LP3470IM5-4.8/NOPB

Supervisors Overview

The LP3470IM5-4.8/NOPB is a voltage supervisory circuit manufactured by Texas Instruments, designed for monitoring single power supply 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 fixed reset threshold voltage of 4.8 V with a reset delay time of 2 ms. It 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 via open-drain output
• Features fixed 1% accuracy reset threshold voltage
• Includes programmable reset delay timer functionality

Supervisors Applications

• Portable equipment power management
• Microprocessor system supervision
• Battery-powered device protection

Supervisors Procurement Notes

Verify the specific suffix and tolerance against official datasheets before procurement. Confirm package integrity and RoHS compliance status. Check for obsolescence notices or lifecycle changes. Ensure compatibility with existing board layouts and thermal requirements. Validate supplier authenticity through authorized channels.

Supervisors Selection Notes

Select this component when a fixed 4.8V threshold is required for single-rail monitoring. Consider the SOT-23-5 package size constraints. Evaluate the 2ms delay against system startup timing needs. Compare operating temperature ranges with environmental conditions. Verify output drive capabilities match downstream logic inputs.

Supervisors Part Context

This part belongs to the LP3470 family of tiny power-on-reset circuits. It serves as a dedicated supervisor for ensuring stable operation in embedded systems. The series offers various threshold options to accommodate different voltage rails. It integrates essential reset generation without requiring external components.

Supervisors Replacement Considerations

LP3470IM5-4.8/NOPB may be replaced by other LP3470 variants with compatible thresholds. Direct substitutes include parts with identical pinouts and electrical characteristics. Verify functional equivalence before substitution.
