TPS25942ARVCR Electronic eFuse IC 5.5V 4A
The TPS25942ARVCR is an advanced 5.5V, 4A eFuse (electronic fuse) with integrated MOSFET and comprehensive protection features, designed for robust power distribution and system protection in space-constrained applications. This highly integrated device in a tiny 2.5mm × 2.5mm WQFN package provides precise current limiting, adjustable slew rate control, and fast short-circuit protection, making it ideal for hot-swap, power multiplexing, and load management in servers, networking equipment, and portable electronics. Operating from a 2.5V to 5.5V input range, the TPS25942 combines ultra-low 10.5mΩ RDS(ON) with 4A continuous current capability, achieving high efficiency while providing multiple fault protection mechanisms including overcurrent, overvoltage, undervoltage, and thermal shutdown protection, ensuring system reliability under various fault conditions.
TPS25942ARVCR Applications
The TPS25942ARVCR is extensively used in server and storage systems for hot-swap power control, PCIe card protection, and board-level power sequencing applications. It serves critical roles in networking equipment including routers, switches, and base stations for port protection and power management. Industrial automation systems utilize this eFuse for PLC I/O protection, motor drive interfaces, and distributed power distribution with fault reporting. The device is also employed in test and measurement equipment, medical devices, and automotive infotainment systems where its compact size and comprehensive protection features provide reliable power management solutions while minimizing board space requirements.
