The Infineon BTS441RG is a single-channel smart power high-side switch built with N-channel vertical power FET technology. It is designed for 5V, 12V, and 24V DC applications, replacing electromechanical relays and fuses.
Key electrical specifications include a maximum on-state resistance of 20 mΩ at 150°C, an operating voltage range of 4.75V to 41V, a nominal load current of 21A, and a current limitation of 65A. It offers very low standby current and is compatible with µC and CMOS inputs.
Integrated protection functions include short circuit, current limitation, overload, thermal shutdown, overvoltage protection, reverse battery protection, loss of ground, and loss of Vbb protection. Diagnostic functions provide open drain output for feedback on open load detection and thermal shutdown.
This device comes in a PG-TO263-5 surface-mount package and is AEC Qualified. It is suitable for various load types, including resistive, inductive, and capacitive loads, and is particularly useful for loads with high inrush currents like lamps.
