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.
