1. Description

The ATA6836 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

650 mA. The drivers are internally connected to form 6 half-bridges and can be con-

trolled separately from a standard serial data interface. Therefore, all kinds of loads,

such as bulbs, resistors, capacitors and inductors, can be combined. The IC espe-

cially 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.
