• Six Half-bridge Outputs Formed by Six High-side and Six Low-side Drivers • Capable of Switching all Kinds of Loads Such as DC Motors, Bulbs, Resistors, Capacitors and Inductors • RDSon Typically at 25°C, Maximum at 200°C • Up to 1A Output Current • Outputs Short-circuit Protected • Overtemperature Prewarning and Protection • Undervoltage Protection • Various Diagnosis Functions Such as Shorted Output, Open Load, Overtemperature and Power Supply Fail • Serial Data Interface • Operation Voltage up to 40V • Daisy Chaining Possible • Serial Interface 5V Compatible, up to 2 MHz Clock Frequency • QFN24 Package The ATA6839 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. This enables new cost-effective board design possibilities to achieve complex mechatronic solutions. The ATA6839 is a fully protected hex half-bridge driver, used to control up to 6 different loads 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 to 1A. The drivers are internally connected to form 6 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 especially supports the application of H-bridges to drive DC motors. Protection is guaranteed in terms of short-circuit conditions, overtemperature and undervoltage. Various diagnosis functions and a very low quiescent current in standby mode make a wide range of applications possible. Automotive qualification referring to conducted interferences, EMC protection and ESD protection gives added value and enhanced quality for the exacting requirements of automotive applications.
