LP3470IM5X-2.93

Supervisors Overview

The LP3470IM5X-2.93/NOPB is a low-power voltage supervisor from Texas Instruments designed to monitor system power rails. It features an active-low, open-drain reset output triggered when the supply voltage drops below a precise 2.93 V threshold with 1% accuracy. The device includes a programmable reset delay controlled by an external capacitor and operates within a supply range up to 5.5 V. It is housed in a compact SOT-23-5 package and supports manual reset functionality.

Supervisors Feature Summary

• Provides precise voltage monitoring with 1% threshold accuracy
• Features active-low open-drain reset output for flexible interfacing
• Includes programmable reset delay via external capacitor
• Supports manual reset input for system control

Supervisors Applications

• Portable battery-powered equipment
• Wireless communication devices
• Handheld instruments
• Embedded systems requiring reliable power supervision

Supervisors Procurement Notes

Verify the specific suffix (e.g., NOPB) against the datasheet to confirm pinout and electrical characteristics. Confirm RoHS compliance status as required by your manufacturing standards. Ensure the SOT-23-5 package dimensions match your PCB footprint design constraints before finalizing procurement.

Supervisors Selection Notes

Select this component when a fixed 2.93 V threshold is required for single-supply monitoring. Consider the LP3470A series if lower quiescent current is needed, noting that it is pin-compatible but may have different electrical specifications. Evaluate the need for manual reset capability versus simpler power-on-reset-only applications.

Supervisors Part Context

This part belongs to the LP3470 family of ultra-low-power voltage supervisors. The family offers various threshold voltages to accommodate different logic levels and battery chemistries. The IM5X designation indicates the specific package type and thermal rating suitable for surface-mount assembly in space-constrained designs.

Supervisors Replacement Considerations

The LP3470A series is a pin-compatible alternative offering improved power efficiency. Verify that the replacement meets the specific 2.93 V threshold requirement and maintains compatibility with the existing reset delay circuitry.
