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.
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.
