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

The TLE987x family addresses a wide range of smart 3-Phase Brushless DC motor control applications like auxiliary pumps and fans.

It provides an unmatched level of integration and system cost to optimize the target application segments. In addition to this, it 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.

Applications

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 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.

32-bit core for complex software solutions with Direct Memory Access (DMA) Controller up to 14 channels ensure high performance for applications. 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
