PD69008 - 8 Ports Power Over Ethernet Manager Description _________________ Microsemi’s PD69008 Power over Ethernet (PoE) Manager chip integrates power, analog and state of the art embedded core logic into a single 80-pin, plastic QFP package. The device is used in Ethernet switches and Midspans to enable network devices to share power and data over the same cable. PD69008 device is an 8-port, mixed-signal, highvoltage Power over Ethernet driver. 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 via a serial communication interface and a minimum of external components, the device integrates into multiport and highly populated Ethernet switches and routers. The PD69008 executes all real time functions as specified in the IEEE802.3af-2003 (“AF”) standard and IEEE802.3at High Power (“AT”) functionality, including load detection, “AF” and “AT” classification and port status monitoring. In addition it performs system level activities such as power management and MIB support for system management. The PoE device is designed to detect and disable disconnected ports, utilizing both DC and AC disconnection methods, as specified in the IEEE 802.3af-2003 standard. The PD69008 is designed to support 2 main configurations: • Auto mode: For Basic ”AF” and “AT” PSE equipment • Enhanced mode: For High End, Extended features set of AF and AT PSE equipment Port_neg0 Sense_Neg 61 port_sense0 AGND2 62 64 1 60 LSC/ GPIO3 Vport_pos1 2 59 Vport_pos2 3 58 LSD/ GPIO2 CS_EEPROM_n/ LSL / Interrupt_n Vport_pos3 4 57 Vperi Vport_pos4 5 56 Ext_reg Vport_pos5 6 55 ADC2p5 Vport_pos6 7 54 QGND Vport_pos7 8 53 I2CINI NC 9 52 Vcc2p5 NC 10 51 ASIC_INI NC 11 50 Iref NC 12 SDA SDA_out / Test_mode 15 46 SCL 16 DGND2 17 Good0/GPIO0 18 Good1/GPIO1 19 Date Code 45 SCK 44 MOSI 43 42 41 ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ I2C or UART Host interface Serial communication protocol backwards compatible with PD63000 and PDIC66000 Added monitoring Extended parameters setting Port matrix for flexible PCB Layout Field upgradeable software Emergency Power Management with four power supplies Ordering Information __________ Part number MISO CS_n Disable_ports_n 40 DGND1 38 39 NC NC 37 35 36 NC NC NC 34 NC 32 33 NC NC 31 NC 30 NC 29 NC 28 NC 27 Port_neg7 26 24 25 gate_7 gate_6 port_sense7 22 23 port_sense6 AGND1 Port_neg6 21 20 Copyright © 2009 Rev. 1.0, 2009-03-15 ♦ ♦ ♦ ♦ ♦ ♦ ♦ Fully IEEE802.3af-2003 compliant Designed to support IEEE802.3at including twoevent classification Supports pre-standard PD detection Supports Cisco devices detection IETF Power Ethernet MIB (RFC 3621) compliant Single DC voltage input (44v-57v) Wide temperature range: -40° C to +85° C Low thermal dissipation (0.5Ω sense resistor) Drives 8 independent two-pairs power ports or 64-pairs ports Can cascade up to 8 PoE devices (64 ports) EEPROM interface for software patching and parameter configuration I2C Host interface Supports Interrupt out pin Dynamic power management Emergency power management supporting three configurable Power Bank I/Os Direct register communication Direct LED drive supporting one or two colors Continuous monitoring per port and system data Parameter setting per port and per system Power soft start algorithm Thermal monitoring/protection Voltage monitoring/protection H/W disable ports input Built in 3.3 V regulator Internal power on reset Enhanced SPI bus for internal communication External EEPROM for system parameters update SW ROM patch option RoHS compliant Reset_n 47 Ref_port_neg rGood2/GPIO4 49 14 13 Vmain PD69008 48 CP_IN ♦ ♦ ♦ ♦ Vport_pos0 CP_OUT PD69008 Auto Mode features: Enhanced Modes Additional Features: 63 gate_1 gate_0 65 port_sense1 66 Port_neg2 Port_neg1 67 73 69 68 port_sense3 74 70 Port_neg3 75 gate_3 Port_neg4 76 port_sense2 port_sense4 77 gate_2 gate_4 78 71 gate_5 79 72 Port_neg5 port_sense5 80 Pin Configuration _____________ Supported Features __________ PD69008 Temperature range -40 to 85°C Package LQFP 80 pin This datasheet refers to ICs with date code "XAA0843" or later.

Loads that dissipate more than Icut for longer than Tcut are classified as ‘overloads’ and are automatically shutdown. Loads that consume Ilim current for more than Tlim are shutdown and classified as 'short circuit state'. In cases where the PD69008 is configured to operate in DC-Disconnect mode, and the output current is below Imin for more than Tmin , the PD is classified as ‘no-load’ and is shutdown. In cases where the PD69008 is configured to operate in AC-Disconnect mode, and the load's impedance is above a pre-defined impedance for more than Tmin, the PD is classified as ‘no-load’ and is shutdown. Automatic recovery from overload and no-load conditions is attempted every period of TOVLREC and TUDLREC (typically 5 and 1 seconds, respectively). Output power is limited to Ilim, which is a maximum peak current allowed at the port.

Examples of such applications are described below: Integrated directly into a switch: Facilitates entire PoE concept by including the IC(s) on the main switch’s PCB. Daughter board add-on: The IC is integrated into a small dedicated PoE PCB, mounted on top of the switch’s main PCB or into a DIMM module. Integrated into an RJ45 connector: Saves space on the main board and creates small differences between the PoE and non-PoE versions of a switch. Midspans: Stand-alone devices, installed between the Ethernet switch and the PDs (Powered Devices) such as telephones, cameras, wireless LANs, etc. These Midspans include the PD69008 IC as a PoE control element, destined to inject power over the communication lines.
