2U3837K33QDBVRG4Q1

Overview

The TPS3837K33QDBVRG4Q1 is a single-channel voltage supervisor IC from Texas Instruments, designed for automotive applications. It operates within a supply voltage range up to 6 V and features a fixed threshold of 2.93 V. The device provides a push-pull or totem pole output in an SOT-23-5 package. It is AEC-Q100 qualified and functions across a temperature range of -40°C to 125°C.

Feature Summary

• Automotive-grade qualification ensuring reliability in vehicle environments
• Single-channel monitoring with fixed voltage threshold detection
• Push-pull output configuration for direct interface compatibility

Applications

• Automotive electronic control unit power supervision
• Battery voltage monitoring in vehicle systems
• Microcontroller reset generation in automotive modules

Procurement Notes

Verify the exact suffix G4 indicates lead-free RoHS compliance and specific tape/reel packaging details. Confirm current availability status as some sources indicate obsolete status. Ensure the K33 variant matches the required 2.93V threshold for your design. Cross-reference the manufacturer part number with official TI documentation to avoid counterfeit components.

Selection Notes

Select this component when a single-channel supervisor with push-pull output is required for automotive designs. The fixed 2.93V threshold suits 3.3V system monitoring. Consider the SOT-23-5 package size constraints. Verify thermal performance within the specified operating temperature range for your application environment.

Part Context

This part belongs to the TPS383x family of voltage supervisors. It shares similarities with TPS3836 and TPS3838 but differs in output type and reset delay characteristics. The Q1 designation confirms automotive grade classification. The G4 suffix typically denotes environmental compliance updates.

Replacement Considerations

Direct substitutes include TPS3836K33QDBVRQ1 and TPS3838K33QDBVRQ1. Note that TPS3836 offers open-drain output while TPS3838 has manual reset capability. Verify pinout compatibility and electrical parameter alignment before substitution.
