ATA6823C - H-bridge Motor Driver

General Description

The Atmel® ATA6823C is designed for automotive body and powertrain applications.

The IC is used to drive a continuous current motor in a full H-bridge configuration.

Key Features

  • PWM and direction-controlled driving of four externally-powered NMOS transistors.
  • A programmable dead time is included to avoid peak currents within the H-bridge.
  • Integrated charge pump to provide gate voltages for high-side drivers and to supply the gate of the external battery reverse protection NMOS.
  • 5V/3.3V regulator and current limitation function.
  • Reset derived from 5V/3.3V regulator output voltage.
  • Sleep mode with supply current of typically < 45µA, wake-up.
