Resettable self-protected electronic fuse suits disk drives and industrial needs

Designed for consumer applications such as hard disk drives and industrial applications to enhance system reliability against catastrophic and shutdown failures, Digi-Key now stocks the Diodes Inc. NIS5135 self-protected resettable electronic fuse. To support a wide range of demanding applications, the design has been optimized to operate over the supply range of 3.1V to 18V. For robustness and protection, the device integrates a low RDS(ON) NMOS buffer power device along with an under-voltage lockout, overvoltage clamp, current limit, dv/dt control, and thermal-shutdown circuits. Thermal shutdown can be either latching type (NIS5135MN1) or auto-retry type (NIS5135MN2). Applications include hard disk drives, solid state drives, set-top boxes, DVD and Blu-ray disc drivers, motherboard power management, printer load power management and fan drives.
