This signal should be optically coupled by the Host in order to maintain the requirements for the Vrms isolation. Stresses beyond those listed above may cause permanent damage to the device.

Exposure to absolute maximum rating conditions for extended periods may affect device reliability. It operates in a total stand-alone mode, with no need for user intervention. This PWM signal is filtered and utilized as the current limit circuitry voltage reference. 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.

Output port – The load resistance of the PD attached to the port is presented in parallel with R This disable-port pin can be controlled via the Host CPU.

Enables detection and powering of all Cisco devices including pre-standard terminals. The resulting voltage developed across both resistances is monitored to establish the Figure 1 shows the device with its related components for a 1-port configuration.

However, in order to reduce noise coupling, the grounds are physically separated and connected only at a single point. The digital and analog grounds are electrically the same ground. It allows the user cl21b104kabc choose a combination of three features, as specified in the following table: Line Detection Circuitry — when performing a line detection procedure, cl21b104bkac PoE device utilizes certain voltage levels over the output port.

In cases where the ambient temperature datasehet below C, or the product does not have to meet These levels are produced by switched resistor dividers and sensed by the PD in order to confirm a valid PD connection. The PD can operate over a wide temperature range: The CAP option is pre standard Capacitor detection mode.

The PD utilizes a dedicated pin, allowing an immediate disconnection of the PoE port. AC disconnect and DC disconnect function?

For a datashwet port, the system worst case power dissipation can be calculated as follows. Supports Back-off feature for Midspan implementation Including support for high power and 2-events classification. External Mosfet, increasing the flexibility of the solution and allowing it to be tailored for the power needs of the customer. The datasyeet are fixed for each mode of operation and described in the “R Mode pin” section in this document. The D15 and D16 should be selected for the application main voltage as follows: No additional voltage sources e.

This power must be isolated from the switch supply and chassis by Vrms. Grounds There are several grounds used in the system: Control A Reset control signal driven by the switch circuitry is used to reset the PoE cll21b104kbac. Visit our web site at: The Rsense in PD applications is only 1?
