The SGM2537 family is a compact electronic fuse (eFuse) with circuit protection functions, which can be used as a solution to power management. The FET hot-swap device is also highly integrated in a small package. With very few external components, the SGM2537 can provide multiple protection modes. To encounter overloads, voltage surges, short-circuits and high inrush current, the device is suitable as a robust defense.

A single external resistor can be used to set the output current limit, and after detecting the voltage drop across the resistor, it is possible to monitor the load current accurately. Also, a single external capacitor is enough to set the output slew rate for applications with particular inrush current requirements. Using internal clamping circuits alone can quickly limit over-voltage events to a fixed maximum value within a safe range.

The SGM2537 is available in a Green TDFN-2×2-8AL package.
