This file introduces the product features of the BTS 780 quad switch driver, including quad switch driver, free configurable as bridge or quad-switch, optimized for DC motor management applications, ultra low RDS ON @ 25 °C: High-side switch: typical 35 mΩ, Low-side switch: typical 15 mΩ, very high peak current capability, very low quiescent current, space- and thermal optimized SMD-Power-Package, load and GND-short-circuit-protected, operates up to 40 V, 2-bit status flag diagnosis, overtemperature shut down with hysteresis, short-circuit detection and diagnosis, open-load detection and diagnosis, C-MOS compatible inputs, internal clamp diodes, isolated sources for external current sensing, over- and under-voltage detection with hysteresis.
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.
