Description

The BTM7811K 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 lead frames.

The sources are connected to individual pins, so the BTM7811K can be used in H-bridge- as well as in any other

configuration. The double high-side switch is manufactured in SMART SIPMOS

technology which combines low

DS ON

vertical DMOS power stages with CMOS circuitry for control, protection and diagnosis. To achieve low

DS ON

and fast switching performance, the low-side switches are manufactured in S-FET logic level technology.
