Note：Inrush is defined as the highest possible charge transferred to the power pins of the engine when
PWR_EN signal is High. Higher short current spikes occur when power is applied to the power pins of the
engine. These spikes are related to the presence of capacitors at the input of power rails of the engine:
VIN_3V3_IMGR：20uF
VIN_3V3_LED：22uF
The value of these spikes may vary with current capabilities of a power supply and resistance of the
power path. Circuitry may be added to limit the rate of charge transfer and keep the peak current down
during start-up.
