DATA SHEET www.onsemi.com Fixed/Adjustable Current‐Limiting Power‐Distribution Switches UDFN6 CASE 517AB TSOP−5 CASE 483 MARKING DIAGRAMS NCP380, NCV380 1 2 3 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. 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. 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.

The NCP380 is a high side P channel MOSFET power distribution switch designed to protect the input supply voltage in case of heavy capacitive loads, short circuit or over current. In addition, the high side MOSFET is turned off during under voltage, thermal shutdown or reverse voltage condition. Adjustable version allows the user to program the current limit threshold using an external resistor. Thanks to the soft start circuitry, NCP380 is able to limit large current and voltage surges. VOUT Thermal Regulation Threshold Timer Regulation Mode IOUT IOCP Overcurrent Protection NCP380 switches into a constant current regulation mode when the output current is above the IOCP threshold. Depending on the load, the output voltage is decreased accordingly. • In case of hot plug with heavy capacitive load, the output voltage is brought down to the capacitor voltage. The NCP380 will limit the current to the IOCP threshold value until the charge of the capacitor is completed. TOCP Figure 24. Short circuit Then, the device enters in timer regulation mode, described in 2 phases: • Off-phase: Power MOSFET is off during TOCP to allow the die temperature to drop. • On-phase: regulation current mode during TREG. The current is regulated to the IOCP level. VOUT Drop due to Capacitor Charge The timer regulation mode allows the device to handle high thermal dissipation (in case of short circuit for example) within temperature operating condition. NCP380 stays in on-phase/off-phase loop until the over current condition is removed or enable pin is toggled. IOUT IOCP Remark: Other regulation modes can be available for different applications. Please contact our onsemi representative for availability. Figure 22. Heavy capacitive load • In case of overload, the current is limited to the IOCP FLAG Indicator value and the voltage value is reduced according to the load by the following relation: V OUT + R LOAD I OCP TREG The FLAG pin is an open-drain MOSFET asserted low during over current, reverse-voltage or over temperature conditions. When an over current or a reverse voltage fault is detected on the power path, FLAG pin is asserted low at the end of the associate deglitch time (see electrical characteristics). Thanks to this feature, the FLAG pin is not tied low during the charge of a heavy capacitive load or a voltage transient on output. Deglitch time is TFOCP for over current fault and TREV for reverse voltage. The FLAG pin remains low until the fault is removed. Then, the FLAG pin goes high at the end of TFGL. (eq. 1) VOUT IOCP × RLOAD IOUT IOCP Undervoltage Lock-out Thanks to a built-in under voltage lockout (UVLO) circuitry, the output remains disconnected from input until VIN voltage is below VUVLO. When VIN voltage is above VUVLO, the system try to reconnect the output after a rearming time. TRUVLO. This circuit has a VHYST hysteresis witch provides noise immunity to transient. Figure 23. Overload • In case of short circuit or huge load, the current is limited to the IOCP value within TDET time until the short condition is removed. If the output remains shorted or tied to a very low voltage, the junction temperature of the chip exceeds TSDOCP value and the www.onsemi.com 15 NCP380, NCV380 Thermal Sense well established and stablized prior to enabling the IC. If no separate EN signal is available, a 10 kW/100 nF RC network can be added between VIN and EN to delay the EN signal. A logic low on EN or high on EN turns-on the device. A logic high on EN or low on EN turns off device and reduces the current consumption down to IINOFF. Thermal shutdown turns off the power MOSFET if the die temperature exceeds TSD. A Hysteresis prevents the part from turning on until the die temperature cools at TRSD. Reverse Voltage Protection When the output voltage exceeds the input voltage by VREV voltage during TREV, the reverse voltage circuitry disconnects the output in order to protect the power supply. The same time TREV is needed to turn on again the power MOS plus a rearming time TRREV. Blocking Control The blocking control circuitry switches the bulk of the power MOS. When the part is off, the body diode limits the leakage current IREV from OUT to IN. In this mode, anode of the body diode is connected to IN pin and cathode is connected to OUT pin. In operating condition, anode of the body diode is connected to OUT pin and cathode is connected to IN pin preventing the discharge of the power supply. Enable Input Enable pin must be driven by a logic signal (CMOS or TTL compatible) or connected to the GND. VIN and EN should not be connected together directly. VIN should be APPLICATION INFORMATION Power Dissipation Adjustable Current-Limit Programming (for adjustable version only) The junction temperature of the device depends on different contributing factors such as board layout, ambient temperature, device environment, etc... Yet, the main contributor in terms of junction temperature is the power dissipation of the power MOSFET. Assuming this, the power dissipation and the junction temperature in normal mode can be calculated with the following equations: R D + R DS(on) Where: PD RDS(on) IOUT 2 (eq. 2) = Power dissipation (W) = Power MOSFET on resistance (W) = Output current (A) TJ + PD Where: TJ RqJA TA ǒIOUTǓ The NCP380xMUAJAA and NCP380xSNAJAA, respectively mDFN and TSOP6 packages, are proposed to have current limit flexibility for end Customer. Indeed, Ilim pin is available to connect pull down resistor to ground, which participate to the current threshold adjustment. It’s strongly recommended to use 0.1 or 1% resistor tolerance to keep the over current accuracy. For this resistance selection, Customer should define first of all, the USB current to sustain, without the device enters in the protection sequence. Main rule is to select this pull down resistor in order to make sure min current limit is above the USB current to provide continuously to the upstream accessory. Following, the main table selection contains the USB current port for the accessory, the standard resistor selection and typical/max over current threshold. R qJA ) T A (eq. 3) = Junction temperature (°C) = Package thermal resistance (°C/W) = Ambient temperature (°C) Power dissipation in regulation mode can be calculated by taking into account the drop VIN−VOUT link to the load by the following relation: P D + ǒV IN * R LOAD Where: PD VIN RLOAD IOCP I OCPǓ I OCP (eq. 4) = Power dissipation (W) = Input Voltage (V) = Load Resistance (W) = Output regulated current (A) www.onsemi.com 16 NCP380, NCV380 Table 5.

Current Threshold vs. Rlim Resistor PCB Recommendations That is recommended to respect 6 kW−47 kW resistor range for two reasons. For the low resistor values, the current limit is pushed up to high current level. Due to internal power dissipation capability, a maximum of 2.4 A typical can be set for the mDFN package if thermal consideration are respected. For the TSOP6 version 1.2 A is the maximum recommended value because the part could enter in thermal shutdown mode before constant current regulation mode. In the other side, if we want to keep 15% of accuracy, high resistor values can be used up to 50 kW. With higher value, the current threshold is lower than 500 mA, so in this case degraded accuracy can be observed. The NCP380 integrates a PMOS FET rated up to 2 A, and the PCB design rules must be respected to properly evacuate the heat out of the silicon. The UDFN6 PAD1 must be connected to ground plane to increase the heat transfer if necessary. This pad must be connected to ground plane. By increasing PCB area, the RqJA of the package can be decreased, allowing higher power dissipation. www.onsemi.com 18 www.onsemi.com 19 Figure 27.
