ON Semiconductor NCP380HMU21AATBG Overview

The ON Semiconductor NCP380HMU21AATBG is a high-performance, current-limiting, power-distribution switch designed to provide a feature-rich solution for power management requirements. This device is specifically engineered to enhance system reliability by providing robust circuit protection and power control functionalities.

Key Features

• Current Limiting: The NCP380 offers an adjustable current limit feature, which helps prevent damage to the host device due to overcurrent conditions. It ensures that the current does not exceed a safe threshold, safeguarding sensitive electronic components.
• Thermal Shutdown Protection: With an integrated thermal shutdown mechanism, the device protects itself and the downstream circuitry from damage due to excessive heat. This feature is vital for maintaining the longevity and reliability of the system.
• Reverse Current Blocking: This function prevents current from flowing backward into the source, which is critical for battery-powered applications where power conservation is crucial.
• Under-Voltage Lockout (UVLO): The UVLO feature ensures that the switch remains off if the input voltage drops below a certain threshold, preventing erratic behavior of the powered device due to insufficient supply voltage.

Applications

The NCP380HMU21AATBG is suitable for a variety of applications, including but not limited to:

• Portable and battery-powered devices
• USB hubs, ports, and peripherals
