LP3470IM5-2.83/NOPB

Supervisors Overview

The LP3470IM5-2.83/NOPB is a voltage supervisory circuit manufactured by Texas Instruments, categorized under power management ICs. It features an active-low open-drain reset output with a programmable delay time of 2 ms. The device monitors a single input channel and operates within a maximum supply voltage of 5.5 V. It utilizes a SOT-23-5 surface-mount package and supports a threshold voltage of 2.83 V. The component functions as a tiny power-on reset circuit without manual reset or watchdog timer capabilities.

Supervisors Feature Summary

• Provides active-low reset signal generation based on monitored voltage levels
• Features programmable reset delay timing for system synchronization
• Utilizes compact SOT-23-5 surface-mount packaging for space-constrained designs

Supervisors Applications

• Power-on reset monitoring in embedded systems
• Voltage supervision for microcontroller power rails
• System reset generation in portable electronic devices

Supervisors Procurement Notes

Verify the manufacturer designation carefully, as this component is produced by Texas Instruments despite historical brand associations. Confirm the specific suffix /NOPB indicates lead-free compliance and check current lifecycle status, as similar variants may be marked as Not Recommended for New Designs (NRND). Ensure the 2.83V threshold matches the target application requirements before procurement.

Supervisors Selection Notes

Select this part when a precise 2.83V threshold is required for low-voltage monitoring applications. Consider the 2ms programmable delay to accommodate power-up stabilization times. Verify that the active-low open-drain output configuration aligns with the downstream logic interface requirements and pull-up resistor availability in the design.

Supervisors Part Context

This component belongs to the LP3470 series of supervisory circuits from Texas Instruments. It is functionally related to other variants such as LP3470IM5-2.93/NOPB and LP3470IM5-3.08/NOPB, differing primarily in the specific reset threshold voltage. The series provides simple power-on reset functionality in a small footprint suitable for modern consumer electronics.

Supervisors Replacement Considerations

Direct substitutes include LP3470IM5-2.83/NO. Alternative threshold variants like LP3470IM5-2.93/NOPB may serve if voltage tolerance permits.
