Notes:
1. The USB Pull-up supply current values are calculated values based on USB specifications. USB Pull-up supply current
is current flowing from V
DD
to GND through USB pull-down/pull-up resistors on D+ and D-.
2. Thermal resistance assumes a multi-layer PCB with any exposed pad soldered to a PCB pad.
3. USB Pull-up current should be added for total supply current. Normal and suspended supply current is current flowing
into V
REGIN
. Normal and suspended supply current is guaranteed by characterization.
