ATA6843 BLDC Motor Driver

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 un.
