NCP380LMU15AATBG

Overview

The NCP380LMU15AATBG is a single-channel high-side power switch IC from the NCP380 series, manufactured by onsemi. It features a P-channel MOSFET with a maximum continuous output current of 2.1 A and an adjustable current limit ranging from 500 mA to 2.1 A. The device operates within a supply voltage range of 2.5 V to 5.5 V and maintains a maximum on-resistance of 75 mOhms. It includes integrated overcurrent protection with a typical run time of 4 ms and idle time of 3 ms. The component is housed in a 6-UDFN (2x2) surface-mount package and is qualified for automotive applications under AEC-Q100 standards.

Feature Summary

• Integrates adjustable overcurrent protection allowing flexible current limit setting between 500 mA and 2.1 A
• Features low on-resistance for efficient power distribution and minimal voltage drop
• Includes built-in fault protection mechanisms such as undervoltage lockout and controlled slew rate
• Provides status flag output for monitoring operational state and fault conditions

Applications

• Automotive electronic control unit power distribution
• High-side switching for automotive sensors and actuators
• Power management in infotainment systems
• Body electronics load protection circuits

Procurement Notes

Verify the specific suffix '15' against official onsemi documentation to confirm the exact current limit configuration, as variations exist within the NCP380 family. Ensure compatibility with AEC-Q100 requirements if used in automotive contexts. Confirm RoHS compliance status through the manufacturer's material declaration. Cross-reference the package marking code with the datasheet to prevent counterfeit substitution. Validate thermal performance specifications against your system's ambient temperature constraints.

Selection Notes

Select this component when a single high-side switch with adjustable current limiting is required for loads up to 2.1 A. The NCP380LMU15AATBG is suitable for applications needing precise overcurrent protection without external sensing components. Consider the 75 mOhm on-resistance for efficiency calculations. The 6-UDFN package offers a compact footprint for space-constrained designs. Ensure the control logic voltage levels align with the 2.5 V to 5.5 V operating range.

Part Context

The NCP380 series represents a family of intelligent high-side switches designed for robust power distribution. This model belongs to the LMU variant line, characterized by specific current limit configurations and package options. It complements other devices like the NCV380 and NCP380HMU series, offering tailored solutions for different current and resistance requirements within automotive and industrial power management architectures.

Replacement Considerations

NCP380LMUAJAATBG: Offers adjustable current limit but may have different on-resistance characteristics. NCP380HMU15AATBG: Fixed 1.5 A limit with lower on-resistance. NCV380LMUAJAATBG: Automotive grade equivalent with similar functionality. Verify pinout and thermal pad connectivity before substitution.
