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 RDS ON vertical DMOS power stages with CMOS control circuit. The protected high-side switch contains the control and diagnosis circuit. To achieve low RDS ON and fast switching performance, the low-side switches are manufactured in SFET 2 logic level technology.
