LM3880MFX-1AD/NOPB

Power Supply Controllers, Monitors Overview

The LM3880MFX-1AD/NOPB is a supervisory circuit manufactured by Texas Instruments, functioning as a simple power sequencer. It monitors three input rails and operates within a supply voltage range up to 5.5 V. The device is housed in a SOT-23-6 surface-mount package. It supports an operating temperature range from -40°C to +125°C. The component does not include manual reset or watchdog timer features.

Power Supply Controllers, Monitors Feature Summary

• Monitors three independent input rails for power sequencing applications
• Provides fixed time delay functionality for controlled power-up sequences
• Operates with open-drain outputs for flexible interface compatibility

Power Supply Controllers, Monitors Applications

• Power sequencing in multi-rail embedded systems
• Supervision of voltage rails in industrial control units
• Monitoring power integrity in automotive electronic modules

Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix '1AD' against the manufacturer's official datasheet to confirm the exact threshold voltages and timing characteristics. Ensure the SOT-23-6 package footprint matches the design requirements. Confirm RoHS compliance status through the latest production documentation before finalizing procurement specifications.

Power Supply Controllers, Monitors Selection Notes

Select this component when a three-rail power sequence is required without manual reset capabilities. The wide operating temperature range suits harsh environments. Verify that the maximum supply voltage of 5.5 V aligns with the system's power rail specifications. Consider the absence of a watchdog timer if fault recovery monitoring is necessary.

Power Supply Controllers, Monitors Part Context

This part belongs to the LM3880 series of simple power sequencers from Texas Instruments. The series provides basic supervision for multiple voltage rails. The MFX suffix indicates the specific tape-and-reel packaging format. The NOPB designation confirms lead-free and halogen-free construction compliant with environmental standards.

Power Supply Controllers, Monitors Replacement Considerations

The LM3880QMF-1AF/NOPB is an automotive-grade alternative within the same family. Both share the SOT-23-6 package and three-input monitoring capability. Verify threshold voltage tolerances and AEC-Q100 qualification requirements when substituting.
