Figure 13. USB Current-Limit Threshold vs RILIM Over Temperature and Process, VIN = 3.3 V, IAUX = 0 A
In addition to current-limit shifts due to process and temperature, the operating conditions of the boost converter
also affect the current-limit threshold of the USB switch. Figure 13 accounts for process and temperature shifts at
VIN = 3.3 V and IAUX = 0 A. The following figures show current-limit shift trends over VIN and IAUX (where IAUX is
the auxiliary 5-V load current provided to any non-USB loads). These curves can be used to calculate the USB
current-limit threshold shift for a given application where the input voltage VIN range and auxiliary current IAUX
vary.
