LP3470IM5-2.63

Supervisors Overview

The LP3470IM5-2.63 is a voltage supervisor integrated circuit manufactured by Texas Instruments, formerly National Semiconductor. It operates within a supply voltage range of 1.2 V to 5.5 V and features a fixed reset threshold of 2.63 V with 1% accuracy. The device provides an active-low open-drain output and includes a programmable reset delay time ranging from 1 ms to 200 ms. It is housed in a compact SOT-23-5 package and supports an operating temperature range from -40°C to +85°C.

Supervisors Procurement Notes

Verify the manufacturer designation carefully, as National Semiconductor was acquired by Texas Instruments. Ensure the part number suffix matches the required threshold voltage and package type. Confirm RoHS compliance status and check for obsolescence notices or recommended new design alternatives before finalizing procurement specifications.

Supervisors Selection Notes

Select this component when a fixed 2.63 V threshold is required for single-supply monitoring. Consider the programmable delay feature if specific startup timing is necessary. Evaluate the SOT-23-5 footprint constraints against available board space. Compare quiescent current specifications against other supervisors in the LP3470 family to ensure optimal battery life performance.

Supervisors Part Context

This component belongs to the LP3470 family of tiny power-on-reset circuits originally developed by National Semiconductor and now produced by Texas Instruments. The family offers various fixed threshold voltages and programmable delay options. The IM5 suffix indicates the industrial temperature grade and SOT-23-5 packaging configuration.

Supervisors Replacement Considerations

Direct replacements include LP3470M5-2.63/NOPB and LP3470A263DBVR. Verify pin compatibility and electrical parameters such as threshold voltage and reset delay before substitution.
