Power Sequence Timing
Power supplies must adhere to the following rules:
All power supplies of the same voltage must be powered up/down together.
There is no power-up sequencing requirement, however all power supplies must reach operational
levels within the time periods specified in
There is no power-down sequencing or timing requirement, however the device must not be
powered for an extended period of time without all supplies at operational levels.
Following initial power-on, or if a power supply brownout occurs (i.e., one or more supplies drops
below operational limits), a power-on reset must be executed once all power supplies reach
operational levels. Refer to
requirements.
With the exception of VBUS_DET, do not drive input signals without power supplied to the device.
Note: Violation of these specifications may damage the device.
