Description
The T6818/T6828 are fully protected driver interfaces designed in 0.8-µm BCDMOS
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 combined. The IC design especially
supports the application of H-bridges to drive DC motors.www.DataSheet4U.com
Protection is guaranteed regarding short-circuit conditions, overtemperature and und-
er voltage. Various diagnostic functions and a ver y 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.
