Product Introduction
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 mΩ, 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.
The NCP382 is a dual high side power distribution switches designed to protect the input supply voltage in case of heavy capacitive loads, short circuit or over current. In addition, the high side MOSFETs are turned off during undervoltage or thermal shutdown condition. Thanks to the soft start circuitry, NCP382 is able to limit large current and voltage surges.
NCP382 switches into a constant current regulation mode when the output current is above the IOCP threshold. Depending on the load, the output voltage is decreased accordingly.
The FLAG pin is an open−drain MOSFET asserted low during overcurrent or overtemperature conditions.
