The SI3402-C-GMR is a Power-over-Ethernet (PoE) powered device (PD) controller from Skyworks Solutions. It integrates the power management and control functions needed to convert the high voltage supplied over a 10/100/1000BASE-T Ethernet connection into a regulated low-voltage output. The device includes the required diode bridges and transient surge suppressor, enabling direct connection to an RJ-45 connector.
The controller supports a single channel and operates from a supply voltage of 2.8V to 57V. It is capable of delivering 15W of output power and draws 2mA of current. The integrated switching regulator supports both isolated (flyback) and non-isolated (buck) converter topologies, and the internal switching FET is included. The SI3402-C-GMR is rated for operation across -40°C to 85°C.
The device complies with IEEE 802.3af (PoE) and IEEE 802.3at (PoE+) standards, supporting Type 1 (Class 3 and below) powered device applications. It integrates transient overvoltage protection, undervoltage lockout, thermal shutdown, and foldback current limiting. The SI3402-C-GMR is a pin-compatible replacement for the obsolete SI3402-A and is available in a 20-QFN (5x5) or 20-VQFN exposed pad package for surface-mount assembly.
