NCP392B: Adjustable front end Overvoltage Protection Controller with protected Vbus output and input spike up to 100 V compliant

Description: The NCP392 is an Overvoltage front end protection ...
  • The NCP392 is an Overvoltage front end protection and be able to disconnect the systems from its output pin in case wrong input operating conditions are detected, up to +28 V. Thanks to this device using internal NMOS, no external device is necessary, reducing the system cost and the PCB area of the application board. Internal OVLO threshold is available, or can be adjusted if external resistor bridge is used (A version). At power up (ENpin= low level), the Vout turns on tstart time after internal timer elapsed. Additional timer option is available in the B version for OTG supporting. A LDO, internally connected on IN pin, provided a protected output voltage even if an over voltage is present on IN pin.
  • Features
  • Over-voltage Protection Up to + 28V - Improves system robustness
  • On-chip low Rdson NMOS transistors: Typical 34 mΩ - Low dissipation, allowing high charging current
  • Fixed and externally adjustable OVLO (5.95 V default) - Flexibility
  • + 100 V surge capability, in compliance with IEC61000-4-5 both 1.2/50us and 10/700us - Robust to hot plug generated surges
