NCP360, NCV360 USB Positive Overvoltage Protection Controller with Internal PMOS FET and Status FLAG The NCP360 disconnects systems at its output when wrong VBUS operating conditions are detected at its input. The system is positive overvoltage protected up to +20 V. Thanks to an integrated PMOS FET, no external device is necessary, reducing the system cost and the PCB area of the application board. The NCP360 is able to instantaneously disconnect the output from the input if the input voltage exceeds the overvoltage threshold (OVLO). The NCP360 provides a negative going flag (FLAG) output, which alerts the system that a fault has occurred. In addition, the device has ESD−protected input (15 kV Air) when bypassed with a 1 mF or larger capacitor.

A PMOS FET protects the systems (i.e.: VBUS) connected on the Vout pin, against positive over−voltage. The Output follows the VBUS level until OVLO threshold is overtaken. NCP360 includes an internal PMOS FET to protect the systems, connected on OUT pin, from positive overvoltage. Regarding electrical characteristics, the RDSon, during normal operation, will create low losses on Vout pin, characterized by Vin versus Vout dropout. (See Figure 16). Undervoltage Lockout (UVLO) To ensure proper operation under any conditions, the device has a built−in undervoltage lock out (UVLO) circuit. During Vin positive going slope, the output remains disconnected from input until Vin voltage is above 3.2 V nominal. The FLAGV output is pulled to low as long as Vin does not reach UVLO threshold. This circuit has a UVLO hysteresis to provide noise immunity to transient condition. ESD Tests NCP360 fully support the IEC61000−4−2, level 4 (Input pin, 1 mF mounted on board). That means, in Air condition, Vin has a ±15 kV ESD protected input. In Contact condition, Vin has ±8 kV ESD protected input. Please refer to Fig 19 to see the IEC 61000−4−2 electrostatic discharge waveform. Vin (V) 20 V OVLO UVLO 0 Vout OVLO UVLO 0 Figure 18. Output Characteristic vs. Vin Overvoltage Lockout (OVLO) To protect connected systems on Vout pin from overvoltage, the device has a built−in overvoltage lock out (OVLO) circuit. During overvoltage condition, the output remains disabled until the input voltage exceeds OVLO − Hysteresis. FLAG output is tied to low until Vin is higher than OVLO. This circuit has a OVLO hysteresis to provide noise immunity to transient conditions. Figure 19. PCB Recommendations The NCP360 integrates a 500 mA rated PMOS FET, and the PCB rules must be respected to properly evacuate the heat out of the silicon. The UDFN PAD1 must be connected to ground plane to increase the heat transfer if necessary from an application standpoint. Of course, in any case, this pad shall be not connected to any other potential. By increasing PCB area, the RqJA of the package can be decreased, allowing higher charge current to fill the battery. Taking into account that internal bondings (wires between package and silicon) can handle up to 1 A (higher than thermal capability), the following calculation shows two different example of current capability, depending on PCB area: • With 305°C/W (without PCB area), allowing DC current is 500 mA • With 260°C/W (200 mm2), the charge DC current allows with a 85°C ambient temperature is: I = √(TJ-TA)/(RqJA x RDSON) I = 625 mA FLAG Output NCP360 provides a FLAG output, which alerts external systems that a fault has occurred. This pin is tied to low as soon the OVLO threshold is exceeded When Vin level recovers normal condition, FLAG is held high. The pin is an open drain output, thus a pull up resistor (typically 1 MW− Minimum 10 kW) must be provided to Vbattery. FLAG pin is an open drain output. EN Input To enable normal operation, the EN pin shall be forced to low or connected to ground. A high level on the pin disconnects OUT pin from IN pin. EN does not overdrive an OVLO or UVLO fault. http://onsemi.com 9 NCP360, NCV360 In every case, we recommend to make thermal measurement on final application board to make sure of the final Thermal Resistance. 380 50% 45% TSOP−5 1.0 oz TSOP−5 2.0 oz DFN 2x2.2 1.0 oz DFN 2x2.2 2.0 oz % Delta DFN vs TSOP−5 Theta JA (C/W) 280 230 40% 35% 30% 25% 20% 180 15% % Delta DFN vs TSOP−5 330 10% 130 5% 80 0 100 200 300 400 500 600 0% 700 Copper heat spreader area (mm^2) Figure 20.
