SGM2548
2.7V to 23V, 5.5A Electronic Fuse with Ideal Diode Function, Input Reverse Polarity and Over-Voltage Protection
The SGM2548 is a compact electronic fuse (eFuse) with a full suite of protection functions. With very few external components, the SGM2548 can provide multiple protection modes. To encounter overload, short-circuit, high inrush current, voltage surge and reverse polarity, the device is suitable as a robust defense.
Due to the back-to-back FETs packaged inside the chip, SGM2548 prohibits reverse current flow from output to input, which is ideal for power MUX/ORing applications and systems requiring load side energy hold up storage when input power supply fails. Through linear ORing circuit architecture, these devices effectively suppress reverse DC current to negligible levels and approximate perfect diode functionality, with carefully engineered minimization of both voltage drop across the forward path and associated energy dissipation.
The VOUT rise time can be programmed by setting an additional capacitor to the SS pin, which can minimize inrush current. Programmable over-voltage protection is used to turn off the device or clamp the output to a fixed voltage (pin-selectable) if the IN rises over a threshold value. The IMON pin is used for load current monitoring. In case of output overload, the device actively senses the current or disconnects the circuit.
The SGM2548 is available in a Green TQFN-2×2-10L package.
