PD69201 1-Port PSE PoE Manager Introduction Microchips PD69201 device is an IEEE 802.3af and IEEE 802.3at compliant single-port Power over Ethernet (PoE) Manager, used 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 Powered 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. Features Fully IEEE 802.3af and at compliant Continuous port and system data monitoring Includes two-event classification Power soft-start mechanism Supports pre-standard PD detection On-chip thermal protection Single DC voltage input (32 V57 V) Voltage monitoring and protection Wide temperature range: 40 C to 85 C Internal power-on reset Low thermal dissipation (internal 100 m sense RoHS compliant resistor) MSL1 2 I C communication Application Block Diagrams The PD69201 may be used in either an unmanaged standalone or a managed configuration.
