Atmel ATA6843 汽车BLDC马达驱动解决方案
Atmel公司的 ATA6843和ATA6844是三相无刷直流马达（ BLDC）控制器，集成了微控制器和六个分立的功率MOSFET，并提供3.3V/5V线性稳压器和窗口看门狗，为汽车应用提供了完整的BLDC马达控制单员。工作电压5.25V到32V，工作结温150度C，能以最大开关频率50kHz直接驱动6个外接NMOS晶体管。本文介绍了ATA6843和ATA6844主要特性，方框图和典型应用电路及所用外接元件列表。
BLDC Motor Driver and LIN System Basis Chip
The Atmel® ATA6843 and Atmel ATA6844 are system basis chips for three-phase brushless DC motor controllers designed in Atmel’s state-of-the-art 0.8μm SOI technology SMART-I.S.™1. In combination with a microcontroller and six discrete power MOSFETs, the system basis chip forms a BLDC motor control unit for automotive applications. In addition, the circuits provide a 3.3V/5V linear regulator and a window watchdog.
