The ATA6838 is a fully protected hex half-bridge driver designed in Smart Power SOI
technology, 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.
