Type Ordering Code Package BTS 780 on request P-TO263-15-1
Description The BTS 780 is a Trilith IC contains one double high-side switch and two low-side switches in one P-TO263-15-1.
“Silicon instead of heatsink” becomes true
The ultra low RDS
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 734L1).

Frequently Asked Questions
What kinds of input signals are supported by this device?
The control inputs (GH1, GH2) consist of TTL/CMOS compatible Schmitt-Triggers with hysteresis.
Does the BTS 780 support multiple connection configurations?
Yes, it can be used in H-Bridge configuration or any other switch setup because its sources are connected to separate pins.
What fault protection features does the device offer?
It provides built-in protection against load and GND short circuits, overtemperature shutdown with hysteresis, and open-load detection.
