2U3824-50QDBVRG4Q1

Overview

The Texas Instruments 2U3824-50QDBVRG4Q1 is a single-channel processor supervisory circuit designed for automotive applications. It operates within a supply voltage range of up to 6 V and features a manual reset input. The device provides an active low, push-pull output with a reset delay time of 200 ms. It is housed in a SOT-23-5 surface-mount package and supports operation at temperatures down to -40°C. This component serves as a voltage supervisor to monitor system power integrity.

Feature Summary

• Single-channel voltage supervision for automotive-grade systems
• Manual reset capability with active low push-pull output
• Compact SOT-23-5 surface-mount packaging

Applications

• Automotive electronic control unit (ECU) power monitoring
• Processor system reset management
• Voltage supervision in automotive-grade embedded systems

Procurement Notes

Verify the exact part number against official Texas Instruments documentation before procurement. Confirm that the QDBVRG4 suffix aligns with required automotive qualification standards. Check current availability status as distribution channels may vary. Ensure compatibility with existing board layouts using the SOT-23-5 footprint. Validate temperature ratings against specific application environmental requirements.

Selection Notes

Select this component when a single-channel supervisor with manual reset functionality is required for automotive environments. Consider the 200 ms reset delay and active low output characteristics during circuit design. Evaluate the SOT-23-5 package size constraints against available board space. Ensure the input voltage range meets the specific system power rail specifications.

Part Context

This component belongs to the Texas Instruments family of processor supervisory circuits tailored for automotive use. It shares the SOT-23-5 package form factor common across many TI voltage supervisors. The 'Q' designation typically indicates automotive qualification, while 'G4' often refers to lead-free and RoHS compliance attributes in TI nomenclature.
