2T28-33QDBVRG4Q1

Overview

The TPS3825-33QDBVRQ1 is an automotive-grade processor supervisory circuit in a 5-pin SOT-23 package. It features a fixed voltage threshold of 2.93V and operates within a supply voltage range of 1.1V to 5.5V. The device provides manual reset capability with an active-low, push-pull output driver. It functions reliably across an extended temperature range from -40°C to +125°C, ensuring robust system monitoring for critical applications.

Feature Summary

• Integrated watchdog timer functionality for automated system health monitoring
• Manual reset input allows external control over the reset state
• Active-low push-pull output driver ensures strong signal integrity

Applications

• Automotive electronic control units requiring AEC-Q100 compliance
• Microprocessor power supply monitoring systems
• Embedded controllers needing watchdog timer protection

Procurement Notes

Verify the component marking 'PDIQ' on the physical device to confirm authenticity. Ensure the order specifies the Q1 suffix for automotive qualification. Cross-reference the full part number TPS3825-33QDBVRQ1 with official Texas Instruments documentation to validate the specific revision and packaging details before finalizing procurement.

Selection Notes

Select this component when an automotive-rated supervisor with integrated watchdog functionality is required. The fixed 2.93V threshold suits 3V logic systems. The SOT-23-5 package offers space efficiency. Verify that the manual reset feature aligns with the system design requirements for external reset control capabilities.

Part Context

This part belongs to the TPS3825 family of processor supervisors designed for automotive environments. It integrates voltage monitoring and watchdog timer functions into a single compact solution. The Q1 designation indicates compliance with automotive quality standards, distinguishing it from commercial-grade variants in the same functional family.

Replacement Considerations

The variant 2T28-33QDBVRG4Q1 shares identical electrical specifications but may differ in manufacturing lot or specific revision code. Verify pinout compatibility and package dimensions before substitution. Confirm that the G4 suffix does not alter the functional behavior or automotive qualification status.
