U6815BM
Description
The U6815BM is a fully protected driver interface designed in 0.8-µm BCDMOS tech-
nology. It is used to control up to 12 different loads by a microcontroller in automotive
and industrial applications.
Each of the 6 high-side and 6 low-side drivers is capable to drive 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 especially supports the
applications of H-bridges to drive DC motors.
Protection is guaranteed in terms of short-circuit conditions, overtemperature, under-
and overvoltage. Various diagnostic functions and a very low quiescent current in
standby mode enable a wide range of applications. Automotive qualification referring
to conducted interferences, EMC protection and 2-kV ESD protection gives added
value and enhanced quality for the strict automotive requirements.
