ATA6844 Datasheet Bldc Motor Driver

Manufacturer: Atmel (now Microchip Technology)

Overview: ATA6843/ATA6844 BLDC Motor Driver and LIN System Basis Chip DATASHEET.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General 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.

In bination 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.

Key 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.
