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 VDD 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 VREGIN. Normal and suspended supply current is guaranteed by characterization.
