TPS3825-50QDBVRQ1

Supervisors Overview

The TPS3825-50QDBVRQ1 is a Texas Instruments automotive-grade voltage supervisor circuit designed for reliable power management. It features a single monitoring channel with a fixed threshold of 4.55V and supports a supply voltage range from 1.1V to 5.5V. The device provides an active-low push-pull output and includes a manual reset function. It operates within a temperature range of -40°C to +125°C and is housed in a compact SOT-23-5 package.

Supervisors Feature Summary

• Includes a manual reset input for system control
• Features an active-low push-pull output driver
• Certified to AEC-Q100 standards for automotive applications

Supervisors Applications

• Automotive electronic systems requiring voltage supervision
• Microcontroller reset circuits in vehicle networks
• Power management units in automotive infotainment

Supervisors Procurement Notes

Verify the specific suffix 'Q1' confirms AEC-Q100 automotive qualification. Confirm the '50' designation matches the required 4.55V threshold. Check current production status as this part may be discontinued or subject to obsolescence notices. Ensure the SOT-23-5 package aligns with PCB footprint requirements.

Supervisors Selection Notes

Select this component when an active-low output and manual reset capability are required. Compare against TPS3820 if a watchdog timer is needed instead. Verify that the 4.55V threshold suits the target rail. Consider the SOT-23-5 package size constraints relative to available board space.

Supervisors Part Context

This part belongs to the TPS382x-Q1 family of simple supervisors. It shares the SOT-23-5 form factor with other variants like TPS3820 and TPS3828. The family focuses on basic voltage monitoring without complex timing features found in higher-end series.

Supervisors Replacement Considerations

TPS3825-50DBVR is a non-automotive equivalent. TPS3820-50QPDBVRQ1 offers similar voltage monitoring but lacks the manual reset feature.
