NCP383

NCP383 Adjustable Current-Limiting Power-Distribution Switches The NCP383 is a single input dual outputs power−distribution switch designed for applications where heavy capacitive loads and short−circuits are likely to be encountered, incorporating two very low RDS(on), N−channel MOSFETs in a single package. Each channel of 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 circuit is present. The current−limit threshold is externally fixed by a pull down resistor placed between Ilim and GND. The power−switches rise and fall times are controlled to minimize current ringing during turn on/off. An internal reverse−voltage detection comparator disables the power−switch if the output voltage is higher than the input voltage to protect devices on the input side of the switches. The /FLAGx logic output asserts low during over−current, reverse−voltage or over temperature conditions. The switch is controlled by a logic enable input active low.
