The ATA6839 is designed for high-temperature applications. In mechatronic solutions,for example, turbo charger or exhaust gas recirculation systems, many flaps have tobe controlled by DC motor driver ICs which are located very close to the hot engine oractuator and where ambient temperatures up to 150°C are usual. Due to the advantagesof SOI technology, junction temperatures up to 200°C are allowed. This enablesnew cost-effective board design possibilities to achieve complex mechatronicsolutions.The ATA6839 is a fully protected hex half-bridge driver, used to control up to 6 differentloads by a microcontroller in automotive and industrial applications.Each of the six high-side and six low-side drivers is capable of driving currents up to1A. The drivers are internally connected to form 6 half-bridges and can be controlledseparately from a standard serial data interface. Therefore, all kinds of loads, such asbulbs, resistors, capacitors and inductors, can be combined. The IC especially supportsthe application of H-bridges to drive DC motors.Protection is guaranteed in terms of short-circuit conditions, overtemperature andundervoltage. Various diagnosis functions and a very low quiescent current in standbymode make a wide range of applications possible.Automotive qualification referring to conducted interferences, EMC protection andESD protection gives added value and enhanced quality for the exacting requirementsof automotive applications.
