ON Semiconductor NCP380LMU20AATBG - Overvoltage Protection Controller

The NCP380LMU20AATBG from ON Semiconductor is a high-performance, fixed 2.0 V overvoltage protection device designed to protect sensitive electronic components from harmful voltage levels that exceed its threshold. This compact and efficient integrated circuit is a crucial component for modern electronics, ensuring longevity and reliability of the system it's integrated into.

Featuring a current limit of up to 2.0 A, the NCP380LMU20AATBG provides robust protection for a variety of USB applications, including USB ports on personal computers, peripherals, and portable devices. Its low quiescent current and high accuracy make it an ideal choice for battery-powered applications where power efficiency is paramount.

The device comes in a small, space-saving 6-pin μDFN package, making it suitable for space-constrained applications. With its quick response time, the NCP380LMU20AATBG rapidly disconnects the output from the input if the input voltage exceeds the overvoltage threshold, thereby protecting downstream components from potential damage.

Key features of the NCP380LMU20AATBG include:

• Fixed 2.0 V Overvoltage Protection Threshold
• 2.0 A Current Limit Capability
• Low R<sub>DS(on) NMOS FET for reduced power dissipation
• Low Quiescent Current
