(2) when the output short - circuits or high capacity load is connected while the switch is on , very large cu rrent flows until the over - current limit circuit reacts. when the current detection and limit circuit operates , current limitation is carried out. 5v( t yp) c in in out regulator out out out in in /oc gnd vbus d - d+ gnd usb controller 5v(typ.) 10k 100k
