TPS2383B

www.ti.com

SLUS565G – JULY 2003 – REVISED AUGUST 2005

These devices have limited built-in ESD protection. The leads should be shorted together or the device

placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.

DESCRIPTION (CONTINUED)

The TPS2383B PSEPM can individually manage power for up to eight ethernet ports. All operations of the

TPS2383B are controlled through register read and write operations over a standard (slave) I

C serial interface.

The TPS2383B has dual SDA lines to allow easy application of opto-coupler circuitry to maintain ethernet port

isolation when a ground based controller is used. Each TPS2383B has five selection pins making it possible to

address up to 32 devices on the I

C bus and allows individual control and monitoring of up to 256 ethernet ports

from a single master I

C controller. Per-port write registers initiate and manipulate the flow of the discovery,

classification, and power-up states while the read registers contain status information of the enable process,

faults, classification value, and real time port operating current and voltage. Per-port status LED drivers are

provided which can be manually controlled through the serial I/O.

The TPS2383B is available in a full function 64-pin LQFP.

External N-channel MOSFETs switch port power. High-voltage (HV) gate drive ensures that these FETs are fully

enhanced, resulting in lower power dissipation and enabling the use of lower costs FETs. The TPS2383B

generates its HV gate supply from the 48-V port power, simplifying system power supply design. An external

3.3-V digital supply is also used. This supply can be active when 48-V power is not present which allows the user

to access the part through the serial I/O in this case. A 5-V analog supply is used to power port LEDs and

internal analog functions. Due to the very low quiescent current, both the 3.3-V and 5-V supply can be generated

from the 48-V power bus with minimal external components. An internal power-on-reset (POR) circuit with an

ORed external input pin resets all registers positions to a known safe state upon power up.

Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings

only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating

conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. All voltages

are with respect to GND. Currents are positive into and negative out of, the specified terminal.
