The ATA6827 is a fully protected driver IC specially 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 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 ATA6827 is a fully protected Triple Half-Bridge to control up to 3 different loads by
a microcontroller in automotive and industrial applications. Each of the 3 high-side and
3 low-side drivers is capable to drive currents up to 1.0A. The drivers are internally
connected to form 3 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 design especially supports the application of
H-bridges to drive DC motors.
Protection is guaranteed regarding short-circuit conditions, overtemperature and undervoltage.
Various diagnostic functions and a very low quiescent current in standby
mode opens a wide range of applications. Automotive qualification gives added value
and enhanced quality for exacting requirements of automotive applications.
