Infineon Embedded Power IC TLE987x for BLDC Motor Control
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 is a 3rd Generation Embedded Power IC based on ARM® Cortex™-M3 core and addresses a wide range of smart 3-Phase Brushless DC motor control applications.
The TLE987x features
- Widely accepted 32-bit CPU core
- High integration:
- MCU
- LDO
- LIN 2.2 transceiver
- MOSFET Gate driver
- Current sense amplifier
- Current programmable NFET Gate with charge pump and current slope control
- Wide operating range from 5.4V to 28V, MCU operates downto 3.0V
Benefits
- Computing performance enables Field Oriented Control (FOC)
- System cost optimized solution with low BOM for compact designs
- Gate corrent slope control optimizes the system EMC behavior for a wide range of MOSFETs
- Sensorless FOC with single shunt current measurement
Applications
- Generic 3-phase motor control
- HVAC fans
- Engine cooling fans
- Water pump
- Fuel pump
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.
