NCP380LMU20AATBG

Overview

The NCP380LMU20AATBG is a high-side power distribution switch from onsemi, designed for load driver applications. It features a single P-channel output with a maximum continuous current of 2.1 A and a fixed 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 exhibits a maximum on-resistance of 75 mOhms. Key timing parameters include a maximum turn-on time of 4 ms and a maximum idle time of 3 ms. It functions reliably across an operating temperature range of -40°C to +85°C and is housed in a compact uDFN-6 package.

Feature Summary

• Integrates overcurrent protection with fixed current limiting capabilities
• Provides controlled slew rate management to minimize inrush currents
• Includes status flag output for fault monitoring and system feedback

Applications

• High-side switching for peripheral loads in industrial equipment
• Power distribution units requiring precise current limiting
• Embedded systems managing multiple low-voltage subsystems

Procurement Notes

Verify the specific suffix configuration against the official datasheet to ensure compatibility with required current limits and enable logic levels. Confirm that the uDFN-6 thermal pad soldering process aligns with assembly guidelines. Cross-reference the RoHS compliance status and material declarations prior to final procurement to meet regulatory requirements.

Selection Notes

Select this component when a high-side switch with integrated current limiting and status reporting is required. Ensure the load current does not exceed the 2.1 A rating and that the control signal polarity matches the non-inverting input specification. Evaluate the thermal performance within the 75 mOhms resistance constraint for the target application environment.

Part Context

This part belongs to the NCP380 series of power switch ICs focused on power distribution. It complements other variants like the NCP380HMU20AATBG by offering specific electrical characteristics tailored for general-purpose load driving. The series emphasizes robust protection features and compact packaging for modern electronic designs.

Replacement Considerations

Direct substitutes within the same family include NCP380HMUAJAATBG and NCP380HMU21AATBG. Verify pinout compatibility and electrical parameter alignment before substitution.
