The BTS441TG from Infineon is a single channel, N-channel power switch with a peak current of 17A. It is a high-side switch, meaning it is placed between the power supply and the load. This device is designed for industrial equipment, automotive applications, and consumer electronics, offering a number of safety features such as overload, short-circuit and thermal protection. It offers a wide voltage range, with built-in oscillator and digital isolated feedback for precise operation and current control. It also features an integrated level-shift circuit, allowing for compatibility between low-side and high-side applications.
