描述 Description

The NCP383 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, incorporating two very low RDSON, Nchannel 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 is present. The current limit threshold is externally fixed with 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 overcurrent, reverse voltage or over temperature conditions. The switch is controlled by a logic enable input active high or low.
