LP3470M5X-3.08/NOPB

Supervisors Overview

The LP3470M5X-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 of 3.08 V with an accuracy of 1%. The device provides an active-low, open-drain output and includes a fixed reset delay time of 2 ms. It consumes a typical operating supply current of 16 uA and supports power-failure detection. The component is housed in a SOT-23-5 package and functions without manual reset or watchdog timer capabilities.

Supervisors Feature Summary

• Provides active-low open-drain reset signaling when monitored voltage drops below the specified threshold.
• Features programmable reset timeout duration using an external capacitor connected to the delay pin.
• Includes power-failure detection capability to monitor supply voltage stability.
• Operates with ultra-low quiescent current suitable for battery-powered applications.

Supervisors Applications

• Portable consumer electronics requiring low standby current
• Battery-operated devices needing reliable power supervision
• Embedded systems utilizing single-supply voltage monitoring

Supervisors Procurement Notes

Verify the exact suffix configuration against the manufacturer's datasheet to ensure correct threshold voltage and package type. Confirm RoHS compliance status as indicated in official documentation. Check for obsolescence notices or recommended new designations from Texas Instruments prior to procurement. Ensure the ordering part number matches the specific electrical parameters required for the target application.

Supervisors Selection Notes

Select this component when a fixed 3.08 V threshold is required for power monitoring. Consider the 16 uA supply current for low-power designs. Verify that the SOT-23-5 package fits the PCB layout constraints. Ensure the external capacitor selection aligns with the desired reset delay timing requirements specified in the technical data.

Supervisors Part Context

This part belongs to the LP3470 family of tiny power-on reset circuits from Texas Instruments. The series offers various threshold voltages and packaging options.
