High-Side Configuration

4. Quick Start Procedures

1. Apply VS = 3.3V input power supply (3V < VS < 5.5V) to VS and GND terminals. 2. Apply 12V input power voltage (0V < IN+ < 32V) to the IN+ and GND terminals. 3. The default sense resistance is 100mΩ. 4. Connect an external load to the IN- and GND terminals, and keep loading current = 0.5A. 5. Measure the sense voltage (approximately 50mV) between the IN+ and IN-. 6. Use the RTQ6059 GUI to check practical sense voltage, bus voltage, current, and power.

8. IN+ and IN- Input RC Filter

The RTQ6059 Evaluation Board features an RC filter option to shield the IN+ and IN- inputs from high-frequency noise. As depicted in Figure 3, the default settings are 0Ω for resistance and 0.1µF for capacitance. <a class="fancybox" href="/content/dam/richtek-eds/resources/evaluation-boards/evb_rtq6059gj8/html-images/image004_en.png"><img border="0" width="378" height="254" src="/content/dam/richtek-eds/resources/evaluation-boards/evb_rtq6059gj8/html-images/image004_en.png" alt="Technical Document Image Preview" /></a> Figure 3. Input Filter Setting

9. Freely Choose between High-Side or Low-Side

Figure 1 shows the RTQ6059 Evaluation Board in a high-side configuration. To switch to a low-side configuration, as per Figure 4, short the VIN- pin to GND, connect VIN+ to Load +, connect Load - to PSU2 +, and short PSU2 to GND. According to the design architecture, Low-Side Configuration is only suitable for current measurement. This configuration method involves connecting the measurement device between the load and the ground, allowing for the direct measurement of the current passing through the load. <a class="fancybox" href="/content/dam/richtek-eds/resources/evaluation-boards/evb_rtq6059gj8/html-images/image005_en.png"><img border="0" width="567" height="194" src="/content/dam/richtek-eds/resources/evaluation-boards/evb_rtq6059gj8/html-images/image005_en.png" alt="Technical Document Image Preview" /></a> Figure 4.

12. Graphical User Interface Overview

The RTQ6059 Evaluation Board includes the RTQ6059 CSOP GUI, which allows users to control the RTQ6059. Figure 19 displays the GUI interface, which is user-friendly. <a class="fancybox" href="/content/dam/richtek-eds/resources/evaluation-boards/evb_rtq6059gj8/html-images/image020_en.png"><img border="0" width="497" height="454" src="/content/dam/richtek-eds/resources/evaluation-boards/evb_rtq6059gj8/html-images/image020_en.png" alt="Technical Document Image Preview" /></a> Figure 19. RTQ6059 Graphical User Interface

13. Quick Operation of the RTQ6059 EVB Software

Step 1. Check Slave Address. Step 2. Set Configure Operation Mode. Step 3. Set Conversion Time. Step 4. Set the shunt resistor value. Step 5. Set Max expected current for sensing. Step 6. Set min current resolution for current LSB. Step 7. Push “Apply” bottom, the 0x05 Calibration register is written into a value for expected current LSB. Step 8. The data of single read or continued read selection.

14. Selection of Slave Address

Slave Address is follow Figure 20. Users can connect multiple EVBs and upon clicking the "Refresh" button, the GUI will detect all connected slave addresses. <a class="fancybox" href="/content/dam/richtek-eds/resources/evaluation-boards/evb_rtq6059gj8/html-images/image021_en.png"><img border="0" width="456" height="394" id="圖片 2" src="/content/dam/richtek-eds/resources/evaluation-boards/evb_rtq6059gj8/html-images/image021_en.png" alt="Technical Document Image Preview" /></a> Figure 20. Select Slave Address

15. Customize the Configuration Operation

This GUI provides configuration options for operations such as setting the Bus Voltage Range, PGA Range, and Operating Mode, as illustrated in Figure 21. Users can decide on all the modes to be set based on their own needs. <a class="fancybox" href="/content/dam/richtek-eds/resources/evaluation-boards/evb_rtq6059gj8/html-images/image022_en.png"><img border="0" width="566" height="339" src="/content/dam/richtek-eds/resources/evaluation-boards/evb_rtq6059gj8/html-images/image022_en.png" alt="Technical Document Image Preview" /></a> Figure21. Configure Operation

16. Conversion Time Settings

Users can customize the required conversion times as shown in Figure 22. Both Bus and Shunt settings are configured independently. To observe differences, selecting longer conversion times is advisable. <a class="fancybox" href="/content/dam/richtek-eds/resources/evaluation-boards/evb_rtq6059gj8/html-images/image023_en.png"><img border="0" width="548" height="173" src="/content/dam/richtek-eds/resources/evaluation-boards/evb_rtq6059gj8/html-images/image023_en.png" alt="Technical Document Image Preview" /></a> Figure22. Bus/Shunt Conversion Time Settings

17. Auto Calibration Function

Users need to correctly configure the compensation values in the Configuration Register to ensure accurate readings are displayed in the software. Setting the correct compensation values requires the following Equation 1, which can be cumbersome for users. Therefore, the GUI provides an automatic compensation calculation method. As shown in Figure 23, by entering the resistance value used, the maximum current, and the minimum current LSB, the final required compensation value can be calculated. <a class="fancybox" href="/content/dam/richtek-eds/resources/evaluation-boards/evb_rtq6059gj8/html-images/image024_en.jpg"><img border="0" width="378" height="56" src="/content/dam/richtek-eds/resources/evaluation-boards/evb_rtq6059gj8/html-images/image024_en.jpg" alt="一張含有文字, 字型, 白色, 螢幕擷取畫面的圖片自動產生的描述" /></a>……………………………….(1) <a class="fancybox" href="/content/dam/richtek-eds/resources/evaluation-boards/evb_rtq6059gj8/html-images/image025_en.png"><img border="0" width="252" height="211" id="圖片 27" src="/content/dam/richtek-eds/resources/evaluation-boards/evb_rtq6059gj8/html-images/image025_en.png" alt="一張含有文字, 螢幕擷取畫面, 陳列, 字型的圖片自動產生的描述" /></a> Figure 23.

18. Function for Drawing Chart

Figure 24 displays the process when the "Auto Read" button is pressed, depicting the wait for the GUI to capture data. Figure 25 shows that users can select the desired ranges to plot and check them, with the results being immediately displayed on the Graph. <a class="fancybox" href="/content/dam/richtek-eds/resources/evaluation-boards/evb_rtq6059gj8/html-images/image026_en.png"><img border="0" width="496" height="426" id="圖片 3" src="/content/dam/richtek-eds/resources/evaluation-boards/evb_rtq6059gj8/html-images/image026_en.png" alt="Technical Document Image Preview" /></a> Figure 24.

19. Single Register Read/Write

Figure 26 demonstrates the capability to read and write to individual registers through the GUI. Step 1. Select the register to Read/Write. <a class="fancybox" href="/content/dam/richtek-eds/resources/evaluation-boards/evb_rtq6059gj8/html-images/image028_en.png"><img border="0" width="380" height="349" id="圖片 5" src="/content/dam/richtek-eds/resources/evaluation-boards/evb_rtq6059gj8/html-images/image028_en.png" alt="Technical Document Image Preview" /></a> Figure 26.

The capacitance values of the input and output capacitors will influence the input and output voltage ripple. 2. MLCC capacitors have degrading capacitance at DC bias voltage, and especially smaller size MLCC capacitors will have much lower capacitance.
