TPS3106K33DBVRG4

Supervisors Overview

The TPS3106K33DBVRG4 is a voltage supervisory circuit manufactured by Texas Instruments, designed for monitoring supply voltages in low-power applications. It features an ultra-low supply current of 40 µA and operates within a supply voltage range of 0.4 V to 3.6 V. The device provides a fixed reset threshold accuracy of 0.75% and includes a manual reset input. It utilizes an active-low, open-drain output with a typical reset delay time of 130 ms. The component is housed in a SOT-23-6 package and supports operation across a temperature range of -40°C to +125°C.

Supervisors Feature Summary

• Ultra-low supply current consumption for extended battery life
• Fixed threshold voltage supervision with high accuracy
• Manual reset capability for system control flexibility

Supervisors Applications

• Portable medical devices requiring reliable power monitoring
• Battery-operated consumer electronics
• Industrial embedded systems with strict power constraints

Supervisors Procurement Notes

Verify the specific suffix G4 indicates lead-free compliance and RoHS standards as per Texas Instruments documentation. Confirm availability status through official channels, as distribution may vary by region. Ensure the ordering part number matches the exact package and temperature grade requirements for your design. Cross-reference datasheet revisions to confirm pinout consistency if replacing older variants.

Supervisors Selection Notes

Select this component when a fixed voltage threshold is sufficient for the application's power rail. The 40 µA quiescent current makes it suitable for energy-sensitive designs where standby power is critical. Consider the 130 ms reset delay to ensure stable power before system initialization. Verify that the open-drain output interface aligns with the downstream logic requirements.

Supervisors Part Context

This device belongs to the TPS3106 family of ultra-low supply current voltage supervisory circuits from Texas Instruments. The family offers various threshold options and packaging configurations to suit different monitoring needs. The K33 variant specifically targets 3.3 V supply rails common in modern digital logic systems.

Supervisors Replacement Considerations

Check for TPS3106K33DBVR as a potential predecessor or alternative within the same series. Ensure any substitute maintains the SOT-23-6 package and compatible electrical characteristics.
