LP3470M5X-4.63/NOPB

Supervisors Overview

The LP3470M5X-4.63/NOPB is an active-low reset IC from Texas Instruments featuring a fixed 4.63 V threshold with 1% accuracy. It operates within a supply voltage range up to 5.5 V and draws 16 µA of quiescent current. The device provides a 2 ms reset delay, adjustable via an external capacitor, and outputs an open-drain signal. It functions in the -20°C to +85°C temperature range using a SOT-23-5 package.

Supervisors Feature Summary

• Ultra-low power consumption suitable for battery-operated systems
• Fixed precise reset threshold voltage for reliable monitoring
• Programmable reset timeout period using external capacitance
• Compact surface-mount packaging for space-constrained designs

Supervisors Applications

• Portable electronic devices requiring low standby current
• Battery-powered equipment needing voltage supervision
• Embedded systems utilizing microcontrollers or processors
• Consumer electronics with strict power management requirements

Supervisors Procurement Notes

Verify the specific suffix 'X' indicates tape-and-reel packaging configuration distinct from standard tube variants. Confirm RoHS compliance status as documentation may vary by production batch. Ensure the 4.63 V threshold matches the target system's brown-out detection requirements precisely before integration.

Supervisors Selection Notes

Select this component when a fixed 4.63 V threshold is required rather than programmable options. The SOT-23-5 package suits applications with limited board space. Consider the 16 µA quiescent current for energy efficiency needs. Verify that the 2 ms base delay meets the system's startup timing constraints without excessive external components.

Supervisors Part Context

This part belongs to the LP3470 family of tiny power-on reset circuits designed for voltage supervision. It serves as a specialized variant within Texas Instruments' portfolio for monitoring single-input power rails. The device complements other supervisors by offering a balance of precision and minimal power draw in a small footprint.

Supervisors Replacement Considerations

LP3470M5-4.63/NOPB offers equivalent electrical specifications but differs in packaging format.
