1. Description

The ATA6832 is a fully protected driver IC specially designed for high temperature

applications. In mechatronic solutions, for example turbo charger or exhaust gas recir-

culation systems, many flaps have to be controlled by DC motor driver ICs which are

located very close to the hot engine or actuator where ambient temperatures up to

150°C are usual. Due to the advantages of SOI technology junction temperatures up

to 200°C are allowed. This enables new cost effective board design possibilities to

achieve complex mechatronic solutions.

ATA6832

The ATA6832 is a triple half-bridge driver to control up to 3 different loads by a micro-

controller in automotive and industrial applications. Each of the 3 high-side and 3

low-side drivers is capable of driving currents up to 1.0A. Due to the enhanced PWM

signal (up to 25 kHz) it is possible to generate a smooth control of, for example, a DC

motor without any noise. The drivers are internally connected to form 3 half-bridges

and can be controlled separately from a standard serial data interface, enabling all

kinds of loads, such as bulbs, resistors, capacitors and inductors, to be combined.

The IC design especially supports the application of H-bridges to drive DC motors.

Protection is guaranteed with respect to short-circuit conditions, overtemperature and

undervoltage. Various diagnostic functions and a very low quiescent current in

standby mode enable a wide range of applications. Automotive qualification (protec-

tion against conducted interferences, EMC protection and 1.5-kV ESD protection)

gives added value and enhanced quality for exacting requirements of automotive

applications.
