LP3470IM5X-2.93/NOPB

Supervisors Overview

The LP3470IM5X-2.93/NOPB is a voltage supervisory circuit manufactured by Texas Instruments, designed to monitor power supply integrity in electronic systems. It operates within a maximum supply voltage of 5.5 V and features a precise reset threshold voltage of 2.93 V with an accuracy of 1%. The device provides an active-low, open-drain output signal that triggers when the monitored voltage drops below the specified threshold. It incorporates a fixed reset delay time of 2 ms to ensure stable system initialization. The component is housed in a compact SOT-23-5 surface-mount package and supports operation across a temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Provides precise voltage supervision with 1% threshold accuracy
• Features active-low open-drain output for direct logic interfacing
• Includes fixed 2 ms reset delay for reliable power-on sequencing

Supervisors Applications

• Portable battery-powered equipment requiring low quiescent current
• Microcontroller and digital logic power supply monitoring
• Embedded systems needing reliable power-on reset signals

Supervisors Procurement Notes

Verify the specific suffix 'X' indicates reel packaging configuration as per manufacturer standards. Confirm RoHS compliance status matches current regulatory requirements. Ensure the operating temperature range aligns with your environmental specifications. Cross-reference the exact part number against the latest Texas Instruments datasheet to confirm pinout and electrical characteristics remain unchanged.

Supervisors Selection Notes

Select this component when a fixed 2.93 V threshold is required for single-input voltage monitoring. The SOT-23-5 package suits space-constrained designs. Consider the 16 uA typical operating current for battery efficiency. Verify that the active-low open-drain output meets the input requirements of the downstream logic or microcontroller reset pin without additional pull-up components if compatible.

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 rail levels. The LP3470 series is characterized by ultra-low power consumption and high precision, making it suitable for portable applications where battery life is critical. The device simplifies design by integrating reset generation without external timing components for the standard delay.

Supervisors Replacement Considerations

Direct substitutes include LP3470IM5-2.93/NOPB. Parameter-equivalent alternatives may include other LP3470 variants with matching thresholds. Verify pin compatibility and electrical specs before substitution.
