A four-port, mixed-signal, high-voltage PoE Manager. It enables network devices to share power and data over a single cable. 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 quad flat no-leads (QFN) package. PD69104B1 supports the following modes of operation: Microchip extended auto mode: A stand-alone mode in which the PD69104B1 detects IEEE 802.3af-2003 compliant powered devices (PDs) and IEEE 802.3at-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 communicate with PD69104B1 and configuring it. PD69104B1 executes all real-time functions as specified in IEEE 802.3AF-2003 (AF) and IEEE 802.3AT high power (AT) standards. This includes load detection, AF and AT classifications. In addition, the PD69104B1 device features Multiple Classification Attempts (MCA) port status monitoring. PD69104B1 supports detection of 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. PD69104B1/F supports supply voltages between 44V and 57V, with no need for additional power supply sources, and has built-in thermal protection. PD69104B1 is a low-power device that uses internal MOSFETs and external 0.36Ω sense resistors. PD69104B1 is available in a 48 lead, 8 mm × 8 mm QFN package.

  • Supports IEEE 802.3af and IEEE 802.3at, including two-event classifications
  • Microchip extended auto and semi auto
  • Supports pre-standard PD detection
  • Supports Cisco device detection
  • Single DC voltage input (44V to 57V)
  • Wide temperature range: –10°C to 85°C
  • Low-power dissipation (0.36O sense resistor)
  • Drives independent 4/2-pairs power port
  • Includes two selectable communication modes (I²C and UART)
  • Parameter setting using input pins or external serial EEPROM device
  • Built-in dynamic power management and emergency power management mechanisms with 3 x power supply power-good pins
