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

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

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.

= Wafer Lot

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.
