NCP391FCCADT2G

Overview

The NCP391FCCADT2G is a positive overvoltage protection controller manufactured by onsemi. It operates within a supply voltage range of 1.2V to 28V and features an internal low RDS(on) NMOS FET for efficient switching. The device is designed for fixed, single-channel applications with an operating temperature range of -40°C to 85°C. It is housed in a compact 6-UFBGA (WLCSP) package, suitable for space-constrained designs requiring reliable voltage monitoring and protection.

Feature Summary

• Integrates an internal low resistance NMOS FET to minimize conduction losses during protection events
• Provides dedicated positive overvoltage protection functionality for power lines
• Supports wide input supply voltage ranges up to 28V for versatile system integration

Applications

• Overvoltage protection controllers in electronic systems
• Power management circuits requiring voltage monitoring
• Portable devices needing compact power protection solutions

Procurement Notes

Verify the specific suffix 'FCCADT2G' against the official datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure the component status is current, as availability may vary. Confirm RoHS compliance and lead-free status if required by your manufacturing standards before finalizing procurement orders.

Selection Notes

Select this component when a compact solution for positive overvoltage protection is needed. The integrated NMOS FET reduces external component count compared to discrete solutions. Consider the 6-UFBGA package size for PCB layout constraints. Verify that the 28V maximum supply voltage aligns with your system's operational limits.
