TLV803EF26DBZR

Supervisors Overview

The TLV803EF26DBZR is a low-power voltage supervisor from Texas Instruments, designed to monitor a single input voltage. It features an active-low, open-drain reset output and operates within a supply voltage range of 1.7 V to 6 V. The device triggers a reset when the monitored voltage falls below a threshold of 2.64 V with 0.5% accuracy. It includes a fixed reset delay time of 400 ms and functions reliably across an industrial temperature range of -40°C to +125°C. Packaged in a compact SOT-23-3 case, it consumes only 400 nA of static current.

Supervisors Feature Summary

• Provides precise voltage monitoring with high accuracy for reliable system supervision
• Features ultra-low static current consumption to extend battery life in portable applications
• Delivers active-low open-drain reset signals compatible with various digital logic interfaces

Supervisors Applications

• Portable consumer electronics requiring extended battery operation
• Battery-powered embedded systems needing voltage supervision
• Industrial control units operating in extreme temperature environments

Supervisors Procurement Notes

Verify the specific suffix DBZR corresponds to the SOT-23-3 package and reel/cut-tape availability. Confirm the EF26 designation matches the required 2.64 V threshold and 400 ms delay for your design. Ensure RoHS compliance documentation is obtained. Cross-reference the manufacturer part number against official TI databases to avoid counterfeit components during sourcing.

Supervisors Selection Notes

Select this component when a fixed 2.64 V threshold is required with minimal quiescent current. The 400 ms delay suits applications tolerant of longer startup times. Compare against other TLV803 variants if different thresholds or faster reset delays are needed. Verify that the open-drain output configuration aligns with the pull-up requirements of the target microcontroller or logic circuit.

Supervisors Part Context

This part belongs to the TLV803E series of voltage supervisors, which offers various threshold voltages and packages. The TLV803 family is characterized by low power consumption and small footprint options like SOT-23 and SC-70. This specific model integrates a fixed threshold without manual reset or watchdog timer capabilities, focusing on simple power-on reset functionality.
