All Rights Reserved. 12 User Guide MP5416 Evaluation Kit (EVKT-5416) The remaining steps are optional and instruct how to check that new configurations have been programmed. Optional: 17. Adjust the input voltage to 3.5 - 5V. 18. Repeat steps 1-3 from this section. 19. If done correctly, new configurations will be shown in the table on the left hand side. Notes:  Unlike in I2C, not all of the configurations you set in OTP mode will be displayed until you write to MP5416-CCCC and power cycle.  After OTP, you: o Are still able to change values using the I2C. o Do not need to press P1 while powering on the board.  If you try to perform OTP on a previously programmed device, the GUI software will allow you to proceed normally. However, your configurations will NOT be saved. 3.5 Troubleshooting Tips Note: USBI2C-02 and USBI2C-01 drivers are not compatible. USBI2C-02 uses USBXpress and USBI2C uses Cyusb3. USBI2C-02 is the recommended device for MPS PMBus and I2C. EVKT-USBI2C-01 In case that the USBI2C-01 driver is not properly installed, manual installation is required. Follow the steps below. 1. Open the Device Manager and select update driver software (see figure 19). 2. Click “Browse my computer for driver software”, find the downloaded driver and install. Figure 19 EVKT-USBI2C-02 In the case that the USBI2C-02 driver is not properly installed, manual installation is required. Follow the steps below. Note: Check driver version. Find “USBXpress” Device in the Device Manager under USB controllers. Right click and view properties Check to make sure the driver version matches the newest version.

Install the correct USBXpress “.exe” file Choose either 32 bit or 64 bit operating system. 32-bit: USBXpressInstaller_x86.exe 64-bit: USBXpressInstaller_x64.exe 2. Connect the EVKT-USBI2C-02 Dongle to the PC with the USB cable.  No Supply The PMIC’s input pin has an under-voltage lockout (UVLO) detection circuit. If the input voltage (AVIN) is lower than the UVLO rising threshold, the PMIC’s functions are disabled.  Shutdown Event If the PMIC detects that the input voltage is lower than the UVLO falling threshold (enter no supply state) or over-temperature protection is triggered (enter power off state), the PMIC switches to no supply state or power-off state, regardless of the current state.  Thermal Recovery If the MP5416 is in a power-off state due to the die temperature exceeding the thermal protection threshold, the PMIC enters a power-on sequence when the die’s temperature decreases.  Shutdown Sequence When the input voltage is lower than the UVLO falling threshold or the IC is over-temperature, the PMIC enters the shutdown sequence directly.
