2U3836J25QDBVRG4Q1

Overview

The Texas Instruments 2U3836J25QDBVRG4Q1 is a voltage supervisory circuit designed for automotive applications, featuring AEC-Q100 qualification. It operates within a supply voltage range up to 6 V and monitors a single input channel with a fixed threshold of 2.25 V. The device provides an active low, push-pull output and includes manual reset functionality with a 200 ms reset delay. It consumes 250 nA of operating current and maintains accuracy within 1.75%. The component functions reliably across a temperature range of -40°C to +125°C and is housed in a SOT-23-5 package.

Feature Summary

• Automotive-grade reliability with AEC-Q100 certification
• Ultra-low power consumption suitable for battery-backed systems
• Manual reset capability for system control flexibility

Applications

• Automotive electronic control units requiring voltage supervision
• Battery-powered automotive subsystems needing low quiescent current
• Systems requiring manual reset intervention during fault conditions

Procurement Notes

Verify the specific suffix G4Q1 against official Texas Instruments documentation to confirm manufacturing origin and compliance status. Confirm that the obsolete lifecycle status does not impact long-term availability requirements. Ensure the AEC-Q100 qualification aligns with target automotive application standards before procurement.

Selection Notes

Select this component when a fixed 2.25 V threshold is required for single-channel monitoring. Consider the manual reset feature if external control over the reset state is necessary. Verify that the SOT-23-5 package fits the design constraints and that the 250 nA current draw meets power budget requirements for the intended application.

Part Context

This part belongs to the TPS3836 family of nano-power supervisors from Texas Instruments. The '2U' prefix typically denotes a specific manufacturer or lot code variation, while the core TPS3836J25 designation indicates the functional specifications. The QDBVR suffix confirms the automotive grade, SOT-23-5 package, and reel/cut-tape packaging options available for this series.

Replacement Considerations

Direct substitutes include other TPS3836 variants with different thresholds, such as TPS3836K33QDBVRQ1 for a 2.93 V threshold. Non-automotive equivalents like TPS3836J25DBVR may be considered if AEC-Q100 qualification is not mandatory. Verify pin compatibility and electrical parameters before substitution.
