BTS 781 GP
1.2
The BTS 781 GP is part of the TrilithIC
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 781 GP can be used in H-bridge- as well as in any other
configuration. The double high-side is manufactured in SMART SIPMOS
which combines low
high-side switch is fully protected and contains the control and diagnosis circuit. To
achieve low
manufactured in S-FET 2 logic level technology. The equivalent standard product is the
SPD30N06S2L-13.
