Quad DMOS Switch Driver 28-Pin DSO

The BTS 7750 G 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 7750 G 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 circuitry. The high-side switch is fully protected and contains the control and diagnosis circuitry. To achieve low RDS ON and fast switching performance, the low-side switches are manufactured in S-FET logic level technology. The equivalent standard product is the BSP 78.
