FT3001UMX

Supervisors Overview

The FT3001UMX is a reset timer integrated circuit manufactured by Fairchild Semiconductor, now under onsemi. It features a configurable delay time and provides system reset functionality with open-drain or push-pull outputs. The device operates within a temperature range of -40°C to +85°C and is housed in a compact 10-UMLP (1.8x1.4mm) surface-mount package.

Supervisors Feature Summary

• Configurable reset delay timing for flexible system initialization requirements
• Dual output configuration supporting both open-drain and push-pull modes
• Compact 10-pin ultra-miniature leadless package for space-constrained designs

Supervisors Applications

• Embedded systems requiring reliable power-on reset sequences
• Microcontroller-based hardware supervision circuits
• Industrial control units needing configurable startup delays

Supervisors Procurement Notes

Verify component authenticity through authorized distributors due to discontinuation status. Check for obsolescence notices from onsemi. Confirm package marking and date codes against current production batches if sourcing from secondary markets. Ensure RoHS compliance documentation is available for regulatory adherence.

Supervisors Selection Notes

Select this component when a fixed-delay supervisor is insufficient and programmable timing is required. Compare pin compatibility with FT7511 series for simpler applications. Evaluate the UMLP footprint against PCB layout constraints. Consider the operating temperature range for environmental suitability in industrial or automotive contexts.

Supervisors Part Context

Part of the FT3001 family of reset timers, sharing functional similarities with FT3001MPX. Manufactured originally by Fairchild Semiconductor before acquisition by onsemi. Designed as a low-cost solution for basic system supervision tasks where precise voltage monitoring is less critical than timing reliability.

Supervisors Replacement Considerations

FT3001MPX offers identical functionality in a different package variant. FT7511 serves as a functional alternative with fixed delay characteristics. Verify pinout compatibility and electrical specifications before substitution.
