3-Phase Bridge Driver IC - Arm® Cortex® M3
Infineon`s 3-phase motor control solutions with CAN or LIN interface addressing BLDC motor applications
The MOTIX™ TLE987x and TLE989x families offer solutions for a wide range of smart 3-phase brushless DC motor control applications like auxiliary pumps and fans. They provide an unmatched level of integration and system cost to optimize the target application segments. In addition to this, they offer 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.
Moreover, TLE989x family with integrated CAN-FD interface is developed according to ISO 26262 providing ASIL B and security features.
- High system frequency (60 MHz) and dual flash (read-while-write)
- Smallest fully integrated motor control solution with CAN FD
- ISO 26262 compliance (ASIL B) and context segregation (layered access right management)
- Infineon’s patented Adaptive MOSFET Control (AMC) feature
- Premium design-in support with software, tools and services
The new TLE989x devices use a B6 bridge N-channel MOSFET driver, an Arm® Cortex® M3 microcontroller, and a CAN (FD) controller and transceiver supporting a communication speed of 2 Mbps. Customers benefit not only from fast and robust communication but also from the highest computing performance.
