Infineon公司的TLE9879是集成了LIN 2.2与SAEJ2602兼容的LIN收发器和BLDC MOSFET驱动器微控制器,采用标准的ARM® Cortex™ M3内核,包括了六个全集成的NFET驱动器,适合通过外接六个功率NFET来驱动3相马达,主要用于汽车的燃料泵,HVAC,引擎冷却风扇,水泵和BLDC蚌与风扇.本文介绍了TLE9879主要特性,框图,BLDC马达驱动电路和材料清单,以及评估板TLE9879 EVALKIT,电路图和PCB设计文件图.

Microcontroller with LIN and BLDC MOSFET Driver for Automotive Applications

The TLE9879QXA20 is part of the TLE987x product family. The TLE9879QXA20 is a single chip 3-Phase motor driver that integrates the industry standard ARM® Cortex™ M3 core, enabling the implementation of advanced motor control algorithms such as field-oriented control. It includes six fully integrated NFET drivers optimized to drive a 3-Phase motor via six external power NFETs, a charge pump enabling low voltage operation and programmable current along with current slope control for optimized EMC behavior. Its peripheral set includes a current sensor, a successive approximation ADC synchronized with the capture and compare unit for PWM control and 16-bit timers. A LIN transceiver is also integrated to enable communication to the device along with a number of general purpose I/Os. It includes an on-chip linear voltage regulator to supply ext..
