The BTM7740G is part of the Trilith IC 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 BTM7740G can be used in H-bridge- as well as in any other configuration. Both the double high-side and the two low-side switches of the BTM7740G are manufactured in SMART SIPMOS ® technology which combines low R DS ON vertical DMOS power stages with CMOS circuitry forcontrol, protection and diagnosis.
