1.2 Description
The BTS 7741 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 lead frames. The sources are connected
to individual pins, so the BTS 7741 G 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
BTS 7741 G are manufactured in SMART SIPMOS
®
technology which combines low
R
DS ON
vertical DMOS power stages with CMOS control circuitry. The high-side switch is
fully protected and contains the control and diagnosis circuitry. Also the low-side
switches are fully protected, the equivalent standard product is the BSP 77.
In contrast to the BTS 7740 G, the BTS 7741 G offers an open load in Off-mode
detection and slightly increased current limitation.
