A power management integrated circuit (PMIC) is an important part of any system-level design. PMICs are integrated circuits that provide power management and control for systems, embedded processors, and other components. Specifically, PMICs are used to provide power conversion, voltage scaling, and power conditioning, as well as circuit protection, monitoring, and interfacing with other power management systems. The Power over Ethernet (PoE) controllers are a type of PMIC used to control the flow of power over Ethernet cables. One such PoE controller is the PD81101EVB-21WT.

The PD81101EVB-21WT is a power-over-Ethernet (PoE) controller with a wide operating temperature range of -40 to 85°C. The PD81101EVB-21WT is capable of supplying up to 21W of continuous power to up to four RJ45 ports over standard Ethernet cables. The controller has an integrated digital signal processor (DSP) with four 12-bit A/D converters and a 10-bit D/A converter, which enables it to accurately measure and manage power in power over Ethernet polynomial applications including IP cameras, IP phones, VoIP systems, and PoE switches and hubs. The PD81101EVB-21WT is designed to provide efficient and reliable power delivery, integrated fault protection and monitoring, and EMI protection.

The PD81101EVB-21WT is designed to provide an efficient, reliable and scalable PoE solution for applications such as IP cameras, IP phones and VoIP systems. The controller supports the Power Over Ethernet industry standard IEEE 802.3af and can supply up to 15.4W of power to the ports. The controller includes an advanced DSP to measure current, voltage and temperature for accurate control of the power delivery. Additionally, the PD81101EVB-21WT includes a variety of integrated fault protection and monitoring functions as well as EMC protection. This makes the PD81101EVB-21WT a great solution for PoE applications.

The PD81101EVB-21WT employs a digital signal processor-based control strategy for its power control. In this control strategy, the DSP functions as the core of the power management system and is responsible for monitoring system parameters such as current, voltage, and temperature. Based on these inputs, the DSP will adjust voltage levels and other parameters to ensure reliable, stable power delivery. Additionally, the PD81101EVB-21WT has a number of integrated protection features designed to protect against faults in the system. These protection features include independent over-current protection, under-voltage protection, thermal shutdown protection and over-temperature protection.

The PD81101EVB-21WT is a robust, reliable, and efficient PoE controller with a wide operating temperature range and an integrated power conversion, voltage scaling and power conditioning system. The controller provides accurate current and voltage measurement as well as monitoring capabilities. Additionally, the controller is designed with an extensive array of protection features to safeguard the system against potential faults. The PD81101EVB-21WT is an ideal solution for a variety of PoE applications.
