描述 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.
