2U3837J25QDBVRG4Q1

Overview

The Texas Instruments 2U3837J25QDBVRG4Q1 is an automotive-grade voltage supervisory circuit designed for critical system monitoring. It operates within a supply voltage range up to 6 V and features a fixed threshold of 2.25 V. The device provides a manual reset input and delivers an active low, push-pull output with a 200 ms reset delay. Packaged in a compact SOT-23-5 surface-mount case, it supports operation from -40°C to +125°C. Certified under AEC-Q100 standards, this component ensures reliable performance in demanding automotive environments.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards
• Manual reset capability for controlled system recovery
• Active low push-pull output configuration
• Compact SOT-23-5 surface-mount packaging

Applications

• Automotive electronic control unit (ECU) power monitoring
• Battery voltage supervision in vehicle systems
• Microcontroller reset management in automotive networks

Procurement Notes

Verify the specific suffix G4Q1 against official Texas Instruments documentation to confirm package type and tape-and-reel specifications. Confirm current product status as obsolete or lifecycle changes may affect long-term availability. Ensure compatibility with existing PCB footprints and thermal requirements before integration.

Selection Notes

Select this component when AEC-Q100 certification is mandatory for automotive applications. The fixed 2.25 V threshold suits systems requiring precise voltage monitoring without adjustable options. Consider the manual reset feature if external control over the reset state is required. Verify that the SOT-23-5 package fits the design constraints.

Part Context

This part belongs to the TPS3836/TPS3837 family of nano-power supervisors from Texas Instruments. These devices are engineered for low standby current consumption while maintaining high accuracy. The family includes variants with different thresholds and reset delays, tailored for various automotive and industrial monitoring needs.

Replacement Considerations

Check for direct cross-reference parts within the TPS383x series. Verify equivalent threshold voltages and reset delays. Ensure any substitute maintains AEC-Q100 qualification and compatible pinout.
