NCP380, NCV380 Fixed/Adjustable Current‐Limiting Power‐Distribution Switches 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 m (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 UDFN6 TSOP−5 TSOP−6 CASE 517AB CASE 483 CASE 318G present. The current-limit threshold is either user adjustable between 100 mA and 2.1 A via an external resistor or internally fixed. The MARKING DIAGRAMS power-switch rise and fall times are controlled to minimize current ringing during switching. An internal reverse-voltage detection comparator disables the 1 XXM 6 2 5 power-switch if the output voltage is higher than the input voltage to 3 4 protect devices on the input side of the switch. The FLAG logic output asserts low during over current, UDFN6 reverse-voltage or over temperature conditions. The switch is controlled by a logic enable input active high or low. 5 Features XXXAYW
