Analog Devices MAX5995x Power Management ICs provide a complete interface for Powered Device (PD) to comply with IEEE® 802.3af/at/bt standard in a Power-over-Ethernet (PoE) system. These devices provide the PD with a detection signature, classification signature, and an integrated isolation power switch with startup inrush current control. The MAX5995x ICs support a multi-event classification method as specified in the IEEE 802.3bt standard and provide a signal to indicate from Type 1 to Type 4 Power Sourcing Equipment (PSE). The MAX5995x PMICs also provide a Power-Good (PG) signal, two-step current limit and foldback control, and over-temperature protection.
