2. Description
The Ag8000 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.
IEEE 802.3af allows for two power options for Category 5 cables and the Ag8000 series have
two pairs of power inputs pins: - VA1&2 and VB1&2 to accommodate this, see Figure 1.
The Ag8000 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 Ag8000 is compatible with Class 0 to Class 3 equipment.
The high efficiency DC/DC converter operates over a wide input voltage range and provides a
non-isolated regulated low ripple and low noise output. The DC/DC converter also has built-in
output overload, output short-circuit and over-temperature protection.

5.4. Power Classification
This is optional from the PSE and is used for power management. The Ag8000 allows the
current class to be externally programmed by connecting a resistor between the CP1 and
CP2 pins, see Figure 4: Class Programming Option. If no resistor is fitted the Ag8000 will
default to Class 0, a full list of programming resistor values are shown in Table 2: Class
Programming.

5.5. DC/DC Converter
The Ag8000’s DC/DC converter provides a non-isolated regulated low ripple and low noise
output, that has built-in overload and short-circuit output protection, as well a built-in
thermal cut-off - see Table 1: Ordering Information for voltage and power ratings.
Because the Ag8000 series is non-isolated the +VDC output is connected to the positive
input through a diode bridge.
