●Description
●The BTS 7700 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 7700 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 BUZ 104 SL.
●In contrast to the BTS 7710 G, which consists of lower ohmic chips in the same package, the BTS 7700 G offers a lower price for applications, which do not need the high current capability of the BTS 7710 G or BTS 7710 GP.
