TPS3839G12DQNR

Supervisors Overview

The TPS3839G12DQNR is a supply voltage supervisor manufactured by Texas Instruments, designed to monitor system power integrity. It features a fixed reset threshold voltage of 1.1V and provides a push-pull/totem pole output with an active-low reset signal. The device ensures reliable operation through a minimum reset timeout of 120ms. It operates within a temperature range of -40°C to 85°C and is housed in a compact 4-X2SON (1x1) surface-mount package.

Supervisors Feature Summary

• Monitors single supply voltage with a fixed 1.1V threshold
• Provides active-low reset signal via push-pull output
• Ensures stable startup with 120ms minimum reset timeout

Supervisors Applications

• Embedded system power management
• Microcontroller reset circuitry
• Portable electronic devices

Supervisors Procurement Notes

Verify the complete part number including suffixes to ensure correct threshold voltage and package configuration. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Cross-reference datasheet specifications against application needs before procurement.

Supervisors Selection Notes

Select this component when a fixed 1.1V supervision threshold is required for low-voltage systems. Consider the 4-X2SON package for space-constrained designs. Ensure the 120ms timeout meets system startup timing requirements. Verify operating temperature range compatibility with the deployment environment.
