NCP361, NCV361 USB Positive Overvoltage Protection Controller with Internal PMOS FET and Overcurrent Protection www.onsemi.com The NCP361 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 MARKING necessary, reducing the system cost and the PCB area of the DIAGRAMS application board. The NCP361 is able to instantaneously disconnect the output from 6 PIN UDFN 1 xx M CASE 517AB the input if the input voltage exceeds the overvoltage threshold (5.675 V). Thanks to an overcurrent protection, the integrated PMOS is turning off when the charge current exceeds current limit (see 5 options in ordering information). 1 The NCP361 provides a negative going flag (FLAG) output, which xxx AYW alerts the system that voltage, current or overtemperature faults have TSOP5 CASE 483 occurred. 1 In addition, the device has ESDprotected input (15 kV Air) when bypassed with a 1 F or larger capacitor. xxx = Specific Device Code M = Date Code Features A = Assembly Location Overvoltage Protection up to 20 V Y = Year W = Work Week On chip PMOS Transistor = PbFree Package Overvoltage Lockout (OVLO) (Note: Microdot may be in either location) Undervoltage Lockout (UVLO) Overcurrent Protection PIN CONNECTIONS Alert FLAG Output EN Enable Pin EN 1 6 FLAG Thermal Shutdown GND 2 5 OUT Compliance to IEC6100042 (Level 4) 8 kV (Contact) IN 3 4 OUT 15 kV (Air) ESD Ratings: Machine Model = B UDFN ESD Ratings: Human Body Model = 2 OUT UDFN6 2x2 mm and TSOP 5 3x3 mm Packages IN 1 5 NCV Prefix for Automotive and Other Applications Requiring GND 2 Unique Site and Control Change Requirements AECQ100 Qualified and PPAP Capable FLAG EN 3 4 This is a PbFree Device TSOP5 Applications (Top View) USB Devices Mobile Phones ORDERING INFORMATION Peripheral See detailed ordering and shipping information in the package dimensions section on page 10 of this data sheet.

Functional Block Diagram PIN FUNCTION DESCRIPTION UDFN Package) Pin No. Name Type Description 1 EN INPUT Enable Pin. The device enters in shutdown mode when this pin is tied to a high level. In this case the output is disconnected from the input. To allow normal functionality, the EN pin shall be connected to GND or to a I/O pin. This pin does not have an impact on the fault detection. 2 GND POWER Ground 3 IN POWER Input Voltage Pin. This pin is connected to the VBUS. A 1 F low ESR ceramic capacitor, or larger, must be connected between this pin and GND. 4, 5 OUT OUTPUT Output Voltage Pin. The output is disconnected from the VBUS power supply when the input voltage is above OVLO threshold or below UVLO threshold. A 1 F capacitor must be connected to these pins. The two OUT pins must be hardwired to common supply. 6 FLAG OUTPUT Fault Indication Pin. This pin allows an external system to detect a fault on VBUS pin. The FLAG pin goes low when input voltage exceeds OVLO threshold. Since the FLAG pin is open drain functionality, an external pull up resistor to V must be added. CC PIN FUNCTION DESCRIPTION (TSOP5 Package) Pin No. Name Type Description 1 IN POWER Input Voltage Pin. This pin is connected to the VBUS. A 1 F low ESR ceramic capacitor, or larger, must be connected between this pin and GND. 2 GND POWER Ground 3 EN INPUT Enable Pin. The device enters in shutdown mode when this pin is tied to a high level. In this case the output is disconnected from the input. To allow normal functionality, the EN pin shall be connected to GND or to a I/O pin. This pin does not have an impact on the fault detection. 4 FLAG OUTPUT Fault Indication Pin. This pin allows an external system to detect a fault on VBUS pin. The FLAG pin goes low when input voltage exceeds OVLO threshold. Since the FLAG pin is open drain functionality, an external pull up resistor to V must be added. CC 5 OUT OUTPUT Output Voltage Pin. The output is disconnected from the VBUS power supply when the input voltage is above OVLO threshold or below UVLO threshold. A 1 F capacitor must be connected to this pin.
