The PROFET® ITS621L1 is a smart two-channel high side power switch from Infineon. The product features overload protection, current limitation, short circuit protection, thermal shutdown, overvoltage protection (including load dump), fast demagnetization of inductive loads, reverse battery protection, undervoltage and overvoltage shutdown with auto-restart and hysteresis, open drain diagnostic output, open load detection in ON-state, CMOS compatible input, loss of ground and loss of Vbb protection, and electrostatic discharge (ESD) protection. It is suitable for 12 V and 24 V DC grounded loads in industrial applications and can replace electromechanical relays, fuses, and discrete circuits.
The Infineon ITS621L1 is a smart two‑channel high‑side power switch designed for industrial applications. It integrates overload, over‑voltage, short‑circuit, thermal shutdown, reverse‑battery and ESD protection, and provides diagnostic feedback via an open‑drain status output.
The document lists detailed electrical and thermal characteristics, pin functions, maximum ratings, and protection features. It also includes the truth table, package information, and ordering codes for the PG‑TO220AB/7 package.
The device operates from –30 °C to +85 °C.
