Microchip’s PD69201 device is an IEEE® 802.3af and IEEE 802.3at compliant single-port Power over Ethernet (PoE) Manager for use in Ethernet switches to allow network devices to share power and data over the same cable. With minimal external components, the PD69201 supports both IEEE 802.3af/at and Legacy Power Devices (PDs). Integrating power, analog, and state-of-the-art logic, the PD69201 is available in a 10-pin, 3 mm × 4 mm DFN package.

The PoE manager IC integrates power, analog, and state-of-the-art logic into a single 56-pin, plastic QFN package. The device is used in Ethernet switches and midspans to allow network devices to share power and data over the same cable. The PD69208T4 device is an 8-port, mixed-signal, and high-voltage PoE driver. Together with the PD692x0 external MCU, it performs as a PSE system. The PoE controller, PD692x0, is a cost-effective, pre-programmed MCU designed to implement enhanced mode PoE. PD69208T4 supports supply voltages between 32V and 57V without additional power supply sources. A system that powers over four pairs can be implemented by combining two ports of PD69208M, enabling a high-power delivery to compatible PD devices. An on-going monitoring of system parameters for the host software is available via communication. Internal thermal protection is implemented in the chip. PD69208T4 is a low-power dissipation device that uses internal MOSFETs and internal 0.1Ω sense resistors. PD69208T4 is available in a 56 pin, 8 mm x 8 mm QFN package.

PD69210 is a Microchip-based cost-effective, pre-programmed MCU designed to implement Enhanced mode PoE control in conjunction with the PD69208M, PD69208T4 and PD69204T4 PSE Managers. The PD69210 features an ESPI bus connection up to 12 PSE Managers. PD69210 features an ESPI bus interface up to 12 PoE managers. PD692x0 has an embedded ARM Cortex™-M0+ core. It also uses I2C or UART interface to the host CPU and is designed to support software field upgradable through the communication interface. The PD69210 utilizes I2C or UART interface to the host CPU. PD69210 is available in 32 pin, 5 mm x 5 mm QFN package.

The PD70101 is an integrated Powered Device (PD) Interface and PWM controllers for a DC-DC converter used in IEEE 802.3af applications. The PD70101 can be used for IEEE 802.3af Type 1 applications. The device has several features designed to improve efficiency and reliability: * Capacitor * Gate drivers * Peak current mode control * Maximum duty cycle * Soft-start circuit * Low voltage protection warning and monitoring Start your PoE PD power supply design using [Microchip MPLAB® Analog Designer](https://mad.microchip.com/poe).

The PD70200 device is a part of Microchip’s series of Power over Ethernet (PoE) Powered Devices (PDs). The device transmits integrated power and analog data in a single 12-pin package. It is used in PDs, thus enabling next generation network devices to share power and data over the same cable. Microchip’s new PD family offers a solution to any PD application compliant with IEEE 802.3af and IEEE 802.3at standards and 4-pairs extra power applications. The IC family’s components can be used in both indoor and outdoor applications. The device family meets all PD-side-standards such as: * Detection classification * Integrated isolation switch with inrush current limiter, and over-current protection * Two-events classification recognition and AT flag generation In addition, the devices have a discharge mechanism for a DC / DC input capacitor, ensuring quick redetection capability in case the RJ-45 plug is disconnected and reconnected within a short time span. The PD70200 IC design specifically supports IEEE 802.3at Type 2 standard, including two events classification detection that enables the PD to distinguish whether the connected power source equipment (PSE) is IEEE 802.3at or IEEE 802.3af based. The PD70200 IC is designed to support 4 pair applications for PDs that require higher power.

The PD70210A device is an advanced PD interface controller (front-end IC) for powered devices in PoE applications. It supports IEEE 802.3af, IEEE 802at, HDBaseT, and general 2- pair or 4-pair configurations. The PD70210 device includes an advanced classification block that supports 2, 3, 4, and 6 event classification. Using the SUPP\_Sx pins, they also identify which of the four pairs of the cable receive power and generates appropriate flags. The IC features an internal bleeder for rapidly discharging the input capacitor of the DC–DC converter, to ensure fast re-detection and port power-up in case of sudden removal and re-insertion of the Ethernet cable into RJ-45.
