1. Description
The ATA6826 is a fully protected Triple Half-bridge designed in Smart Power SOI
Technology, used 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 of driving 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.
