This document describes the features and characteristics of the TrilithIC BTS 780 GP product, including quad switch driver, configurable as bridge or quad-switch, optimized for DC motor management applications, ultra low RDS ON, high peak current capability, low quiescent current, etc.
The BTS 780 GP is a quad switch driver from Infineon's TrilithIC family, featuring a high‑side and two low‑side switches in a compact P‑TO263‑15‑1 package. It offers configurable bridge or quad‑switch operation, ultra‑low on‑resistance, high peak current capability, and a range of protection functions for automotive and industrial applications.
The document details the pin configuration, input and output circuit behavior, protection mechanisms such as short‑circuit, over‑temperature, under‑ and over‑voltage lockout, and status flag diagnostics. Package dimensions, test‑PCB layout, and mechanical drawing information are also included.
| High‑side switch typical on‑resistance | 34 mΩ @ 25 °C |
|---|---|
| Low‑side switch typical on‑resistance | 15 mΩ @ 25 °C |
| Peak current capability | 44 A @ 25 °C |
| Quiescent current | 15 pA @ 25 °C |
| Maximum operating voltage | 36 V |
| Status flag outputs | 2‑bit open‑drain status flags (ST1, ST2) |
The high‑side switch has a typical on‑resistance of 34 mΩ at 25 °C.
The device operates up to 36 V.
