LP3470IM5X-3.08

Supervisors Overview

The LP3470IM5X-3.08 is a voltage supervisory circuit manufactured by Texas Instruments, designed for monitoring single-input power rails. It operates within a supply voltage range up to 5.5 V and features a fixed reset threshold of 3.08 V with 1% accuracy. The device provides an active-low, open-drain output and includes a 2 ms reset delay timer. It is housed in a compact SOT-23-5 surface-mount package and supports an operating temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Provides precise voltage supervision with a fixed 1% accurate threshold
• Delivers active-low open-drain reset signal generation
• Incorporates a programmable reset delay timer for stable startup
• Designed for low-power applications with minimal quiescent current

Supervisors Applications

• Portable electronic devices requiring reliable power management
• Battery-operated systems needing voltage level monitoring
• Embedded controllers requiring clean reset signals during power transitions
• Industrial equipment utilizing single-supply logic circuits

Supervisors Procurement Notes

Verify the specific suffix configuration when ordering, as variations such as /NOPB indicate lead-free compliance. Confirm availability status, as certain revisions may be marked as Not Recommended for New Designs (NRND). Ensure compatibility with existing PCB footprints and thermal requirements before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when a fixed 3.08 V threshold is required for system supervision. Consider the SOT-23-5 package size for space-constrained designs. Evaluate the 2 ms delay against system startup timing requirements. Verify that the active-low open-drain output aligns with the target microcontroller or logic interface specifications.

Supervisors Part Context

This part belongs to the LP3470 family of tiny power-on-reset circuits from Texas Instruments. The series offers various threshold voltages to accommodate different rail monitoring needs. The IM5X designation indicates industrial temperature grading and reel packaging, distinguishing it from commercial grade or tube-packaged variants within the same functional family.

Supervisors Replacement Considerations

Direct substitutes include LP3470IM5-3.08/NOPB. Alternative options may include LP3470A308DBVR for pin-compatible upgrades. Verify electrical parameters and package dimensions before swapping components to ensure system integrity.
