DATASHEET

MAIN FEATURES DESCRIPTION

Description

Up to 12 PoE devices can be cascaded, fitting into a 96 port PoE system that

utilizes one PoE controller (PD69100)

The system supports three power management modes: Class (LLDP) mode,

Dynamic mode and Static mode. For more details see technical note 113, catalogue

number 06-0002-081.

Configure overvoltage and under-voltage thresholds for disconnection purposes.

PoE devices can be configured (both hardware and software) to enable higher

current through ports (up to ~720mA) or double power RJ in case of 4 pairs.

Supports both I2C and UART interfaces with Host CPU.

Enables detection and powering of pre-standard devices (PDs).

Direct SPI interface to an external LED stream circuitry. Enables designers to

implement a simple LED circuit that does not require a software code.

Digital output pin to Host, indicating voltage and temperature range are valid.

Measurements of the following parameters: Current (mA), Power Consumption (W),

Vmain (V), Port Voltage (V), PD Class (0-4).

Port statuses are received from PoE managers. Statuses such as ‘port on’ and ‘port

off due to disconnection or due to overload’

Interrupt out from PoE controller indicating events such as: port on, port off, port

fault, PoE device fault, voltage out of range, and more. For a full list of interrupt

events refer to Serial Communication Protocol, catalogue number 06-0032-056.

Configurable port power limit; when a port exceeds the limit, it is automatically

disconnected

Enables layout designers to connect all physical ports to logical ports whenever

required.

For systems comprising more than a single power supply, in case one power supply

fails, a fast port disconnection mechanism is executed to maintain operation and

prevent collapse of other power supplies.

I2C ADDRESS SELECTION

I2C interface between Host CPU and a specific PD69000 requires setting the device address; this is done by

applying a specific voltage level to pin #25 (I2C_ADDR) as shown below:

I2C_ADDR

VOLTAGE LEVEL

0.00 to 0.21VDC

0.21 to 0.41VDC

0.41 to 0.62VDC

0.62 to 0.83VDC

0.83 to 1.03VDC

1.03 to 1.24VDC

1.24 to 1.44VDC

1.44 to 1.65VDC

1.65 to 1.86VDC

1.86 to 2.06VDC

2.06 to 2.27VDC

2.27 to 2.48VDC
