[原创] Infineon TLE9845QX系列汽车马达控制方案

Infineon公司的TLE9845QX系列产品是集成了32位ARM® Cortex® M0内核的继电器驱动芯片,MCU工作频率高达40MHz.器件在单个芯片上集成了通过继电器或PN MOSFET半桥来检测,控制和启动电机所需的所有功能,包括48KB闪存,4KB EEPROM,768B 100TP存储器,4KB RAM以及引导ROM,具有高集成度和高性价比.主要用在汽车的电机控制应用如车窗升降器,雨刮,汽车天窗,风扇和风机等.本文介绍了TLE9845QX主要特性,框图,电源管理单元框图,统控制单元-数字模块框图和Cortex-M0框图,以及TLE984x评估板主要特性,框图,电路图,材料清单,PCB元件布局图和设计图.

This highly integrated circuit contains analog and digital functional blocks. For system and interface control anembedded 32-Bit Cortex-M0 microcontroller is included. For internal and external power supply purposes, on-chiplow drop-out regulators are existent. An internal oscillator (no external components necessary) provides a costeffective and suitable clock in particular for LIN slave nodes. As communication interface, a LIN transceiver andseveral High Voltage Monitor Inputs with adjustable threshold and filters are available. Furthermore two High-Sides Switches (e.g. for driving LEDs or powering of switches), two low-side switches (e.g. for relays) and severalgeneral purpose input/outputs (GPIO) with pulse-width modulation (PWM) capabilities are available.
