Siemens BTS 780 Datasheet
The BTS 780 is a trilithic power‑MOSFET driver that integrates one high‑side switch and two low‑side switches in a single P‑TO263‑15‑1 package. It offers configurable bridge operation, ultra‑low on‑resistance, very low quiescent current and a range of protection functions for automotive and industrial applications.
The document details the pin layout, functional block diagram, input and output stage behavior, diagnosis and protection mechanisms such as short‑circuit, over‑temperature, under‑ and over‑voltage lockout, and open‑load detection, as well as package dimensions and typical electrical characteristics.

Questions answered in these manuals
What is the typical on‑resistance of the high‑side switch?
The high‑side switch has a typical RDS(on) of 35 mΩ at 25 °C.
What package does the BTS 780 use?
The device is supplied in a P‑TO263‑15‑1 plastic transistor single outline package.
What is the maximum supply voltage for the BTS 780?
The device operates up to 40 V.
How does the BTS 780 protect against over‑temperature conditions?
It includes an over‑temperature protection circuit with hysteresis that shuts off the output transistors and sets the status output low.
