1.2 Description
The BTS 7811K is part of the TrilithIC family containing three dies in one package:
One double high-side switch and two low-side switches. The drains of these three
vertical DMOS chips are mounted on separated leadframes. The sources are connected
to individual pins, so the BTS 7811K can be used in H-bridge- as well as in any other
configuration. The double high-side is manufactured in SMART SIPMOS^® technology
which combines low R_{DS ON} vertical DMOS power stages with CMOS control circuit. The
protected high-side switch contains the control and diagnosis circuit. To achieve low
R_{DS ON} and fast switching performance, the low-side switches are manufactured in S-
FET 2 logic level technology.
