NOTES:

Chapter 1. Product Overview

1.1 INTRODUCTION

This chapter provides an overview of the EMC1833 Evaluation Board:

• What is the EMC1833 Device?
• What is the EMC1833 Evaluation Board?
• What the EMC1833 Evaluation Board Kit Contains

1.2 EMC1833 DEVICE OVERVIEW

The EMC1833 Evaluation Board is used to evaluate the EMC18XX family of remote diode temperature monitors. Users can now easily evaluate many of the integrated features of the EMC18XX device family. The device also has a on-board connector configured for an anti-parallel diode to allow for off-board temperature measurements. In addition, the evaluation board connects to PC through a USB interface. Temperature can be data-logged using the Microchip Thermal Management Software Graphical User Interface (GUI).

1.3 EMC1833 EVALUATION BOARD OVERVIEW

The board enables users to easily evaluate many custom programmable features such as Rate of Change, Temperature Alert Limit settings, Temperature Conversion Rate, Resistance Error Correction (REC) and Power Modes.

Figure 1-1 shows the top view of the EMC1833 Evaluation Board.

1.4 EVALUATION BOARD KIT CONTENTS

The EMC1833 Evaluation Board Kit includes:

• EMC1833 Evaluation Board (ADM00773)
- USB cable
• 2N3904FS-ND transistor (TO-92 package)
- Important Information Sheet

Chapter 2. Installation and Operation

2.1 GETTING STARTED

This section describes how to power-up and interface with the EMC1833 Evaluation Board. Items discussed in this chapter include:

• System and configuration requirements
• The hardware setup required prior to using the evaluation board
  • Performing software setup
• Operating the device's software interface, the Thermal Management Utility - [EMC1833] GUI.

2.2 SYSTEM AND CONFIGURATION REQUIREMENTS

The EMC1833 Evaluation Board is designed to be used in a Microsoft Windows® XP® (SP3 or later) environment, based on the Microsoft.NETTM Framework 2. Users can utilize the Microsoft .NET Framework 2 web installer package to download and install the .NET Framework components. For USB connectivity, the minimal physical requirement for the PC is a standard USB 2.0 port. In case the board connects to the PC through a USB hub, use a self-powered hub.

2.3 BOARD SETUP

Before the EMC1833 Evaluation Board can be used, a few steps must be performed to install the PC software and configure the board's hardware.

1. Download the support material (PC application) that can be found on the ADM00773 board page, at www.microchip.com. Unzip the archive and install the .exe file.
2. Connect the collector and base of the transistor to the DP input and the emitter to the DN input. The orientation of the transistor is shown below. Note the transistor is flat side down, as you can observe in Figure 2-1.

FIGURE 2-1: Board Connections.

2.3.1 Hardware Setup and Description

Follow these steps to set up the hardware:

1. The board has a mini-USB connector for a PC interface. Connect the USB cable from the evaluation board to a PC.
2. Start the Thermal Management Software GUI for temperature data logging or to evaluate the sensor board features.

This evaluation board is fully powered from PC USB source, 5V. Once power is applied via USB, and the USB is successfully enumerated then the PIC ^® microcontroller is ready to receive commands from the host PC to program the EMC1833 settings or transfer temperature data.

FIGURE 2-2: EMC1833 Evaluation Board Circuit Block Diagram.

The block diagram in Figure 2-2 shows that the EMC1833 device is able to monitor and report the ambient temperature of two external diode-connected transistors. One diode is installed on the PCB. A two-pin connector allows the user to connect an additional transistor for evaluation of off-board temperature applications. The Alert outputs, SDA, SCK, and VDD are connected to test points for external connections; in addition, these outputs are also connected to the microcontroller I/O pins so that the Alert Output statuses can be detected in software.

Chapter 3. Software GUI Description

3.1 THERMAL MANAGEMENT UTILITY SOFTWARE GUI OVERVIEW

The Microchip Thermal Management Software GUI allows users to evaluate the EMC1833 for temperature sensing applications. Once the hardware is connected, the software recognizes the device ID and displays the corresponding GUI for the evaluation board. Disconnecting the USB will close the GUI. This tool enables users to evaluate the sensor features and perform temperature data-log. Figure 3-1 depicts the Thermal Management Utility GUI.

As displayed in Figure 3-1, the GUI can be divided into three sections:

1. One Shot action buttons
2. Temperatures, Sensor Settings and Registers List tabs
3. Data Acquisition Charting area

3.2 REAL-TIME ACQUISITION ACTION BUTTONS

The Play, Stop, and Reset icons (Figure 3-2) can be used to perform continuous data acquisitions.

To stop the data logging click the Stop Recording button. Users can now go to the file location to view the file.

3.3 TEMPERATURES, SENSOR SETTINGS AND REGISTERS LIST TABS

3.3.1 Temperatures Tab

The Temperatures tab displayed in Figure 3-4 shows the results of the Internal Diode 1 and Diode 2 sensors. This tab also displays the result of the various user programmable features of the EMC1833, such as the temperature ALERT and THERM status, Diode Fault status, the Rate of Change (ROC), and hottest diode comparison.

FIGURE 3-4: Temperatures Tab.

3.3.2 Sensor Settings Tab

The Sensor Settings tab is divided into two sections:

• General Settings
• Rate of Change

Figure 3-5 displays the General Settings section under the Sensor Settings tab. This is where the user configures and enables/disables various features of the device.

Refer to the MCP1812/13/14/15/33 data sheet for detailed information on the operation of these features and settings.

FIGURE 3-5: Sensor Settings Tab - General Settings.

Figure 3-6 displays the Rate of Change (ROC) section under the Sensor Settings tab. This is where the user configures the ROC feature. Refer to the MCP1812/13/14/15/33 data sheet for detailed information regarding the ROC setup and operation.

Rate of Change General Settings Temperature Rate of Change Settings Enable ROC Hysteresis (C) 0 Channel 1 Gain 1 Samples 2 Limit (C) 0

FIGURE 3-6: Rate of Change Tab.

Since the software is constantly polling the status register the status bits are cleared as soon as an out of bounds condition is satisfied when in the Interrupt mode.

A quick way to validate the ROC is utilizing the Standby mode along with the one-shot temperature measurement.

ROC validation example:

1. Select Standby mode.
2. Set the Gain and Samples drop downs.
3. Select the Enable ROC check box.
4. Click one-shot.
5. Update registers and log temperature for Remote Diode 1.
6. Repeat steps 4 and 5 for the samples selected (when all samples have completed the ROC result value will update).
7. Calculate the ROC result using Equation 3-1 and compare to the calculated value in the ROC result within the GUI.

EQUATION 3-1:

$$ \frac {\Delta \mathrm{T}}{\Delta \mathrm{t}} \frac {[ \mathrm{T} (\mathrm{t} _ {\max}) - (\mathrm{T}) ] \yen \text {gain}}{\text {sample 1 - (}} $$

Where:

$$ \begin{array}{l} T \left(T _ {T \max}\right) = \text { Temperature at the end of the interval }. \ T (t _ {0}) = \text { Temperature at the beginning of the interval. } \ \end{array} $$

3.3.3 Registers List Tab

The Registers List tab (Figure 3-7) contains a read-only table that contains all the user registers.
