Si3406 Datasheet (Silicon Laboratories) - Fully-Integrated IEEE 802.3-Compliant POE+ PD Interface and High-Efficiency Switching Regulators

Si3406, Fully-Integrated IEEE 802.3-Compliant POE+ PD Interface and High-Efficiency Switching Regulators

Si3406x Family Data Sheet Fully-Integrated IEEE 802.3-Compliant POE+ PD Interface and High-Efficiency Switching Regulators with Sleep, Wake, and LED Drive The Si3406x family integrates all power management and control functions required in a Power-over-Ethernet Plus (PoE+) powered device (PD) application.

These devices convert the high voltage supplied over the 10/100/1000BASE-T Ethernet connection to a regulated, low-voltage output supply.

The optimized architecture of this device family minim

Si3406 Features

* can be utilized to minimize standby current, control sleep and wake states, and provide application status information using an LED. The Si3406 is available in a low-profile, 20-pin, 5 x 5 mm QFN package, and the Si34061 and Si34062 are available in low-profile, 24-pin, 5 x 5 mm QFN packages. KEY F
