TPS3831K50DQNT

Supervisors Overview

The TPS3831K50DQNT is an ultralow power supply voltage supervisor from Texas Instruments, designed for battery-powered and portable equipment. It features a fixed output threshold of 5.0 V with 1.6% accuracy. The device operates within a supply voltage range of 600 mV to 6.5 V and consumes only 150 nA of quiescent current. It provides a manual reset input and an active-low push-pull output with a 200 ms reset delay. Operating temperatures range from -40°C to +85°C in a compact 4-X2SON package.

Supervisors Feature Summary

• Ultra-low 150 nA current consumption ideal for energy-constrained applications
• Fixed 5.0 V monitoring threshold with high precision
• Manual reset capability for system control flexibility
• Compact 4-X2SON surface-mount packaging

Supervisors Applications

• Portable electronic devices
• Battery-powered instrumentation
• Industrial metering systems
• Low-power embedded controllers

Supervisors Procurement Notes

Verify the specific suffix K50 confirms the 5.0 V threshold during procurement. Ensure the DQNT designation matches the required X2SON-4 package and tape-and-reel configuration. Confirm RoHS compliance status aligns with project requirements before finalizing orders.

Supervisors Selection Notes

Select this component when a fixed 5.0 V supervision level is required with minimal standby current impact. The manual reset feature suits designs needing external trigger control. Verify that the 200 ms delay meets system startup timing constraints and that the 6.5 V maximum rating accommodates peak supply voltages.

Supervisors Part Context

This part belongs to the TPS383x family of voltage supervisors, characterized by ultra-low power consumption. It serves as a dedicated monitor for single-rail systems where power efficiency is critical. The series supports various threshold options to accommodate different logic levels and battery chemistries.

Supervisors Replacement Considerations

TPS3839K50DQNT is a parameter-equivalent alternative within the same family offering similar functionality.
