3-Phase Bridge Driver IC with Integrated Arm® Cortex® M3

Overview

Infineon´s 3 Phase Bridge Driver ICs enable the implementation of advanced motor control algorithms

Infineon has combined its wealth of experience in motor control drivers for automotive applications with all the benefits of an industry-standard core. The unique result, our 3rd Generation Embedded Power IC based on Arm® Cortex®-M cores, addresses a wide range of smart 3-Phase Brushless DC motor control applications like, fuel pumps, HVAC fans, engine cooling fans, electrical water pumps.

Produced on Infineon’s first-in-industry automotive qualified 130nm Smart Power technology, the Infineon Embedded Power System-on-Chip solutions offer an unmatched level integration and system cost to performance to optimization for the target application segments.

The TLE987x family offers scalability in terms of Flash memory sizes and MCU system clock frequency supporting a wide range of motor control algorithms, either sensor-based or sensor-less. It uses the same MCU and peripherals as the TLE986x family, 2-Phase driver, enabling design synergies between DC and BLDC motor control applications.

The new Infineon Embedded Power IC is supported by a complete development tool chain provided by Infineon and third party vendors. The tool chain includes compiler, debugger, evaluation board, LIN low level driver and configuration tool as well as example software code for Motor Control.

BLDC motors are most suitable for applications demanding long-term continuous mission, steady operation and variable speed. Consequently, reliability, durability and accurate motion control have become of substantial importance for the functioning of body applications. With the impact of reliability and durability, the need for maintenance is less for BLDC motors. BLDC motor control applications enable high RPM with high dynamic and agility.

Our 3-Phase Bridge Driver with Integrated Arm® Cortex® M3 product family fits perfectly with these requirements. We offer single-chip system ICs which improve module reliability, and platform solutions for a variety of applications with optimized size and weight. Additionally, our solutions provide high reliability and increased lifetime. With the factors of simplified EMC design and a standard microcontroller core, the Arm® Cortex® M3, you will find the best fit.

Key benefits:

  • High reliability
  • Increased lifetime
  • Durability
  • High dynamics/agility
