LP3470M5-3.08/NOPB

Supervisors Overview

The LP3470M5-3.08/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 a precise reset threshold voltage of 3.08 V with 1% accuracy. The device utilizes an active-low, open-drain output configuration to signal reset conditions. It includes a fixed reset delay time of 2 ms to ensure stable power-up sequences. The component is housed in a compact SOT-23-5 surface-mount package, suitable for space-constrained applications.

Supervisors Feature Summary

• Provides accurate voltage supervision with a 1% reset threshold tolerance
• Features an active-low open-drain output for direct interface with digital logic
• Includes a fixed 2 ms reset delay to prevent premature system activation during power transitions

Supervisors Applications

• Portable battery-powered devices requiring low quiescent current
• Embedded systems needing reliable power-on reset signals
• Microcontroller and FPGA power management circuits

Supervisors Procurement Notes

Verify the specific suffix and package type against the latest manufacturer datasheet to ensure compatibility with design requirements. Confirm RoHS compliance status as indicated in official documentation. Check for obsolescence notices or recommended new design alternatives prior to final procurement decisions.

Supervisors Selection Notes

Select this component when a fixed 3.08 V threshold and 2 ms delay are required. Ensure the operating temperature range meets application needs. Consider pinout compatibility if replacing existing designs. Verify that the open-drain output suits the downstream logic level requirements without additional pull-up components.

Supervisors Part Context

This part belongs to the LP3470 family of ultra-low-power voltage supervisors from Texas Instruments. The family offers various threshold voltages and packaging options.
