SGM2545
2.7V to 23V, 5.5A, 29mΩ eFuse with True Reverse Current Blocking and Supporting Input Reverse Polarity Protection
The SGM2545 is a compact electronic fuse (eFuse) with a full suite of protection functions. With very few external components, the SGM2545 can provide multiple protection modes. To encounter overloads, short-circuit, voltage surges, high inrush current and reverse polarity, the device is suitable as a robust defense. Due to the back-to-back FETs packaged inside the chip, SGM2545 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. The SGM2545 has almost zero DC reverse current by adopting a linear ORing based scheme, mimicking ideal diode behavior with minimum power dissipation and forward voltage drop.
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. In case of output overload, the device actively limits the current or disconnects the circuit. The output current limit threshold and the transient over-current blanking timer can be adjusted by the user. The ILIM pin is also used for load current monitoring.
The SGM2545 is available in a Green TQFN-2×2-10L package.
