Diodes' NIS5135 is a self-protected resettable electronic fuse designed for consumer applications, such as hard disk drives, to industrial applications to enhance system reliability against catastrophic and shutdown failures. To support a wide range of demanding applications, the design has been optimized to operate over the supply range of 3.1 V to 18 V.

For robustness and protection, the device integrates a low R_DS(ON) NMOS buffer power device along with an undervoltage 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).
