The ATA6827 is a fully protected driver IC specially designed for high temperatureapplicaTIons. In mechatronic soluTIons, for example turbo charger or exhaust gas recirculaTIonsystems, many flaps have to be controlled by DC motor driver ICs which arelocated very close to the hot engine or actuator where ambient temperatures up to150°C are usual. Due to the advantages of SOI technology juncTIon temperatures upto 200°C are allowed. This enables new cost effective board design possibilities toachieve complex mechatronic solutions.The ATA6827 is a fully protected Triple Half-Bridge to control up to 3 different loads bya microcontroller in automotive and industrial applications. Each of the 3 high-side and3 low-side drivers is capable to drive currents up to 1.0A. The drivers are internallyconnected to form 3 half-bridges and can be controlled separately from a standardserial data interface. Therefore, all kinds of loads such as bulbs, resistors, capacitorsand inductors can be combined. The IC design especially supports the application ofH-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 standbymode opens a wide range of applications. Automotive qualification gives added valueand enhanced quality for exacting requirements of automotive applications.
