onsemi Current Regulation/Management NIS4461MT1TXG

The NIS4461MT1TXG is an electronic fuse designed to provide overcurrent protection for downstream circuitry, particularly in applications such as hard drives, motherboards, and portable instruments. It operates within an input voltage range of 9 to 24 volts and features a typical current limit of 4.2 amps. The device includes an internal charge pump and an undervoltage lockout circuit, enhancing its reliability and performance. This eFuse is thermally protected and does not require an external current shunt, simplifying integration into various designs. It is rated for ESD protection up to 2000 V for both the Human Body Model and Charged Device Model, ensuring robustness against electrostatic discharge. The NIS4461MT1TXG is also compliant with RoHS standards, being Pb-free and halogen-free. Its compact WDFN10 package facilitates space-efficient designs.
