NIS5135 Datasheet | Diodes Incorporated

Description The 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 3.1V to 18V. For robustness and protection, the device integrates a low RDS(ON) NMOS buffer power device along with an undervoltage lockout, overvoltage clamp, a current limit, a dv/dt control and a thermal shutdown circuit. The overvoltage circuit limits the output voltage without shutting the device down to allow the load to continue operating during overvoltage. Thermal shutdown can be either latching type (NIS5135MN1) or auto-retry type (NIS5135MN2).
