Supervisors Procurement Notes

Verify the specific suffix /E5002423 against official Texas Instruments documentation to confirm its exact meaning, as standard datasheets typically list LP3470IM5-4.63/NOPB. Confirm current availability status, as this part may be obsolete or not recommended for new designs. Ensure the supplier provides valid traceability and authenticity guarantees for electronic components.

Supervisors Selection Notes

Select this component when a precise 4.63 V reset threshold is required for voltage supervision. Consider the 1% accuracy specification for applications demanding tight voltage tolerance. Evaluate the SOT-23-5 package size constraints against available board space. Verify that the active low open-drain output aligns with the downstream logic interface requirements.

Supervisors Part Context

The LP3470 series comprises micropower voltage supervisors designed for portable electronics. These devices monitor supply voltages and generate a reset signal when thresholds are exceeded. The IM5 variant indicates a specific temperature grade and package type within the broader LP3470 family, offering reliability for industrial and commercial applications.

Supervisors Replacement Considerations

Consult official Texas Instruments substitution guides for verified alternatives. Standard equivalents may include other LP3470 variants with different threshold voltages or packages. Ensure any replacement matches the electrical characteristics and pinout compatibility.
