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 recirculation 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.
