DESCRIPTION
KEY FEATURES
Microsemi's PD69101 is a single port, mixed-signal, high-voltage
Power over Ethernet driver. The device is utilized in Ethernet
switches and enables network devices to share power and data
over the same cable. It enables detection of IEEE802.3af-2003
compliant PDs (Powered Devices) and IEEE802.3at High Power
Devices, thus, ensuring safe power feeding and disconnection of
ports with full digital control and a minimum of external
components. Integrating power, analog and state of the art logic,
the PD69101 device fits into a single 24-pin, plastic QFN package.
A “plug and play” device, the PD69101 executes all real time
functions as specified in the IEEE802.3af-2003 (“AF”) and
IEEE802.3at High Power (“AT”) standards, including load detection,
“AF” and “AT” classification, and using Multiple Classification
Attempts (MCA).
The PD69101 :
Is designed to detect and disable disconnected ports,
utilizing DC disconnection methods, as specified in the
IEEE 802.3af-2003 and IEEE802.3ar-2009 standards.
Can optionally detect legacy/pre-standard PD devices.
Provides PD protection such as over-load, under-load,
over-voltage, over-temperature and short-circuiting.
Supports supply voltages ranging from 44 V to 57 VDC
with no need for additional power supply sources.
Is a low power device using an internal 0.3 MOSFET
and an external 0.5 sense resistor.
The chip includes built-in internal thermal protection.
Two LEDs provide port state's indication and port type (AF/AT).
