LP3470IM5-2.93/NOPB

Supervisors Overview

The LP3470IM5-2.93/NOPB 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 reset output. The device provides a precise threshold voltage of 2.93 V with 1% accuracy. It includes a fixed reset delay time of 2 ms to ensure stable system initialization. The component supports surface-mount installation in a SOT-23-5 package and functions across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides active-low reset signal generation based on monitored input voltage levels
• Features high precision threshold detection with specified accuracy tolerance
• Includes programmable reset delay functionality to manage startup sequences

Supervisors Applications

• Power-on reset circuits for embedded systems
• Voltage supervision for microcontroller power rails
• System integrity monitoring in portable electronics

Supervisors Procurement Notes

Verify the specific suffix designation to confirm the exact threshold voltage and package variant. Ensure compatibility with the target PCB footprint and thermal requirements. Confirm that the active-low open-drain output configuration aligns with the downstream logic interface requirements of the application design.

Supervisors Selection Notes

Select this component when a low-cost, single-channel voltage supervisor is required for critical power rail monitoring. Consider the 2.93 V threshold specifically for 3.3 V or similar nominal supply systems. Evaluate the SOT-23-5 package constraints against available board space and assembly capabilities.
