The SGM25120 is a hot-plug protection device providing dual-directional protection: it safeguards its output circuit from input-induced transients while simultaneously shielding its input from harmful short circuits and transient events originating from the output side.
The device includes an IMON option that generates a voltage proportional to the power supply current through the power supply device, which is set by the resistance of IMON pin to ground. An integrated high-efficiency charge pump drives the gate of the power MOSFET, enabling ultra-low-loss power delivery through enhanced power device with an extremely low on-resistance of 1.9mΩ to turn on.
During start-up, the output slew rate control mechanism, implemented via an external capacitor on the SS pin effectively suppresses inrush current. A dynamic current limiting unit, based on FET detection topology and combined with a precision resistor from the ILIM pin to the ground, supports programmable load current thresholds.
Full protection features include damaged MOSFET detection, current limit, thermal shutdown, over-voltage protection, and under-voltage protection.
The SGM25120 is available in a Green TLGA-4×4-24AL package.
