The current through the external NFETs to VBUS is current limited when acting as a source or a sink. The current is sensed across the external RSENSE resistance. The current limit is set by a combination of the RSENSE magnitude and configuration settings for the voltage across the resistance. When the voltage across the RSENSE resistance exceeds the automatically set voltage limit, the current-limit circuit is activated.
