LP3470IM5-3.08

Supervisors Overview

The LP3470IM5-3.08 is a voltage supervisory circuit manufactured by Texas Instruments, designed for monitoring power supply integrity in electronic systems. It features an active-low open-drain output and operates within a maximum supply voltage of 5.5 V. The device provides a precise reset threshold of 3.08 V with 1% accuracy, ensuring reliable detection of under-voltage conditions. It includes a fixed reset delay time of 2 ms to prevent false triggering during power-up transients. The component is housed in a compact SOT-23-5 surface-mount package and supports operation across a temperature range of -40°C to +85°C.

Supervisors Procurement Notes

Verify the specific suffix and revision level when sourcing, as the LP3470IM5-3.08 may be marked as Not Recommended for New Designs (NRND). Confirm availability of direct replacements such as the LP3470IM5-3.08/NOPB or the upgraded LP3470A series if long-term supply assurance is required. Ensure that the procurement channel provides genuine components with valid traceability documentation to avoid counterfeit risks associated with obsolete part numbers.

Supervisors Selection Notes

Select this component when a fixed 3.08 V threshold is required for system supervision. Consider the LP3470A series for enhanced performance or updated manufacturing status. Evaluate the external capacitor requirements for the reset delay timing against board space constraints. Verify that the open-drain output configuration aligns with the downstream logic voltage levels and pull-up resistor requirements of the target application design.
