2U3838L30QDBVRG4Q1

Overview

The TPS3838L30QDBVRG4Q1 is a NanoPower supervisory circuit designed for automotive applications. It operates within a supply voltage range of up to 6 V and features a fixed reset threshold voltage of 2.64 V. The device provides an active-low open-drain output with a manual reset function. It supports a minimum reset delay time of 100 ms and functions reliably across an extended temperature range from -40°C to +125°C. Packaged in a compact SOT-23-5 format, it ensures precise power management monitoring.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 standards
• Ultra-low quiescent current consumption for battery efficiency
• Manual reset capability for system control flexibility

Applications

• Automotive electronic control unit (ECU) power monitoring
• Battery backup system supervision
• Microprocessor reset circuitry in harsh environments

Procurement Notes

Verify the specific suffix G4 indicates lead-free and RoHS compliance status against the latest manufacturer documentation. Confirm that the Q1 designation strictly aligns with your project's automotive reliability requirements. Ensure the SOT-23-5 package dimensions match your PCB footprint constraints precisely before finalizing procurement orders.

Selection Notes

Select this component when fixed threshold accuracy at 2.64 V is required without external resistor networks. It is suitable for designs needing manual reset intervention alongside automatic power-on reset functionality. Consider the SOT-23-5 package size if board space is limited while maintaining automotive thermal performance specifications.

Part Context

This part belongs to the TPS3838 family of NanoPower Supervisory Circuits from Texas Instruments. It shares architectural similarities with other members like the TPS3838E18 but differs in threshold voltage and automotive qualification. The family focuses on low-power monitoring solutions for critical systems requiring high reliability.
