For a single port, the system worst case power dissipation can be calculated as follows. No additional voltage sources e. The PD has a very low thermal dissipation. In cases where the ambient temperature drops below C, or the product does not have to meet This power must be isolated from the switch supply and chassis by Vrms. Classification Circuitry — After a port is investigated, the PD should be classified by a classification current signature.

Line Detection Circuitry — when performing a line detection procedure, the PoE device utilizes certain voltage levels over the output port.

The D15 and D16 should be selected for the application main voltage as follows: Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

Visit our web site at: This ground plane should be Vrms isolated from the PoE circuitry as well as the power supply for the PoE circuitry. Cl211b04kbac detection and powering of pre-standard power devices PDs. It operates in a total stand-alone mode, with no need for user intervention. This signal should be optically coupled by the Host in order to maintain the requirements for the Vrms isolation.

Control A Reset control signal driven by the switch circuitry is used to reset the PoE circuit. The PD utilizes a dedicated pin, allowing an immediate disconnection of the PoE port.

This PWM signal is filtered and utilized as the current limit circuitry voltage reference. Grounds There are several grounds used in the system: External Mosfet, increasing the flexibility of the solution and allowing it to be tailored for the power needs of the customer. Each PD device handles one port.

If an adequate 5V power source is available, the 5V regulation circuitry can be removed and the zener diodes may be replaced by lower current 5mA zener diodes but with same voltage requirements. These levels are produced by switched resistor dividers and sensed by the PD in order to confirm a valid PD connection. The values are fixed for each mode of operation and described in the “R Mode pin” section in this document.

AC disconnect and DC disconnect function? The digital and analog grounds are electrically the same ground. However, in order to reduce noise coupling, the grounds are physically separated and connected only at a single point.

Multi — point resistor detection? Stresses beyond those listed above may cause cl21b104kbzc damage to the device. The PD can operate over a wide temperature range: Output port – The load resistance of the PD attached to the port is presented in parallel with R It allows the user to choose a combination of three features, as specified in the following table: Enables datashete and powering of all Cisco devices including pre-standard terminals.

The Rsense in PD applications is only 1? The PD requires a single DC voltage source: The CAP option is pre standard Capacitor detection mode. This disable-port pin can be controlled via the Host CPU.

Figure 1 shows the device with its related components for a 1-port configuration. The resulting voltage developed across both resistances is monitored to establish the With a minimum of external components, the PD integrates in a one-port or two- port PoE-port switches and Midspans.

Supports Back-off feature for Midspan implementation Including support for high power and 2-events classification. Direct driving of the LED circuitry.
