AOZ18101DI-01 Image

The AOZ18101DI-01 from Alpha & Omega Semiconductor is a Current-Limiting Over-Voltage Protection eFuse IC that targets applications requiring front-end protection at the input line. It requires an input voltage of up to 14 V. This eFuse IC offers a soft-start function that can be programmed to control the inrush current for highly capacitive loads. It contains a built-in blocking FET for True Reverse Current Blocking (TRCB) and an external blocking FET control pin for application flexibility if a standalone MOSFET is preferred. This eFuse has an inbuilt current-limiting circuit to protect the power supply from high load current. It also includes a resistor to externally adjust the current limit threshold and automatically restart once the fault conditions are released.

This eFuse IC is equipped with built-in input under-voltage lockout (UVLO), input over-voltage output clamp (OVC), and thermal shutdown protection (TSD) circuits to prevent over-load-related damages. It is available in a surface-mount package that measures 3.10 x 3.10 mm and is ideal for servers, HDD and SSD drivers, PCI cards, and networking applications.
