Microchip PD69104B1ILQ-TR

控制器（PSE）36 W802.3at（PoE+），802.3af（PoE）

Overview

PD69104B1ILQ-TR is a four-port, Power over Ethernet (PoE) Manager. It enables network devices to share power and data over a single cable. The PD69104B1ILQ-TR 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 PD69104B1ILQ-TR device is a four-port, mixed-signal, high-voltage PoE Manager.The PD69104B, 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 PD69104B1F supports supply voltages between 44V and 57V with no need for additional power supply sources and has a built-in thermal protection. The PD69104B1ILQ-TR is a low power device that uses internal MOSFETs and external 0.36ohm sense resistors. The PD69104B1ILQ-TR is available in a 48 leads, 8 mm x 8 mm QFN package, and in two temperature range versions: PD69104B1FILQ (full industrial temperature range) and PD69104B1ILQ-TR (-10º to +85ºC)PD69104B1ILQ-TR modes of operation MSCC Extended Auto modeStand-alone mode in which the PD69104B1ILQ-TR 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 modeAllows the host to control which devices are powered and which are not, as well as to communicate with the PD69104B1ILQ-TR and to configure it.Auto modeAllows turning PDs on and off automatically. Used for systems with a full power supply. The PD69104B1F 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).MaximizeDownloadPartsTotal: 4Matching: 4ResetCompare PartsPart Status In Production Not Recommended for New DesignOperating Temperature[Min](°C)Package Type 48 QFN 8x8 Eval BoardPackage Carrier ESD Bag Tape & ReelPD-IM-7504BIn Production-Eval BoardESD BagPD-IM-7504B-SurgeIn Production-Eval BoardESD BagPD69104B1ILQ-TRIn Production-1048 QFN 8x8Tape & ReelPD69104B1FILQ-TRNot Recommended for New Design-4048 QFN 8x8Tape & ReelOrder Status Sales Contacts RFQ/SAMPLESContact SupportDocuments and ResourcesPackaging InformationProduct PortalsQualityReturnsTraining
