1. Description
The Atmel® ATA6836 is a fully protected hex half-bridge driver designed in Smart
Power SOI technology, used to control up to six 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
650mA. The drivers are internally connected to form six 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.
