Product Overview
Product Description
NCP361 is able to disconnect the system from its output pin in case wrong VBUS operating conditions are detected. The system is positive overvoltage protected up to +20 V. Thanks to the integrated PMOS FET, no external device is necessary, reducing the system cost and the PCB area of the application board. NCP361 is able to instantaneously disconnect the output from the input if the input voltage exceeds the overvoltage threshold (OVLO).Thanks to an overcurrent protection, the integrated PMOS is turning off when the charge current exceeds current limit (see options in ordering information). NCP361 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 1.0 µF or larger capacitor.
Features   Benefits
     
  • Very Fast Protection, Up to 20 V, with 25 µA Current Consumption
 
  • When wall adapter or AC-DC overvoltage appears, the internal pass element is turned off very fast in order to protect the downstream system. The current consumption is around 25 µA although the very fast turn off capability.
  • On-chip PMOS Transistor
 
  • No external device is necessary.
  • Overvoltage Lockout (OVLO)
 
  • Typical OVLO is set to 5.675 V. Additional thresholds can be manufactured. Please contact your ON Semiconductor Sales contact for further information.
  • Undervoltage Lockout (UVLO)
 
  • Typical UVLO is set to 3.0 V. Additional thresholds can be manufactured. Please contact your ON Semiconductor Sales contact for further information.
  • Overcurrent Protection.
 
  • Typical OCP is set to 750 mA. Additional thresholds can be manufactured. Please contact your ON Semiconductor Sales contact for further information.
  • Alert FLAG Output
 
  • The microcontroller can take into account Flag status and controls thanks to EN pin the pass element state.
  • EN Enable Pin
 
  • The OVP device can be forced to off state thanks to this pin.
  • Thermal Shutdown
 
  • When internal junction temperature is exceeded, the pass element is turned off.
  • 6-Lead UDFN 2 x 2 mm Package
