1. Description  
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 automo-  
tive 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 inter-  
nally 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 (protec-  
tion against conducted interferences, EMC protection and 2-kV ESD protection) gives  
added value and enhanced quality for exacting requirements of automotive  
applications.
