ATA6844 - BLDC Motor Driver

Download the ATA6844 datasheet PDF. This datasheet also covers the ATA6843 variant, as both devices belong to the same bldc motor driver family and are provided as variant models within a single manufacturer datasheet.

Description

The Atmel® ATA6843 and Atmel ATA6844 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.

Features

  • Broad operation voltage range from 5.25V to 32V.
  • Atmel® ATA6843 temperature range TJ = 150°C.
  • Atmel ATA6844 extended temperature range TJ = 200°C.
  • Direct driving of six external NMOS transistors with a maximum switching frequency of 50kHz.
  • Integrated charge pump to provide gate voltages for high-side drivers and to supply the gate of the external battery reverse protection NMOS.
  • Built-in 5V/3.3V voltage regulator with current limitation.
  • Reset signal for the m.
