TLV803EA43DCKR

Supervisors Overview

The TLV803EA43DCKR is a low-power voltage supervisor from the Texas Instruments TLV803E series, designed to monitor a single power supply rail. It features an active-low, open-drain reset output with a fixed threshold voltage of 4.3 V and a reset delay time of 200 ms. The device operates within a supply voltage range of 1.7 V to 6 V and maintains high accuracy of 0.5%. It is housed in a compact SC-70-3 surface-mount package and supports operation across an extended temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Provides reliable system reset generation through precise voltage monitoring with 0.5% accuracy
• Features ultra-low quiescent current consumption for battery-powered applications
• Delivers active-low open-drain reset signal with a standard 200 ms delay timer

Supervisors Applications

• Portable electronic devices requiring efficient power management
• Embedded systems needing microprocessor reset supervision
• Battery-operated equipment with strict power constraints

Supervisors Procurement Notes

Verify the specific suffix DCKR confirms the SC-70-3 package and reel packaging configuration. Ensure the EA grade matches the required 0.5% accuracy specification for your design. Confirm the 4.3 V threshold aligns with the monitored rail voltage. Check RoHS compliance status as indicated in official documentation before finalizing procurement.

Supervisors Selection Notes

Select this component when a single-supervisor solution with high precision is required. The SC-70-3 package offers space efficiency for dense PCB layouts. The wide operating temperature range suits industrial or automotive environments. Consider the open-drain output compatibility with the target logic levels during interface design.

Supervisors Part Context

This part belongs to the TLV803E family of voltage supervisors, which emphasizes low power consumption and high accuracy. The TLV803 series provides various threshold options and package types to suit different monitoring needs. The EA variant specifically denotes the accuracy grade and package style within the broader product line.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the TLV803 series that offer similar threshold voltages. Verify that any substitute maintains the same SC-70-3 footprint and electrical characteristics. Ensure the replacement supports the required operating temperature range and accuracy specifications.
