DATA SHEET www.onsemi.com Fixed/Adjustable CurrentLimiting UDFN6 TSOP5 TSOP6 PowerDistribution CASE 517AB CASE 483 CASE 318G Switches MARKING DIAGRAMS NCP380, NCV380 1 6 XXM 2 5 The NCP380 is a high side power-distribution switch designed for 3 4 applications where heavy capacitive loads and short-circuits are likely to be encountered. The device includes an integrated 55 m (DFN UDFN6 package), P-channel MOSFET. The device limits the output current to a desired level by switching into a constant-current regulation mode 5 when the output load exceeds the current-limit threshold or a short is XXXAYW present. The current-limit threshold is either user adjustable between 500 mA and 2.1 A via an external resistor or internally fixed. The 1 power-switch rise and fall times are controlled to minimize current TSOP5 ringing during switching. 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. XXXAYW The FLAG logic output asserts low during over current, reverse-voltage or over temperature conditions. The switch is 1 controlled by a logic enable input active high or low.

PIN FUNCTION DESCRIPTION Pin Name Type Description EN INPUT Enable input, logic low/high (i.e. EN or EN) turns on power switch GND POWER Ground connection IN POWER Power-switch input voltage connect a 1 F or greater ceramic capacitor from IN to GND as close as pos- sible to the IC. FLAG OUTPUT Active-low open-drain output, asserted during overcurrent, overtemperature or reverse-voltage conditions. Connect a 10 k or greater resistor pull-up, otherwise leave unconnected. OUT OUTPUT Power-switch output connect a 1 F ceramic capacitor from OUT to GND as close as possible to the IC is recommended. A 1 F or greater ceramic capacitor from OUT to GND must be connected if the USB requirement (i.e.120 F capacitor minimum) is not met. ILIM* INPUT External resistor used to set current-limit threshold recommended 5 k < R < 250 k .
