Evaluation Kit Test Set-Up 3.1 Hardware Set-Up The hardware must be properly configured prior to use. Follow the instructions below to set up the EVB: 1. Locate the proper wires to connect the EVB to the EVKT-USBI2C-02 communication interface. 2. Connect SCL, SDA, and GND (see Figure 6). Refer to the MP2723 datasheet for further clarification. Figure 6: EVB to MPS I2C Communication Interface Wire Connection 3.2 Powering Up the EVB 1. Connect the load to: a. Positive (+): VSYS b. Negative (-): PGND 2. Connect the battery terminals to: a. Positive (+): VBATT b. Negative (-): PGND 3. If using a battery simulator, preset the battery voltage between 0V and 4.2V, then turn it off. a. Connect the battery simulator output to the BATT and PGND pins, respectively. 4. Preset the power supply output between 3.7V and 5.5V, then turn off the power supply. 5. Connect the power supply output terminals to: a. Positive (+): VIN b. Negative (-): PGND 6. Ensure the battery voltage is present (if a battery simulator is used, turn on the battery simulator). Turn the power supply on. The device should start up automatically. MP2723 Evaluation Kit User Guide Rev. 1.0 MonolithicPower.com 6/1/2020 MPS Proprietary Information. Patent Protected.

Start the software. It should automatically check the EVB connection.  If the connection is successful, both the USB and MP2723 demo board statuses will be listed as “Connected” (see Figure 7). Figure 7: Connected USB and MP2723 Demo Board  If the connection is unsuccessful, they will be listed as “Not Connected” in red. In this case, check the connections between the EVB, communication interface, and PC. Re-plug the USB into the computer. 1) If the MP2723 demo board is listed as “Not Connected,” this means that the evaluation board is not connected correctly. 2) If the USB is listed as “Not Connected,” this means that the USB I2C communication interface is not connected correctly. 2. Click the “Read All” button to read the I2C register values. The default values are displayed (see Figure 7). 3. Find the item to be changed, and select the desired value from the drop-down menu. 4. Click the “Write All” button to update values. The changed information should then download to the IC. ⚠️ All changes made via I2C will be restored to default values once the EVB shuts down.

Follow the steps below: 1. Install the correct USBXpress “.exe” file according to the Windows operating system (32-bit or 64-bit). 32-bit: \EVKT-USBI2C-02 USB Driver\USBXpressInstaller_x86.exe 64-bit: \EVKT-USBI2C-02 USB Driver\USBXpressInstaller_x64.exe 2. Connect the communication interface to the PC with the USB cable. 3. Find “USBXpress Device” in the Device Manager under USB controllers. Note: Ensure the driver version matches the newest version. Right-click and view properties. If the PC is running Windows 10, Windows 10 may automatically install the older USB driver, which is not compatible. The correct driver version should be newer than 4.0.0.0 (see Figure 8). Figure 8: Correct Driver Version Should Be Newer than 4.0.0.0 No Supply The IC’s input pin has an under-voltage lockout (UVLO) detection circuit. If the input voltage (VIN) is below the UVLO rising threshold, the charging function is disabled. No Charging Event If the IC detects that the input voltage is below the UVLO falling threshold (device enters a no-supply state) or over-temperature protection is triggered (device enters a shutdown state), the IC stops switching and charging is suspended. Thermal Recovery If the MP2723 is in a shutdown state due to the die temperature exceeding the thermal protection threshold, the IC powers on again once the die temperature decreases.
