LP3470IM5X-4.00/NOPB

Supervisors Overview

The LP3470IM5X-4.00/NOPB is a voltage supervisory circuit manufactured by Texas Instruments, designed for monitoring power supply integrity in electronic systems. It operates within a maximum supply voltage of 5.5 V and features a precise reset threshold of 4.00 V with 1% accuracy. The device utilizes an active low, open-drain output to signal reset conditions when the monitored input drops below the threshold. It includes a programmable reset delay time of 2 ms, adjustable via an external capacitor, ensuring stable power-up sequences. The component supports surface mount installation in a compact SOT-23-5 package.

Supervisors Feature Summary

• Provides accurate voltage supervision with a fixed 1% reset threshold tolerance
• Features an active low open-drain output for flexible logic interfacing
• Includes a user-programmable reset delay controlled by an external capacitor

Supervisors Applications

• Power-on reset circuits for microprocessors and microcontrollers
• Voltage monitoring for battery-powered portable devices
• Supervisory circuits in embedded system power management

Supervisors Procurement Notes

Verify the exact suffix and manufacturer part number against official Texas Instruments documentation to ensure compatibility. Confirm RoHS compliance status and lead times through authorized distributors. Check for obsolescence notices or recommended replacements if sourcing for new designs. Ensure storage and handling procedures meet moisture sensitivity level requirements specified in the datasheet.

Supervisors Selection Notes

Select this component when a precise 4.00 V threshold is required for single-channel voltage monitoring. Consider the SOT-23-5 package size constraints and the need for an external capacitor for delay programming. Evaluate the active low open-drain output capability against the target system's input logic requirements. Verify that the operating temperature range meets the environmental conditions of the intended application.
