TLV809I50DBZT

Supervisors Overview

The TLV809I50DBZT is a single-channel voltage supervisory circuit manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and features a fixed threshold voltage of 4.55 V with an accuracy of 2.2%. The device provides an active-low, push-pull output and includes a reset delay time of 200 ms. It consumes 20 uA of operating current and functions reliably across a temperature range of -40°C to +85°C. Packaged in a compact SOT-23-3 surface-mount format, it lacks manual reset, watchdog timer, or battery backup switch capabilities.

Supervisors Feature Summary

• Provides active-low, push-pull output for reliable logic interfacing
• Ensures system stability through precise voltage monitoring with fixed threshold detection
• Optimized for low power consumption suitable for battery-operated applications

Supervisors Applications

• Portable electronic devices requiring efficient power management
• Microcontroller systems needing dependable power-on reset signals
• Embedded circuits operating within standard low-voltage ranges

Supervisors Procurement Notes

Verify the specific suffix DBZT corresponds to the tape-and-reel packaging configuration required for your assembly process. Confirm that the 4.55 V threshold aligns with your target rail voltage. Ensure compatibility with SOT-23-3 footprint dimensions during PCB layout review. Cross-reference the manufacturer datasheet for latest environmental compliance and marking specifications before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a fixed 4.55 V supervision point is necessary for single-rail monitoring. The 20 uA quiescent current makes it suitable for energy-constrained designs compared to higher-current alternatives. Consider the 200 ms delay duration to ensure adequate stabilization time for downstream logic. Verify that the absence of manual reset functionality meets the system's operational requirements without external intervention.

Supervisors Part Context

This part belongs to the TLV809 series of simple reset supervisors from Texas Instruments. The family offers various fixed threshold voltages to accommodate different supply rails while maintaining consistent package and performance characteristics. The TLV809I50 variant specifically targets applications requiring supervision near the 5 V nominal level, providing a standardized solution for power integrity monitoring in compact form factors.

Supervisors Replacement Considerations

The TPS3809I50DBVR serves as a functional substitute within the same monitoring category. Both devices share identical threshold voltages, output types, and package styles. Verify pinout compatibility and confirm that any differences in quiescent current or delay times do not impact the specific application timing requirements.
