Description

The BPI-9460 series of modules are designed to extract power from a conventional twisted pair Category 5 Ethernet cable, conforming to the IEEE 802.3af Power-over-Ethernet(PoE) standard. The BPI-9460 signature and control circuit provides the PoE compatibility signature and power classification required by the Power Sourcing Equipment (PSE) before applying up to 15W power to the port. The RT9460 provides a Class 0 signature.The DC/DC converter operates over a wide input voltage range and provides a regulated output. The DC/DC converter also has built-in short-circuit output protection.

Applications

  • IP Cameras
  • Wireless access point

Note

  • 1: With minimum load
  • 2: See Section Operating Temperature Range
    • Extended use close to, or at the maximum operating temperature can reduce the life time of the device.

Pin Description:

Pin # Name Description
1 VA1 RX Input (1). This input pin is used in conjunction with VA2 and connects to the centre tap of the transformer connected to pins 1&2 of the RJ45 connector (RX) - it is not polarity sensitive.BPI-9460S this pin is direct Input +. This pin connects to the positive (+) output of the input bridge rectifier.
2 VA2 TX Input (2). This input pin is used in conjunction with VA1 and connects to the centre tap of the transformer connected to pins 3&6 of the RJ45 connector (TX) - it is not polarity sensitive.BPI-9460S this pin is direct Input -. This pin connects to the negative (-) output of the input bridge rectifier.
3 VB1 Direct Input (1). This input pin is used in conjunction with VB2 and connects to pin 4 & 5 of the RJ45 connector - it is not polarity sensitive.BPI-9460S this pin is direct Input +. This pin connects to the positive (+) output of the input bridge rectifier.
4 VB2 Direct Input (2). This input pin is used in conjunction with VB1 and connects to pin 7 & 8 of the RJ45 connector - it is not polarity sensitive.BPI-9460S this pin is direct Input -. This pin connects to the negative (-) output of the input bridge rectifier
5 -VDC DC Return. This pin is the return path for the +VDC output.
6 +VDC DC Output. This pin provides the regulated output from the DC/DC converter.
7 ADJ Output Adjust. The output voltage can be adjusted from is nominal value, by connecting an external resistor from this pin to either the +VDC pin or the -VDC pin.
