1. Description

The T6818/ATA6828 are fully protected driver interfaces designed in 0.8-µm BCD-

MOS technology. They are 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 to drive currents up to 1.5 A.

The drivers are internally connected to form 3 half-bridges and can be controlled sep-

arately from a standard serial data interface. Therefore, all kinds of loads such as

bulbs, resistors, capacitors and inductors can be

supports the application of H-bridges to drive DC motors.

Protection is guaranteed regarding short-circuit conditions, overtemperature and und-

ervoltage. Various diagnostic functions and a very low quiescent current in

stand-by-mode opens a wide range of applications. Automotive qualification (protec-

tion against conducted interferences, EMC protection and 2-kV ESD protection) gives

added value and enhanced quality for exacting requirements of automotive

applications.
