BTS 774 G Q67007-A9336 P-DSO-28-9
Description
The BTS 774 G is a TrilithlC contains one double high-side switch and two Iow-side
switches in one P-DSO-28-9 -Package.
"Silicon instead of heatsink"
becomes true
The ultra low Ros ON of this device avoids powerdissipation. It saves costs in mechanical
construction and mounting and increases the efficiency.
The high-side switches are produced in the SIEMENS SMART SIPMOS® technology. It
is fully protected and contains the signal conditioning circuitry for diagnosis. (The
comparable standard high-side product is the BTS 611L1.)

SIEMENS BTS 774G
For minimized RDS ON the two Iow-side switches are N channel vertical power FETs in the
SIEMENS SMART SIPMOS® technology. Fully protected by embedded protection
functions. (The comparable standard product is the BSP 78).
Each drain of these three chips is mounted on separated leadframes (see P-DSO-28-9
pin configuration). The sources of all four power transistors are connected to separate
So the BTS 774 G can be used in H-Bridge configuration as well as in any other switch
configuration.
Moreover, it is possible to add current sense resistors.
All these features open a broad range of automotive and industrial applications.
