3.1.7

USB PHY Suspend current consumption

3.1.7.1

Low power Suspend Mode

The VBUS Valid comparators and their associated bandgap circuits are enabled by default. Table 12

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

3.1.7.2

Power-Down modes

Table 13 shows the USB interface current consumption with only the OTG block powered down.

In Power-Down mode, everything is powered down, including the USB_VBUS valid comparators and

their associated bandgap circuity in typical condition. Table 14 shows the USB interface current

consumption in Power-Down mode.

1 VBUS Valid comparators can be disabled through software by setting USBNC_OTG*_PHY_CFG2[OTGDISABLE0] to 1. This signal

powers down only the VBUS Valid comparator, and does not control power to the Session Valid Comparator, ADP Probe and Sense

comparators, or ID detection circuitry.

1 The VBUS Valid Comparators and their associated bandgap circuits can be disabled through software by setting

USBNC_OTG*_PHY_CFG2[OTGDISABLE0] to 1 and USBNC_OTG*_PHY_CFG2[DRVVBUS0] to 0, respectively.
