applications

• Windshield wiper systems
• Auxiliary pumps and fans
• Window lift actuators
• Sunroof and tailgate drive modules

Procurement Notes

Verify the specific ordering suffix (e.g., XUMA1) against the manufacturer's datasheet table to confirm the exact package variant, as different suffixes correspond to distinct physical packages like VQFN-48-29 or VQFN-48-79. Ensure the design accounts for the moisture sensitivity level and reflow soldering profile requirements specified in the official documentation.

Selection Notes

Select this component for applications requiring a highly integrated solution that combines MCU logic, power stage driving, and LIN communication on a single die. The inclusion of a dedicated high-speed op-amp makes it suitable for designs relying on shunt-based current sensing rather than Hall-effect sensors. Confirm that the 24 MHz clock speed and memory size meet the firmware complexity requirements.

Part Context

This part belongs to the Infineon MOTIX™ family of embedded power ICs based on the Arm® Cortex®-M architecture. It is classified as a QM Family product intended for automotive use. The TLE9867 series provides a scalable platform for brushed DC motor control, offering varying levels of integration regarding flash size and peripheral interfaces within the same ecosystem.

Replacement Considerations

Check the manufacturer's product selection guide for alternative parts within the TLE986x or TLE987x families. Verify compatibility regarding pinout, package dimensions (VQFN-48), and electrical characteristics such as supply voltage range and thermal performance before substitution.
