power saving. For example, the PMIC can change the DCDC rails to PFM mode to reduce the power

consumption.

The power consumption in low power modes is defined in Table 15.

All the power numbers defined in Table 15 are based on typical silicon at 25°C.

USB PHY Suspend current consumption

4.1.7.1

Low Power Suspend Mode

The VBUS Valid comparators and their associated bandgap circuits are enabled by default. Table 16

shows the USB interface current consumption in Suspend mode with default settings.
