Features
1. Description
The T6817 is a fully protected driver interface designed in 0.8-µm BCDMOS technol-
ogy. It can be used to control up to 6 different loads by a microcontroller in automotive
and industrial applications.
Each of the 3 high-side and 3 low-side drivers is capable of driving currents up to
600 mA. The drivers are 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 is especially supportive of
H-bridges applications to drive DC motors.
Protection is guaranteed in terms of short-circuit conditions, overtemperature, under-
and overvoltage. Various diagnosis functions and a very low quiescent current in
standby mode open a wide range of applications. Meeting automotive qualifications in
the area of conducted interferences, EMC protection and 2 kV ESD protection provide
added value and enhanced quality for the exacting requirements of automotive
applications.
