Description
Package
P-DSO-28-14
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
廬
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.
