The ATA6831 provides fully protected driver interfaces designed in SOI technology. They are used to allow a microcontroller to control up to 3 different loads in automotive and industrial applications. Each of the 3 high-side and 3 low-side drivers is capable of driving currents up to 1.0A. Due to the enhanced PWM signal (up to 25 kHz) it is possible to generate a smooth control of, for example, a DC motor without any noise. The drivers are internally connected to form 3 half-bridges and can be controlled separately from a standard serial data interface, enabling all kinds of loads, such as bulbs, resistors, capacitors and inductors, to be combined. The IC design especially supports the application of H-bridges to drive DC motors. Protection is guaranteed with respect to short-circuit conditions, overtemperature and undervoltage. Various diagnostic functions and a very low quiescent current in standby mode enable a wide range of applications. Automotive qualification (protection against conducted interferences, EMC protection and 2-kV ESD protection) gives added value and enhanced quality for exacting requirements of automotive applications.
