LP3470M5-2.63/NOPB

Supervisors Overview

The LP3470M5-2.63/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. The device provides a precise reset threshold of 2.63 V with 1% accuracy. It includes a programmable reset delay time of 2 ms, adjustable via an external capacitor. The component is housed in a SOT-23-5 surface-mount package and supports operation across a temperature range from -20°C to +85°C.

Supervisors Feature Summary

• Provides active-low reset signal when monitored voltage drops below the specified threshold
• Features programmable reset delay controlled by an external capacitor
• Offers high precision reset threshold accuracy for reliable power supervision

Supervisors Applications

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

Supervisors Procurement Notes

Verify the exact part number including suffixes such as NOPB and M5 to ensure correct threshold voltage and package type. Confirm operational temperature range requirements against the specific variant specifications. Check current lifecycle status as some variants may be marked as not recommended for new designs. Ensure compatibility with existing PCB footprint and soldering processes for SOT-23-5 packages.

Supervisors Selection Notes

Select this component when a fixed low-voltage threshold near 2.63 V is required for system reset logic. Consider the 2 ms default delay and external capacitor capability for timing adjustments. Evaluate the -20°C to +85°C industrial temperature range suitability for the target environment. Compare against other LP3470 variants if different threshold voltages or extended temperature ranges are needed.

Supervisors Part Context

This part belongs to the LP3470 family of ultra-low-power voltage supervisors from Texas Instruments. The family offers various fixed threshold options and pin-compatible packages. The LP3470 series is designed for applications requiring precise power management and reliable reset generation in compact form factors.

Supervisors Replacement Considerations

Check for direct pin-to-pin replacements within the LP3470 family with different threshold voltages. Verify if upgraded variants like LP3470A offer improved performance or availability. Ensure substitute parts match the SOT-23-5 package and electrical characteristics.
