2 Quick Start

2.1 Input Power

2.1.1 Input Power (Labeled VPWR)

DC input voltage is provided through J1 (screw jack). A dc power supply with sufficient current capacity
can power the EVM.

Reverse voltage protection is not provided; ensure that the correct polarity is
applied to J1.

This dc input is labeled VPWR in the schematics and is used for port VBUS as well as for the TPS2388
device. The VPWR connections to the PoE ports are not fused. Each two pair port is capable of furnishing
at least 30 W and each four pair port can furnish 60 W.

The minimum PSE port voltage is 44 VDC for type 1 and 50 V for type 2. The nominal dc voltage at
VPWR is 48 VDC for a type 1 and 54 VDC for a type 2. During evaluation, choose the appropriate dc
power supply for the type 1 or type 2 environment.

2.1.2 Local 3.3 V (Labeled 3.3V)

Local 3.3 V for local devices (labeled as 3.3V) is provided by the onboard LM5019 buck converter. The
LM5019 provides a basic power-on sequence and provides a well-controlled and consistent startup. In
addition to 48 V, the TPS2388 requires 3.3 V for the digital circuitry and this is routed up to TPS2388EVM­016 over the connector interface.

2.1.3 External 3.3 V (Labeled 3.3V_USB)

The TPS2388EVM-612 provides galvanic isolation between PoE power side and host side using digital
isolators (ISO7241CD). The host side power is provided either from J2 (from USB2ANY) or J5 (from
LaunchPad). The current consumption is 6-mA typical, and 12-mA maximum.

Do not use USB2ANY and LaunchPad simultaneously.

CAUTION

2.2 PoE Port Interfaces

Configure the TPS2388 device with the host in order to get operational. Control the TPS2388 device
through the GUI or an external MCU. The host must configure the TPS2388 and send power on command
after a valid PD is connected to the port.

2.2.1 Standard 30 W, IEEE802.3 at Type 2 Ports

Four standard ports are provided at J19, J20, J8, and J7 for two-pair ports 1, 2, 3, and 4, respectively. The
power furnished is according to alternative A with MDI-X polarity.

2.2.2 Nonstandard 60-W Ports

Two non-standard, four-pair ports (J21 and J9) are provided. J21 is four pair port 1 and J9 is four pair port

2. The power furnished is according to alternative A with MDI-X polarity and alternative B on a single port
connector. A PD which can process power on all of the Ethernet conductors (refer to Dual TPS2378 PD

for 51-W High-Power Four-Pair PoE ) can power on and consume up to 60 W. A single PD can be

powered as well with proper operations (the Semi-Auto Mode reference code has the capability to power
on both single PD and dual PD). The Virtual Auto Mode reference code disables these high power ports
completely, since it is intended for use on IEEE802.3at compliant (2-pair) ports only.

2.3 I2C Interfaces

The EVM provides two I2C interfaces to the TPS2388.

2.3.1 USB2ANY

J2 provides an interface with the USB2ANY adapter when using a PC and GUI.

4 TPS2388EVM-612 Host Setup

4.1 MSP-EXP430G2 Setup

The TPS2388EVM-612 accepts the MSP-EXP430G2 evaluation module when the application requires
management of the TPS2388 devices with an external controller. Before inserting the MSP-EXP430G2
into the TPS2388EVM-612, make the following jumper changes and ensure that the target MSP430
(MSP430G2553) device is installed:

1. Remove the shunt on J5 in the P1.6 slot

2. Remove the shunts on J3 in the RXD and TXD slot. Re-install these in the vertical position as
described in MSP-EXP430G2 LaunchPad Development Kit

3. Install MSP-EXP430G2 onto TPS2388EVM-612 and ensure that the USB2ANY ribbon cable is not
installed into J2

4. Connect the PC to the LaunchPad as shown in Figure 2

5. The source code was developed for the MSP430 LaunchPad Development Kit (MSP-EXP430G2

http://www.ti.com/tool/msp-exp430g2) using the Code Composer Studio™ (CCS) version 7.1.0

(http://www.ti.com/tool/ccstudio-msp430) development environment. The target MSP430 can be
programmed within this environment. The reference code can be downloaded from the TPS2388
product folder on TI.com .

6. Once CCS is installed, use the basic set of instructions listed in Section 4.1.1 to import, build, and run
the project. CCS version 7.1.0 is used in the following examples. Note that a terminal program such as
HyperTerminal or Teraterm is required to view the output from the EVM when it is running.

www.ti.com

4.1.1 Basic CCS and Terminal Setup

1. Launch the CCS program on the PC: Start → Texas Instruments → Code Composer Studio 7.1.0 →
Code Composer Studio 7.1.0

2. OK the workspace location and CCS starts

3. Import the project: File → Import Existing CCS Eclipse Project

4. Navigate to the project location, then click the Finish button

5. Set the active project: Project, Build Configurations, Set Active, Virtual-Auto, or Semi-Auto

6. Build the project by clicking the hammer symbol

7. Launch debug session from CCS to activate the current project: Run, Debug (or F11).

8. Run the active project: Run, Resume (or play button, F8)

9. Determine the PC COM port connected to the LaunchPad by going into the Device Manager Ports
(COM and LPT) section. Launch the terminal program.

10. Once the terminal program is properly connected to the LaunchPad running the POE firmware, then
text similar to Figure 3 appears (If it does not appear at first, try to close Tera Term and reopen).

4.2 MSP430 Reference Code

4.2.1 Overview

There is a MSP40 reference code offered under the TPS2388 product folder on TI.com for basic
applications. Customers can download the code for free and develop their own system software starting
from here.

The system software supports the following features:

• Fully compliant to IEEE802.3at PoE specification

• Virtual Auto-Mode operation

• Device detection and classification

• DC disconnect

• Faults reporting

4.2.2 Semi-Auto Mode Reference code

The reference code can support PSE systems with up to 48 ports. It keeps track of all system level
parameters as well as port level parameters for each TPS2388 device within the system.

The main actions are interrupts triggered. As long as the MSP430 receives an interrupt signal from
TPS2388 devices, it checks the interrupt status and proceeds with related actions.

The system software also keeps track of system and devices error conditions that occur, as well as any
events that affect the port states. The MSP430 communicates with the PC through UART, reporting
parameters and status of the port.

TPS2388EVM-612 Host Setup

4.2.3 Virtual Auto Mode Reference Code

Since the TPS2388 does not have Auto Mode, the main purpose of Virtual Auto Mode reference code is to
operate the TPS2388 like Auto Mode by sending simple I2C commands. It is more beneficial to small PSE
systems with lower port count, since it does not need complex system control. For example, NVR
applications.

To enable the channel 5-8 for an 8 IEEE832.3at port system working in Virtual Auto Mode, you can go to
main_virtual_auto.c and add another loop with I2C address of channel 5-8.

!~The!~intent for 800ms delay is to provide sufficient time to allow the previous turn on commands to
complete before sending another (800ms per virtual “quad”). If there are 3 TPS2388 devices in the
system, the delay would be 400ms/3 = 133ms.

Figure 6. Semi-Auto Mode Reference Code Structure

CAUTION

The Virtual Auto Mode reference code disables channel 5–8 completely since it
is intended for use on IEEE802.3at compliant (2-pair) ports only. So nothing will
be powered on when you connect to the 4 pair ports.

EVM Schematic, Layout Guidelines and PCB Assembly, Layer Plots

5.2 Layout Guidelines

5.2.1 Supply Voltage Decoupling

Provide power supply pin bypass to the TPS2388 device as follows:

• 0.1 µF, 100 V, X7R ceramic at pin 28 (VPWR)

• 0.1 µF, 50 V, X7R ceramic at pin 1 (VDD)

5.2.2 Port Current Kelvin Sensing

KSENSA is shared between SEN1 and SEN2, while KSENSB is shared between SEN3 and SEN4. In
order to optimize the accuracy of the measurement, the PCB layout must be done carefully to minimize
the impact of PCB trace resistance. Refer to Figure 17 as an example.

5.2.3 Ground Plane Spacing and Isolation (GND, GND1, and EARTH nets)

Appropriate spacing should be provided between the GND, GND1, and EARTH nets as shown in

Figure 13.

5.3 PCB Drawings

Figure 11 through Figure 19 show the PCB layouts and assemblies for this EVM.
