描述 Description

Microsemi’s PD69104B1 Power over Ethernet (PoE) Manager enables network devices to share power and data over a single cable. The PD69104B1 PoE Manager chip is employed by both Ethernet switches and Midspans. The device integrates power, analog circuitry and state of the art control logic into a single 48-pin plastic QFN package. The PD69104B1 device is a 4 port, mixed-signal, high-voltage PoE Manager. The PD69104B1 supports 3 modes of operation: MSCC Extended Auto mode – this is a stand-alone mode in which the PD69104B1 detects IEEE802.3af-2003 compliant PDs (Powered Devices) and IEEE802.3at-2009 High Power devices, ensuring safe power feeding and disconnection of ports based on a power management algorithm while employing a minimum of external components. Semi Auto mode – allows the host to control which devices are powered and which are not, as well as to communicate with the PD69104B1 and to configure it Auto mode – allows turning PDs on and off automatically. Used for systems with a full power supply. The PD69104B1 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\" classifications, and using Multiple Classification Attempts (MCA). The PD69104B1, supports detect legacy/pre-standard PD devices. It also provides PD real-time protection through the following mechanisms: overload, under-load, over-voltage, over-temperature, and short-circuit. The PD69104B1 supports supply voltages between 44V and 57V with no need for additional power supply sources and has a built-in thermal protection. The PD69104B1 is a low power device that uses internal MOSFETs and external 0.36ohm sense resistors. The PD69104B1 is available in a 48 leads, 8 mm x 8 mm QFN package.  ROHS, PB Free
