This document describes the features and characteristics of the BTS 7810 K product, including quad D-MOS switch, configurable as bridge or quad-switch, optimized for DC motor management applications, low RDS ON, maximum peak current, very low quiescent current, etc.
The BTS 7810 K is a quad D‑MOS switch from Infineon's TrilithIC family, configurable as a bridge or quad‑switch and optimized for DC motor management. It integrates low RDS ON high‑side and low‑side switches, status flags, and a range of protection functions.
Key specifications include a typical high‑side on‑resistance of 26 mΩ, low‑side on‑resistance of 14 mΩ, a typical peak current of 42 A, and a very low quiescent current of 4 µA. The device operates from 0.3 V to 42 V and features over‑temperature shutdown, load short‑circuit protection, open‑load detection, and undervoltage lock‑out. This manual is written in Chinese.
