Power Over Ethernet (PoE) Controllers are power management integrated circuits (PMICs) that are examples of power management solutions for applications requiring the delivery of electrical power over LAN cables. These solutions help to provide power to a range of devices, including IP phones, webcams, wireless access points and networked surveillance cameras. The PD70210AILD-TR is a PoE controller designed to offer a flexible and cost-effective solution for PoE systems with output current up to 9000mA, though not exceeding the IEEE 802.3af maximum of 700mA.

The PD70210AILD-TR is an integrated circuit which contains an output controller circuit, a switching controller, an over-current protection (OCP) circuit, two voltage references, two on/off control pins and an output power limitation circuit. The input voltage range for the device is from 24.5V to 57V and the output current can be adjusted based on the size of the power supply. The output current is further enhanced by the integrated OCP circuit which enables the controller to detect an output over-current condition and cut off the output current to prevent damage to the system components.

The PD70210AILD-TR is well-suited for Ethernet applications. It provides a solution to meet the increasing demand for power over Ethernet networks. The device is DC input compatible and it provides high output power and efficiency. The output voltage is adjustable by controlling the duty cycle of the internal switching controller, which is regulated by the voltage reference circuit. The on/off control pins can be used to enable/disable the output and reduce the standby current. The device provides over-temperature protection, over-voltage protection and short-circuit protection.

When used as part of a PoE system, the PD70210AILD-TR is designed to provide a power management solution that is compliant with the IEEE 802.3af specification. The device is optimized for use with line-powered PoE midspans such as the NLII ON-U series and it is compliant with the two-event classification (TEC) signaling protocol used by the ON-U series. This ensures that the device can detect a valid PoE connection request from the device.

The PD70210AILD-TR is an ideal solution for applications that require the delivery of electrical power over Ethernet cables. It offers a flexible and cost-effective PoE solution for systems with output current up to 9000mA, while maintaining in compliance with IEEE 802.3af specifications. The device is designed to deliver reliable power management solutions with over-current and over-temperature protection, as well as short-circuit protection.
