Section 3. Evaluation Kit Test Set-up
3.1 Hardware Setup
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). If needed, refer to the datasheet for further clarification.
Figure 6: EVB to MPS I2C Communication Interface Wire Connection
3.2 Powering up the EVB
1. Connect the positive and negative terminals of the load to the SYS and GND pins, respectively.
2. Connect the positive and negative terminals of the battery to the VBATT and GND pins, respectively.
If it is a battery simulator, preset the battery voltage between 0V and 4.545V, then turn it off. Connect
the battery simulator output to the VBATT and GND pins respectively.
3. Preset the power supply output between 3.9V and 7.0V, and then turn off the power supply. Connect
the positive and negative terminals of the power supply output to the VIN and GND pins, respectively.
4. Make sure the battery voltage has been preset (if a battery simulator is used, turn on the battery
emulator). Turn the power supply on. The IC will enter the power on sequence automatically.
Reminder: if the battery simulator is connected, please make sure to turn on the battery emulator first,
before the input supply in the start-up sequence.
3.3 Software Set-Up
After connecting the hardware according to Section 3.1 and Section3.2, follow the steps below to use the
GUI software:
1. Start the software. It will check the EVB connection automatically.
If connection is successful, both the USB and MP2663 DEMO board statuses are "connected".
(See Figure 7).

Figure 7: Appearance of USB and MP2663 EVB Board Show Connected
If connection is not successful, "Not Connected" will appear in red. Check connections between
the EVB, communication interface, and PC. Re-plug the USB into the computer.
1) MP2663 DEMO Board “Not Connected" means that the evaluation board is not connected
correctly.
2) USB “Not Connected" means that the USB I2C communication interface is not connected
correctly.
2. Click the “Read All Register” button to read the I2C register values and the default values are
displayed (see Figure 7).
3. Find the item you want to change and select the desired value from the drop down menu.
4. Click the “Write All” button to update values. The changed information of the item will be downloaded
to the IC.
All changes made via the I2C will be restored to default values once the EVB is powered down.

3.5 Troubleshooting Tips
EVKT-USBI2C-02 Driver Problem
If the USBI2C-02 driver is not properly installed, manual installation is required. Follow the steps below.
1. Install the correct “.exe” file according to the windows operation system.
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 a USB cable.
3. Find the “USBXpress Device” in the Device Manager.
If the PC is running Windows10, check the driver version of USBXpress Device. Windows 10 will
automatically install the older USB driver, which is not compatible. The correct driver version is 4.0.0.0
(see Figure 12).
Figure 12: Correct Driver Version is 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
lower than the UVLO rising threshold, the charging function is disabled.
No Charging Event
If the IC detects that the input voltage is lower than the UVLO falling threshold (it enters a no supply state)
or over-temperature protection is triggered (it enters a shutdown state), the IC switches to supplement
mode powered by the battery.
Thermal Recovery
If the MP2663 is in a shutdown state due to the die temperature exceeding the thermal protection
threshold, the IC enters a power-on sequence when the die’s temperature decreases.
