Package
P-TO263-15-1
Description
The BTS 780 GP is part of the TrilithIC family containing one double high-side switch
and two low-side switches in one P-TO263-15-1 package.
“Silicon instead of heatsink”
becomes true
The ultra low RDS ON of this device avoids power dissipation. It saves costs in mechanical
construction and mounting and increases the efficiency.

The high-side switches are produced in the SMART SIPMOS® technology. They are fully
protected and contain the signal conditioning circuitry for diagnosis (the comparable
standard high-side product is the BTS 734L1).
For minimized RDS ON the two low-side switches are produced in S-FET logic level
technology (the comparable standard product is the BUZ 100SL).
Each drain of these three chips is mounted on separated leadframes (see Figure 1). The
sources of all four power transistors are connected to separate pins.
www.DataSheeSt4oU.ctohme BTS 780 GP 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.
