NCV360SNAFT1G

Power Supply Controllers, Monitors Overview

The NCV360SNAFT1G is a USB overvoltage protection controller manufactured by onsemi, designed for automotive applications. It operates within a supply voltage range of 1.2 V to 20 V and draws a typical quiescent current of 24 uA. The device functions as a protection controller with an integrated internal PMOS FET and status flag output. It is qualified to AEC-Q100 standards and housed in a TSOP-5 surface-mount package. The component supports operation across a temperature range from -40°C to +85°C.

Power Supply Controllers, Monitors Feature Summary

• Integrates an internal PMOS FET for efficient power path management
• Provides overvoltage protection with a dedicated status flag output
• Qualified for automotive environments under AEC-Q100 standards

Power Supply Controllers, Monitors Applications

• USB port protection in automotive infotainment systems
• Overvoltage safeguarding for USB interfaces in vehicle electronics
• Power distribution protection in automotive control modules

Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix 'N' indicates automotive qualification and 'AFT' defines the tape and reel packaging configuration. Confirm that the part number matches the required AEC-Q100 grade and TSOP-5 package dimensions. Ensure compatibility with the intended operating temperature range and interface requirements before procurement.

Power Supply Controllers, Monitors Selection Notes

Select this component when automotive-grade reliability is required for USB overvoltage protection. The integrated PMOS reduces external component count compared to discrete solutions. Consider the 24 uA quiescent current for low-power standby applications. Verify that the 20 V maximum supply voltage aligns with the system's transient voltage specifications.

Power Supply Controllers, Monitors Part Context

This part belongs to the NCP360 series of USB interface controllers. It serves as a specialized protection device rather than a data controller. The series includes variants for different packaging and automotive qualifications. The NCV prefix specifically denotes the automotive qualified version of the standard NCP360 family.

Power Supply Controllers, Monitors Replacement Considerations

The NCP360SNAFT1G is the commercial equivalent of the NCV360SNAFT1G. Verify if the application requires automotive qualification; if not, the commercial variant may be suitable. Check datasheet parameters for pinout and electrical characteristics compatibility before substitution.
