Product Brief
BTM 7750G
Trilith IC
T H E B T M 7 7 5 0 G is part of the Trilith IC family containing three dies in
Features
one package: One double high-side switch and two low-side switches. The drains
■
Quad D-MOS switch driver
of these three vertical DMOS chips are mounted on separated lead frames.
■
Free configurable as bridge or
quad-switch
The sources are connected to individual pins, so the BTM 7750G can be used in
BDTIC
H-bridge- as well as in any other configuration. Both the double high-side and
