LP3470M5X-3.08

Supervisors Overview

The LP3470M5X-3.08 is a voltage supervisory circuit manufactured by Texas Instruments, designed for monitoring single-input power rails. It operates within a maximum supply voltage of 5.5 V and features an active-low, open-drain output type. The device provides a precise reset threshold voltage of 3.08 V with 1% accuracy. It includes a programmable reset delay time of 2 ms and functions without manual reset or watchdog timer capabilities. The component supports surface mount installation in an SOT-23-5 package and operates across a temperature range from -20°C to +85°C.

Supervisors Feature Summary

• Provides active-low reset signaling via an open-drain output interface
• Features a fixed 3.08 V reset threshold with high precision accuracy
• Includes a programmable reset delay timer for controlled startup sequencing
• Designed for low-power applications with minimal quiescent current consumption

Supervisors Applications

• Power-on reset generation for microprocessors and digital logic circuits
• Voltage supervision for battery-powered portable devices
• Monitoring of single-rail power supplies in embedded systems
• Reset signal generation for memory and storage components

Supervisors Procurement Notes

Verify the exact suffix configuration when ordering, as variations such as NOPB indicate specific compliance standards. Confirm availability status, as this component may be classified as not recommended for new designs. Ensure compatibility with existing PCB footprints, specifically the SOT-23-5 package dimensions. Cross-reference datasheet revisions to confirm electrical characteristics match design requirements before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when a fixed 3.08 V threshold is required for single-channel voltage monitoring. Consider the SOT-23-5 package size for space-constrained designs. Evaluate the 2 ms reset delay against system startup timing requirements. Verify that the active-low open-drain output aligns with the input requirements of the downstream logic or controller being monitored.

Supervisors Part Context

This part belongs to the LP3470 family of tiny power-on-reset circuits from Texas Instruments. The family offers various threshold voltages to accommodate different supply rail standards. The M5X designation indicates a specific tape-and-reel packaging format optimized for automated assembly processes. These devices are engineered for compact electronic applications requiring reliable voltage supervision.

Supervisors Replacement Considerations

Direct substitutes include LP3470IM5-3.08/NOPB and LP3470A308DBVR. Verify pinout compatibility and electrical specifications before substitution. Check if alternative parts offer improved thermal performance or extended temperature ranges suitable for the target application environment.
