TLE9869QXA20XUMA1

Overview

The Infineon TLE9869QXA20 is a 32-bit microcontroller featuring an Arm Cortex-M3 core and an integrated H-bridge MOSFET driver. It includes 128 KB flash, 6 KB RAM, and a LIN 2.2 transceiver. The device operates on a single supply voltage ranging from 5.5 V to 28 V and supports junction temperatures from -40°C to +150°C. Key peripherals include a high-speed operational amplifier for current sensing, multiple timers, ADCs, and synchronous serial interfaces.

Feature Summary

• Integrated 32-bit Arm Cortex-M3 core with up to 24 MHz clock frequency
• Built-in H-bridge MOSFET driver with charge pump for motor control
• On-chip LIN 2.2 transceiver for automotive communication
• High-speed operational amplifier for shunt-based motor current sensing

Applications

• Windshield wiper systems
• Auxiliary pumps and fans
• Window lift actuators
• Sunroof drives
• Tailgate actuators

Procurement Notes

Verify the specific ordering suffix (e.g., XUMA2, XUMA3, or XUMA4) against the required package type (VQFN-48-31 or VQFN-48-79). Confirm that the requested part number matches the exact design step (BF, UH, or UI) specified in the project documentation to ensure correct marking and pinout compatibility.

Selection Notes

Select this component for applications requiring a highly integrated solution for brushed DC motor control. Ensure the system design accommodates the 5.5 V to 28 V supply range and utilizes the internal LIN transceiver if bus communication is required. Verify thermal management requirements given the 150°C maximum junction temperature rating.

Part Context

This part belongs to the MOTIX family of automotive microcontrollers designed for motor control applications. It integrates power stages and communication interfaces to reduce system complexity compared to discrete solutions.

Replacement Considerations

Direct replacements within the same product line include TLE9869QXA20XUMA2 (BF step), TLE9869QXA20XUMA3 (UH step), and TLE9869QXA20XUMA4 (UI step). These variants differ primarily in package marking and manufacturing step.
