LP3470IM5-2.63

Supervisors Overview

The LP3470IM5-2.63/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 type. The device monitors a single input with a precise threshold voltage of 2.63 V. It provides a fixed reset delay time of 2 ms to ensure stable system initialization. The component is housed in a compact SOT-23-5 package suitable for surface mount technology (SMD/SMT) applications. It functions without manual reset capabilities or watchdog timers.

Supervisors Feature Summary

• Provides active-low reset signal generation when monitored voltage drops below the specified threshold
• Features high accuracy reset threshold tolerance for reliable power supervision
• Utilizes external capacitor programming for adjustable reset delay timing

Supervisors Applications

• Portable battery-powered equipment requiring low quiescent current
• Microcontroller and digital logic power supply monitoring
• Embedded systems needing reliable power-on reset sequences

Supervisors Procurement Notes

Verify the exact suffix designation, as the base model may require specific trailing characters such as /NOPB for lead-free compliance. Confirm the operating temperature range matches your environmental requirements, as variants exist between -40°C to +85°C and other ranges. Ensure the package type corresponds to your PCB footprint specifications before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a fixed 2 ms delay is sufficient for the target application's startup sequence. Compare against the LP3470A series if higher voltage ratings up to 10 V or extended temperature ranges are required. Consider the LP3470IM5-2.63 variant specifically for 2.63 V threshold needs within the standard 5.5 V limit family.

Supervisors Part Context

This part belongs to the LP3470 family of ultra-low-power voltage supervisors from Texas Instruments. The family includes various threshold options and packaging styles, including the LP3470A series which offers enhanced performance characteristics. These devices are commonly used in consumer electronics and industrial control systems where space constraints and power efficiency are critical design factors.

Supervisors Replacement Considerations

Check for LP3470IM5-2.63/NOPB as the direct lead-free equivalent. Verify pin compatibility with other LP3470 variants sharing the SOT-23-5 package.
