Overview

The TLE9879QXA40XUMA2 is part of the Infineon MOTIX family, integrating a 32-bit Arm Cortex-M3 core with a dedicated 3-phase MOSFET gate driver. This SoC is designed for brushless DC (BLDC) motor control, combining a microcontroller, LIN transceiver, and analog peripherals into a single VQFN-48 package. It operates over a wide voltage range of 5.5V to 28V and is qualified for extreme automotive temperatures up to 150 degrees Celsius.

Why Choose This Part

This device reduces PCB area by integrating the MOSFET gate driver, charge pump, and a high-speed operational amplifier for shunt-based current sensing. The AEC-Q100 qualification and support for temperatures up to 150 degrees Celsius make it suitable for under-the-hood engine compartment applications. System-level reliability is enhanced through built-in short-circuit, overtemperature, and undervoltage protection.

Applications

Automotive HVAC Blowers
Controlling cabin climate control fans with precise PWM and integrated LIN communication for vehicle networking.
Electric Water and Oil Pumps
Driving high-efficiency brushless motors in powertrain cooling and lubrication systems.
Windshield Wipers
Managing complex wiper motor profiles with integrated current sensing and stall detection.
Fuel Pumps
Providing reliable motor control for fuel delivery systems with integrated diagnostic and protection features.

Getting Started

Engineers can evaluate this SoC using the TLE9879 EvalKit or the low-cost TLE9879 Shield for Arduino. Development is supported by Infineon Config Wizard and Keil MDK, which allow for rapid configuration of the motor control peripherals and bridge driver. Proper thermal management of the VQFN-48 package is essential, as the integrated gate drivers generate heat during high-frequency switching.
