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. The ATA6827 is a fully protected Triple Half-Bridge to control up to 3 different loads by a microcontroller in automotive and industrial applications. Each of the 3 high-side and 3 low-side drivers is capable to drive currents up to 1.0A. The drivers are internally connected to form 3 half-bridges and can be controlled separately from a standard serial data interface. Therefore, all kinds of loads such as bulbs, resistors, capacitors and inductors can be combined. The IC design especially supports the application of H-bridges to drive DC motors. Protection is guaranteed regarding short-circuit conditions, overtemperature and undervoltage. Various diagnostic functions and a very low quiescent current in standby mode opens a wide range of applications. Automotive qualification gives added value and enhanced quality for exacting requirements of automotive applications.
