The AOZ18101DI-03 from Alpha & Omega Semiconductor is an Over-Voltage Protection eFuse IC that has been designed for applications that require front-end protection at the input line. It requires an input voltage from 3.5 V to 14 V and provides an output current of 5 A. This eFuse IC has an on-state resistance of 20 milli-ohms and can withstand an absolute voltage of up to 22 V on the input and output voltage pins. It has a programmable output soft start feature to control the inrush current for highly capacitive loads which in turn reduces the stress on the input power source.

This eFuse IC has a programmable internal current-limiting circuit to protect the supply from large load current. It also incorporates input under-voltage lockout (UVLO), input over-voltage output clamp (OVC), and thermal shut down protection (TSD) with an auto-restart version that activates during fault conditions to provide enhanced reliability and safety. This RoHS Compliant eFuse is available in a surface-mount package that measures 3 x 3 mm and is ideal for servers, HDD and SSD drivers, PCI cards, and networking applications.
