LP3470A308DBVR

Supervisors Overview

The LP3470A308DBVR is an ultra-low-power voltage supervisor from Texas Instruments designed to monitor a single power supply rail. It features a fixed reset threshold of 3.08 V with 1% accuracy and provides an active-low, open-drain output. The device supports programmable reset delay via an external capacitor on the RESET pin. It operates within a supply voltage range up to 10 V and is available in a compact SOT-23-5 package.

Supervisors Feature Summary

• Ultra-low quiescent current for extended battery life
• Fixed 1% accurate reset threshold at 3.08 V
• Programmable reset delay using external capacitor
• Active-low open-drain output compatible with various logic levels

Supervisors Applications

• Portable electronic devices requiring low standby current
• Battery-powered systems needing reliable power supervision
• Embedded controllers requiring precise voltage monitoring
• Industrial equipment operating in wide temperature ranges

Supervisors Procurement Notes

Verify the exact suffix DBVR confirms the tape-and-reel packaging format. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the design accounts for the specific 3.08 V threshold and required external timing capacitor values. Check for any obsolescence notices or recommended new design alternatives from Texas Instruments before finalizing procurement.

Supervisors Selection Notes

Select this component when a fixed 3.08 V threshold is required with high precision. Choose the DBVR variant for automated surface-mount assembly needs. Consider the LP3470A series for its improved accuracy over standard LP3470 parts. Evaluate the maximum operating voltage of 10 V against the system supply rails. Ensure the application can accommodate the external capacitor for delay programming.

Supervisors Part Context

This part belongs to the LP3470A family of ultra-low-power voltage supervisors. It serves as a direct upgrade to the original LP3470 with enhanced threshold accuracy. The device is intended for applications where power efficiency and space constraints are critical. It complements other Texas Instruments power management solutions for complete system protection.

Supervisors Replacement Considerations

Direct substitutes include LP3470M5-3.08/NOPB and LP3470IM5-3.08/NOPB. Verify pin compatibility and electrical specifications before substitution. The LP3470A series offers improved accuracy compared to the base LP3470 model.
