The MAX5982A/MAX5982B/MAX5982C provide a completeinterface for a powered device (PD) to comply withthe IEEE® 802.3af/at standard in a power-over-Ethernet(PoE) system. The MAX5982A/MAX5982B/MAX5982Cprovide the PD with a detection signature, classificationsignature, and an integrated isolation power switchwith inrush current control. During the inrush period,the MAX5982A/MAX5982B/MAX5982C limit the currentto less than 182mA before switching to the higher currentlimit (1700mA to 2100mA) when the isolation powerMOSFET is fully enhanced. The devices feature an inputUVLO with wide hysteresis and long deglitch time tocompensate for twisted-pair cable resistive drop and toassure glitch-free transition during power-on/-off conditions.The MAX5982A/MAX5982B/MAX5982C can withstandup to 100V at the input.
