The NCP380 is a 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 55 mW (DFN

package), P-channel MOSFET. The device limits the output current to

a desired level by switching into a constant-current regulation mode

when the output load exceeds the current-limit threshold or a short is

present. The current-limit threshold is either user adjustable between

500 mA and 2.1 A via an external resistor or internally fixed. The

power-switch rise and fall times are controlled to minimize current

ringing during switching.

MARKING DIAGRAMS

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 switch.

XXMG

The FLAG logic output asserts low during over current,

reverse-voltage or over temperature conditions. The switch is

controlled by a logic enable input active high or low.
