LP3470IM5-4.00/NOPB

Supervisors Overview

The LP3470IM5-4.00/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 an active low, open drain output type. The device provides a precise reset threshold voltage of 4.00 V with 1% accuracy. It includes a programmable reset delay time of 2 ms, adjustable via an external capacitor. The component supports surface mount installation in a SOT-23-5 package and functions reliably across a temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Provides active low reset signal generation when monitored voltage drops below the specified threshold
• Features high precision reset threshold accuracy for reliable power supervision
• Allows user-adjustable reset delay timing through external capacitor connection

Supervisors Applications

• Microprocessor system power supply monitoring
• Battery-powered device voltage supervision
• Embedded controller reset circuitry

Supervisors Procurement Notes

Verify the exact part number suffix against official Texas Instruments documentation to ensure correct threshold voltage and package configuration. Confirm RoHS compliance status as indicated in current datasheets. Check lifecycle status for availability and design-in recommendations before procurement planning.

Supervisors Selection Notes

Select this component when a fixed 4.00 V threshold with 1% accuracy is required for single-input voltage monitoring. Ensure the application environment stays within the specified operating temperature range. Verify that the open drain output interface matches the receiving logic requirements of the target system.

Supervisors Part Context

This device belongs to the LP3470 family of ultra-low-power voltage supervisors from Texas Instruments. The family offers various threshold options while maintaining consistent pinout and functional characteristics. The LP3470A variant provides enhanced performance with extended temperature ranges and higher voltage capabilities.

Supervisors Replacement Considerations

LP3470M5-4.00/NOPB serves as a direct equivalent with identical electrical specifications and pinout compatibility.
