General Description

The ATA6837 is 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 and where ambient temperatures up to 150°C are usual.

Due to the advantages of SOI technology, junction temperatures up to 200°C are allowed.
