ATA6833

ATA6834

1. 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.

Preliminary

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.
