Fixed Current-Limiting Power-Distribution Switches
NCP382
The NCP382 is a single input dual outputs high side power−distribution switch designed for applications where heavy capacitive loads and short−circuits are likely to be encountered. The device includes an integrated 80 mW, P−channel MOSFET. The device limits the output current to a desired level by switching into a constant−current mode when the output load exceeds the current−limit threshold or a short is present. The current−limit threshold is internally fixed. The power−switches rise and fall times are controlled to minimize current ringing during switching.
The FLAG logic output asserts low during overcurrent or overtemperature conditions. The switch is controlled by a logic enable input active high or low.
