Pin Description
1 |
VIN+
|
POE Direct Input +. This pin connects to the positive (+) output of the POE input bridge rectifiers. |
2 |
VIN-
|
POE Direct Input -. This pin connects to the negative (-) output of the POE input bridge rectifiers. |
3 |
AT Detect Output |
AT Detect Output. This pin indicates if an IEEE802.3at PSE is supplying power to the DP5400; |
4 |
NC |
Internal Connection. Do not connect to this pin. |
5 |
-VDC
|
Negative DC Output. This pin provides the negative regulated output from the Ag5300 and is internally connected to pin 8. |
6 |
+VDC
|
Positive DC Output. This pin provides the positive regulated output from the DP5300. |
7 |
ADJ
|
Output Adjust. The output voltage can be adjusted from its nominal value, by connecting an external resistor from this pin to either the +VDC pin or the -VDC pin. |
8 |
-VDC
|
Negative DC Output. This pin provides the negative regulated output from the Ag5300 and is internally connected to pin 5. |
