ON Semiconductor NCP380HMU15AATBG Overview

The NCP380HMU15AATBG from ON Semiconductor is a high-performance current limiting switch designed for applications requiring protection against high inrush current and short circuits. This advanced power management device is ideal for systems that need to regulate power supply and safeguard sensitive electronics against damage caused by excessive current flow.

Key Features

• Current Limiting: The NCP380 offers a fixed current limit threshold of 1.5 A, providing a robust defense against overcurrent conditions that could potentially harm the circuitry.
• Ultra-Low R_DS(on): With an ultra-low on-resistance, this current limiting switch ensures minimal voltage drop and power loss, enhancing overall system efficiency.
• Thermal Shutdown: The device includes a thermal shutdown feature, which automatically turns off the output when the junction temperature exceeds safe operating limits, thereby preventing thermal runaway.
• Under-Voltage Lockout (UVLO): The UVLO function ensures that the device operates only when the input voltage is within an acceptable range, protecting the downstream circuitry from undervoltage conditions.

Applications

The NCP380HMU15AATBG is well-suited for a wide range of applications, including but not limited to:

• Portable and battery-powered devices
