1. Description
The ATA6829 is a fully protected driver interface designed in 0.8-µm BCDMOS tech-
nology. It is used to control up to six different loads by a microcontroller in automotive
and industrial applications.
Each of the three high-side and three low-side drivers is capable to drive currents up
to 1.5A. Each driver is freely configurable 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 design especially supports the
applications of H-bridges to drive DC motors. The capability to control each output
with an external PWM signal opens additional applications.
Protection is guaranteed regarding short-circuit conditions, overtemperature and
undervoltage. Various diagnostic functions and a very low quiescent current in
stand-by mode opens 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.
