This document describes the features and applications of PROFET® ITS 640S2 Infineon Technologies AG, including short circuit protection, current limitation, proportional load current sense, CMOS compatible input, etc.
The PROFET® ITS640S2 is a Smart Sense high‑side power switch designed for industrial applications. It replaces electromechanical relays, fuses, and discrete circuits, offering short‑circuit protection, current limitation, and diagnostic feedback for 12 V and 24 V DC grounded loads.
Key specifications include an operating voltage range of 5.0‑34 V, on‑state resistance as low as 30 mΩ, and built‑in protection functions such as overload, undervoltage, overvoltage, reverse‑battery, and loss‑of‑ground detection. The device supports a wide temperature range (‑30 °C to +85 °C) and can handle up to 85 W of power dissipation.
