资料介绍
The ATA6839 is designed for high-temperature applications. In mechatronic solutions,
for example, turbo charger or exhaust gas recirculation systems, many flaps have to
be controlled by DC motor driver ICs which are located very close to the hot engine or
actuator and where ambient temperatures up to 150°C are usual. Due to the advantages
of SOI technology, junction temperatures up to 200°C are allowed. This enables
new cost-effective board design possibilities to achieve complex mechatronic
solutions.
The ATA6839 is a fully protected hex half-bridge driver, 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.
