Industrial SPoE powered-device controller supports IEEE 802.3cg single-pair Power over Ethernet applications. The device operates from a 2.3 V to 60 V input range and includes polarity correction using external low-side N-channel MOSFETs. SCCP-based classification, a wakeup signature, and a 3.5 V standby regulator support classification-based building and factory automation systems. Lead-free orderable versions are specified in 12-pin DFN and 12-pin MSOP packages with exposed pads for a -40 °C to 150 °C junction temperature range.
