Power Over Ethernet (PoE) is a technology that enables a single cable to carry both high-speed data and electrical power. It simplifies network deployments as it eliminates the need for a separate power source, making it possible to power a device from a platform rather than from an on-board power supply. This technology is widely applied in many different fields, from medical equipment and industrial Ethernet applications to wireless signal processing and communications.The PD81101EVB-15WB is a Power Over Ethernet (PoE) Controller, which is an integrated power management IC (PMIC) that enables communication with and power delivery to Ethernet-enabled devices allowing designs equipped with VoIP (Voice over Internet Protocol) systems, IP cameras and various Ethernet applications to reduce cost, board space, and power requirements.The PD81101EVB-15WB POE controller features a MOSFET implementation of the IEEE802.3af PoE standard, and can support circuit designs based on 15-20W of power. It provides support for four PoE ports or two PoE+ (PoE Plus) ports in order to support rapid adoption of new requirements.The PD81101EVB-15WB features an auxiliary core voltage regulator and a PMOS booster stage to provide a constant output up to 15W or 20W of power. The integrated circuit also has an input line monitor, a control loop and protection circuits to ensure that all IEEE 802.3af standards are met. The IC supports simple AC or DC power sources, eliminating the need for an external power supply.In addition, the IC provides power optimization and improved system multicasting capabilities, making it suitable for use in endpoints that require highly reliable system performance in demanding applications. The PD81101EVB-15WB also includes a programmable MPU interface that provides real-time information to system host applications running on the network.Overall, the PD81101EVB-15WB eliminates the need for expensive external components such as transformers, varistors, and PoE controllers when designing PoE-enabled endpoints. It provides high power up to 15w or 20W, robust safety features, a very wide operating range, and flexible configuration options in a very small package. The features and benefits of this new Power Over Ethernet Controller makes it ideal for a variety of applications, such as IP cameras, wireless access points, security systems, and industrial automation.
