Infineon BTS7741G

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 RDSON 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.
