PMIC - Power Over Ethernet (PoE) Controllers are devices used to regulate the amount of electricity supplied to Ethernet (Ethernet) components through the network connection. They ensure that only the correct amount of power is used, and this ensures that the system maintains proper functionality and optimal efficiency. One such device is the PD69101ILQ-TR. This device is specifically designed to be used in a Power Over Ethernet (PoE) network.

The PD69101ILQ-TR is an integrated 4-channel by 8-channel Power Over Ethernet (PoE) controller that meets the 802.3af PoE standard. It is used in Power Sourcing Equipment (PSE) such as bridges, access points, and routers, and it since it has both a DC-DC converter and a variable output current regulator, it can provide both power and control to the network infrastructure. It supports a wide input voltage range from 36V to 57V, and its four output channels are capable of providing up to 30W of power each.

In addition to its primary function of regulating the power output of PoE devices, the PD69101ILQ-TR also provides several secondary features. It can detect the presence of active Ethernet devices and signal the data signal rate of each connected device. It also features an integrated overvoltage protection (OVP) circuit for protecting against potential damage to equipment caused by power surges. It also contains a fault monitoring circuit that detect faults on the output, and will shut off power if the system exceeds its regulated levels.

The working principle of the PD69101ILQ-TR is relatively simple. It uses a switching system to control the output current, and this is controlled by a dedicated control logic block. The logic block overseas the input and output of the controller, and once it has determined the amount of current needed, it will switch the output to deliver the desired current. This is done in order to ensure that the system is both safe and efficient, and can also adjust the voltage and current levels to keep them within the limits set by the 802.3af PoE standard.

Overall, the PD69101ILQ-TR is an integral part of any PoE network, as it ensures that the system is both efficient and safe. It regulates the amount of power delivered to the network components, and also features several features designed to protect against potential damage caused by power surges. Additionally, its integrated OVP circuit and fault monitoring circuit are essential for keeping the system running properly. As a result, the PD69101ILQ-TR is an ideal option for any Power Over Ethernet (PoE) network.
