2U3836H30QDBVRG4Q1

Overview

The Texas Instruments 2U3836H30QDBVRG4Q1 is an automotive-grade voltage supervisory circuit designed for monitoring a single input. It operates within a maximum supply voltage of 6 V and features a threshold voltage of 2.79 V. The device provides an active low, push-pull output with manual reset capability. It includes a reset delay time of 200 ms and consumes a typical quiescent current of 250 nA. The component is housed in a SOT-23-5 package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Automotive qualified under AEC-Q100 standards for reliable operation in vehicle environments
• Ultra-low power consumption with 250 nA quiescent current for battery efficiency
• Manual reset functionality allows user-controlled system recovery
• Push-pull output stage ensures robust signal drive capability

Applications

• Automotive electronic control units requiring voltage supervision
• Battery-powered systems needing extended operational life
• Microprocessor reset circuits in harsh thermal environments

Procurement Notes

Verify the specific suffix G4Q1 against the manufacturer's latest documentation to confirm compliance with RoHS directives and material declarations. Ensure that the automotive grade qualification aligns with your project's reliability requirements. Cross-reference the part number with official distributors to confirm availability status, as this specific variant may be subject to lifecycle changes or obsolescence notices.

Selection Notes

Select this component when a single-channel voltage monitor with manual reset is required for automotive applications. The 2.79 V threshold suits systems operating near standard 3.3 V logic levels. Consider the 200 ms delay for stable startup sequences. Verify that the SOT-23-5 package fits the PCB layout constraints and that the 6 V maximum rating accommodates potential input transients.

Part Context

This part belongs to the TPS3836 family of voltage supervisors from Texas Instruments. The '2U' prefix indicates a specific manufacturing lot or revision code associated with the automotive grade version. It shares functional similarities with other parts in the series but is distinguished by its specific threshold voltage and packaging configuration tailored for space-constrained automotive designs.
