When overcurrent protection is tripped, a load switch IC operates in foldback current control mode. Foldback is a current limiting feature. When the load is short-circuited, foldback reduces the output current (IOUT) as the output voltage (VOUT) decreases. When VOUT = 0 V, foldback limits the output current to a level that is internally determined by the load switch IC. When the overcurrent condition has disappeared, VOUT returns to the normal level automatically.
Foldback prevents the heating of a load switch IC in the event of overcurrent conditions. Overcurrent protection is tripped when the output current exceeds the rated level. It is thus intended to provide temporary protection. Be sure to shut down a system so that the overcurrent condition does not last for an extended period of time.
