Atmel ATA6833/ATA6834 BLDC Motor Driver and LIN System Basis Chip DATASHEET ● Atmel ATA6833 temperature range TJ = 150°C ● Atmel ATA6834 extended temperature range TJ = 200°C ● Direct driving of 6 external NMOS transistors with a maximum switching frequency of 50kHz ● Integrated charge pump to provide gate voltages for high-side drivers and to supply ESD performance ● QFN48 package 7mm x 7mm The ATA6833 and Atmel ATA6834 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 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. Atmel ATA6834, in particular, is designed for applications in a high-temperature environment.
