TLE9879QXA20XUMA2

Application Specific Microcontrollers Overview

The TLE9879QXA20XUMA2 is an automotive-grade microcontroller with a BLDC MOSFET driver, part of the MOTIX™ family. It integrates a 32-bit ARM Cortex-M3 core operating up to 24 MHz with 128 kByte Flash and 6 kByte RAM. The device features a single power supply range of 5.5 V to 27 V (extended to 3 V–28 V) and includes a LIN 2.2 transceiver, charge pump for B6 bridge drivers, and high-speed operational amplifiers for shunt current sensing. It supports sensorless and sensor-based BLDC control in a VQFN-48 package.

Application Specific Microcontrollers Procurement Notes

Verify the ordering suffix XUMA2 corresponds to the specific tape-and-reel packaging configuration required for production. Confirm that the BF-step designation aligns with the intended design-in phase and that all electrical parameters meet the target automotive application requirements.

Application Specific Microcontrollers Selection Notes

Select this variant when a 24 MHz Cortex-M3 core and 128 kByte Flash are sufficient for the control algorithm. Ensure the system utilizes a single power supply within the 5.5 V to 27 V range. Verify that the integrated LIN transceiver meets the network communication needs without requiring external components.

Application Specific Microcontrollers Part Context

This component belongs to the Infineon TLE9879 series of embedded power SoCs designed for automotive motor control. It combines a 32-bit MCU with power stages, targeting low-to-mid power three-phase BLDC motors. The QXA20 variant specifically denotes the memory configuration and package type within the MOTIX™ portfolio.

Application Specific Microcontrollers Replacement Considerations

TLE9879QXA40XUMA2 offers higher clock frequency and memory capacity. TLE9879QXA20_15 and TLE9879QXA20_17 represent different design steps or qualification levels within the same functional family.
