ATA6824C - High Temperature H-bridge Motor Driver

Description

The Atmel® ATA6824C is designed for DC motor control application in automotive high temperature environment like in mechatronic assemblies in the vicinity of the hot engine, e.g.

turbo charger.

Features

  • PWM and direction-controlled driving of four externally-powered NMOS transistors.
  • High temperature capability up to 200°C junction.
  • 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.
  • A pro.
