The product is an intelligent high-side power switch launched by Infineon. It uses a four-channel design, with a conduction resistance of 90 mΩ per channel, a rated load current of 3.3 A, and can provide switching control for 12V and 24V grounded loads. It has short circuit protection, overload protection, current limiting, thermal shutdown, overvoltage protection (including load dump), reverse battery protection, logic ground and load ground isolation, electrostatic discharge protection and other protection functions.
The BTS724G is a smart high‑side power switch featuring four parallel channels, each with a typical on‑state resistance of 90 mΩ. It integrates charge‑pump MOSFETs, diagnostic feedback, and a range of protection functions such as short‑circuit, overload, over‑voltage, reverse‑battery, and ESD protection.
The device operates from 5.5 V to 40 V, supports nominal load currents up to 3.3 A per channel (7.3 A when all four channels are paralleled), and is supplied in a P‑DSO‑20‑15 package. Detailed pin definitions, electrical characteristics, and timing diagrams are provided for designers.
