ATA6827 High Temperature Triple Half-Bridge Driver

The ATA6827 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 t.
