Description The ATA6833 and ATA6834 are system basis chips for three-phase brushless DC motor controllers designed in Atmel ®’s state-of-the-art 0.8 µm SOI technology SMART-I.S. ™1. In combination with a microcontroller and six discrete power MOS- FETs, 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. The circuit includes various control and protection functions like overvoltage and over- temperature protection, short circuit detection, and undervoltage management. Thanks to these function blocks, the driver fulfils a maximum of safety requirements and offers a high integration level to save cost and space in various applications. The target applications are most suitable for the automotive market due to the robust tech- nology and the high qualification level. ATA6834, in particular, is designed for applications in a high-temperature environment. BLDC Motor Driver and LIN System Basis Chip ATA6833 ATA6834 Preliminary 9122D–AUTO–09/09 |
