WebSimilarly, for a PD chip that supports PoE+ loads, we can set the inrush current limit of its pass-FET (Q1) to ~200-300mA (during the regular PoE inrush phase), then let the current limit rise to ~ 1000mA after power-up is achieved; but if a wall adapter is detected, we can raise the current limit to say 1.8A.
WebInrush current is the instantaneous high input current drawn by a power supply or electrical equipment at turn-on. This arises due to the high initial currents required to charge the capacitors and inductors or transformers. The inrush current is also known as the switch–on surge, or the input surge current. WebInrush current. Inrush current, input surge current, or switch-on surge is the maximal instantaneous input current drawn by an electrical device when first turned on. Alternating-current electric motors and transformers may draw several times their normal full-load current when first energized, for a few cycles of the input waveform.
