NCT3521U-2 Description

Short technical summary and product information.

The NCT3521U-2 from Nuvoton Technology is an integrated power switch IC featuring an 80mΩ on-resistance, suitable for high-side load switching applications. This device is designed to operate with an input voltage range of 3V to 5.5V, making it compatible with both 3V and 5V systems.

 

Key features include under-voltage lockout, current limiting, and thermal shutdown for protection against overloads and short circuits. The NCT3521U-2 also incorporates a shutdown discharge function and a soft-start function. Its low quiescent current, less than 1uA in shutdown mode, and small package size make it an ideal choice for battery-powered equipment.

 

This power switch IC is designed for applications requiring efficient and protected load switching. Its integrated protection mechanisms help prevent damage from excessive power dissipation during heavy load conditions or short circuit events.
