1. Description

The T6819/ATA6829 are fully protected driver interfaces designed in 0.8-µm BCD-

MOS technology. They are used to control up to six different loads by a

microcontroller in automotive and industrial applications.

Each of the three high-side and three low-side drivers is capable to drive currents up

to 1.5A. Each driver is freely configurable 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

applications of H-bridges to drive DC motors. The capability to control each output

with an external PWM signal opens additional applications.

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 (protection against

conducted interferences, EMC protection and 2-kV ESD protection) gives added value

and enhanced quality for exacting requirements of automotive applications.
