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 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.
The circuit includes various control and protection functions like overvoltage and overtemperature
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 technology
and the high qualification level. ATA6834, in particular, is designed for
applications in a high-temperature environment.
