. 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.
