Description
Package
P-DSO-28-14
The
BTS 7740 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 7740 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 7740 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 7750 G,
which consists of lower ohmic chips in the same
package, the
BTS 7740 G
offers a lower price for applications, which do not need the
high current capability of the
BTS 7750 G
or
BTS 7750 GP.
