ATA6836C-TIQW

The Atmel ATA6836C 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 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.
