NCP380 - Fixed/Adjustable Current‐Limiting Power ...

1 DATA Semiconductor Components Industries, LLC, 2016 August, 2021 Rev. 191 Publication Order Number: NCP380 /DFixed/AdjustableCurrent LimitingPower DistributionSwitchesNCP380, NCV380 The NCP380 is a high side Power -distribution switch designed forapplications where heavy capacitive loads and short-circuits are likelyto be encountered. The device includes an integrated 55 mW (DFNpackage), P-channel MOSFET. The device limits the output current toa desired level by switching into a constant-current regulation modewhen the output load exceeds the current-limit threshold or a short ispresent. The current-limit threshold is either user adjustable between500 mA and A via an external resistor or internally fixed. Thepower-switch rise and fall times are controlled to minimize currentringing during internal reverse-voltage detection comparator disables thepower-switch if the output voltage is higher than the input voltage toprotect devices on the input side of the FLAG logic output asserts low during over current,reverse-voltage or over temperature conditions.

In addition, the high side MOSFET is turnedoff during under voltage, thermal shutdown or reversevoltage condition. Adjustable version allows the user toprogram the current limit threshold using an externalresistor. Thanks to the soft start circuitry, NCP380 is able tolimit large current and voltage ProtectionNCP380 switches into a constant current regulation modewhen the output current is above the IOCP on the load, the output voltage is decreasedaccordingly. In case of hot plug with heavy capacitive load, theoutput voltage is brought down to the capacitor NCP380 will limit the current to the IOCP thresholdvalue until the charge of the capacitor is 22.
