LP3470M5-3.65/NOPB

Supervisors Overview

The LP3470M5-3.65/NOPB is a micropower voltage supervisory circuit manufactured by Texas Instruments, designed to monitor system voltages with high precision. It features an active-low open-drain output and operates within a supply voltage range up to 5.5 V. The device provides a fixed reset threshold of 3.65 V with 1% accuracy over temperature. Key electrical parameters include a maximum reset delay time of 2 ms and a typical quiescent current of 300 µA. It is housed in a compact SOT-23-5 package and supports surface-mount installation.

Supervisors Feature Summary

• Micropower voltage supervision with 1% threshold accuracy over temperature
• Active-low open-drain output for direct interface with digital logic
• Compact SOT-23-5 surface-mount packaging for space-constrained designs

Supervisors Applications

• Portable battery-powered equipment requiring low standby current
• Embedded systems needing reliable power-on reset sequencing
• Microcontroller-based circuits requiring voltage monitoring

Supervisors Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free compliance and RoHS adherence as per Texas Instruments standards. Confirm the 'M5' designation corresponds to the SOT-23-5 package variant. Check the lifecycle status, as this component may be marked as Not Recommended for New Designs (NRND). Ensure the 3.65 V threshold matches the target supply rail requirements before procurement.

Supervisors Selection Notes

Select this part when a fixed 3.65 V threshold is required for voltage monitoring. The SOT-23-5 package suits applications with limited board space. Consider the 2 ms reset delay for timing-sensitive microcontroller resets. Verify that the 5.5 V maximum supply voltage aligns with the system's operating range. Evaluate the 300 µA quiescent current against battery life requirements.

Supervisors Part Context

The LP3470 series comprises micropower supervisors from Texas Instruments. This specific model offers a fixed threshold option, simplifying design compared to programmable variants. It belongs to the broader family of voltage supervisors used for system reliability. The M5 suffix denotes the small outline transistor package configuration.
