• 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 150°C • Up to 1A Output Current • Very Low Quiescent Current IS < 20 µA in Standby Mode • 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 ATA6838 is a fully protected hex half-bridge driver designed in Smart Power SOI technology, 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.
