LP3470M5-4.63

Supervisors Overview

The LP3470M5-4.63 is an active-low reset integrated circuit manufactured by Texas Instruments, designed for power supply monitoring applications. It features a fixed reset threshold voltage of 4.63 V with 1% accuracy and a programmable delay time of 2 ms, adjustable via an external capacitor. The device operates within a supply voltage range up to 5.5 V and provides an open-drain output. It is housed in a 5-pin SOT-23 package and supports surface-mount installation. The component functions across a temperature range from -20°C to 85°C, with a quiescent current of 16 µA.

Supervisors Feature Summary

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm lot traceability and RoHS compliance status prior to procurement. Ensure storage conditions adhere to moisture sensitivity level requirements. Validate that the specific suffix matches design specifications. Review datasheet revisions for any functional updates affecting integration.

Supervisors Selection Notes

Select this component when a fixed 4.63 V threshold with 1% accuracy is required. Consider the 2 ms default delay and SOT-23-5 package constraints. Evaluate compatibility with system voltage rails not exceeding 5.5 V. Assess thermal performance within the -20°C to 85°C operating range. Compare against LP3470A series if higher voltage ratings or extended temperature ranges are needed.

Supervisors Part Context

Part of the LP3470 family of ultra-low-power voltage supervisors. Designed as a compact solution for space-constrained applications. Shares architectural similarities with other members like LP3470IM5-4.63/NOPB but differs in commercial temperature grading. Intended for general-purpose power monitoring where precise threshold detection is critical.

Supervisors Replacement Considerations

LP3470IM5-4.63/NOPB offers industrial temperature range (-40°C to 85°C) with identical electrical characteristics. Verify pinout compatibility and package dimensions before substitution. Check for any differences in delay time tolerances or leakage currents.
