The IS6108A is programmable hot swap e-fuse for high current applications such as servers, data storage, and communication products. They contain a high-side MOSFET and other control circuitry that enables them to work as stand-alone devices, or to be controlled by a hot-swap controller. The IS6108A drives up to 60 A of continuous current per device. 

The IS6108A limit the inrush current to the load when a circuit card is inserted into a live backplane power source, thereby limiting the back plane's voltage drop. During the initial startup, the device current is controlled by using the slew rate at the output. This slew rate can be programmed by an external capacitor at the SS pin.

The devices offer many features to simplify system designs. They provide an integrated solution for monitoring output current and die temperature.

 The IS6108A is designed with a full suite of protection functions. It includes output current limiting, over temperature shutdown, and power FET detection. The IS6108A/C detect the power FET gate, source, and n short conditions, in addition to feedback to the controller. Also, the parts can be operated in parallel for high-current applications.
