XC6129N21A7R-G

Supervisors Overview

The XC6129N21A7R-G is a voltage detector manufactured by Torex Semiconductor Ltd, designed for monitoring single-channel power supply voltages. It features an adjustable delay time and operates within a supply voltage range of 0.7 V to 6 V. The device provides a CMOS open-drain output with active-low reset functionality. Key electrical parameters include a threshold voltage of 2.1 V, with over-voltage and under-voltage thresholds specified at 2.1168 V and 2.0832 V respectively. The reset delay time is fixed at 30 µs, and the accuracy is rated at 0.8%. Quiescent current consumption is low, with typical operating current at 800 nA and static current at 600 nA. Power dissipation is limited to 100 mW.

Supervisors Feature Summary

• Features an adjustable delay time capability for customized reset timing control.
• Provides high-precision voltage monitoring with 0.8% accuracy for reliable system supervision.
• Includes battery backup switch functionality to maintain detection during power transitions.

Supervisors Applications

• Portable electronic devices requiring low quiescent current monitoring
• Battery-powered systems needing precise voltage threshold detection
• General-purpose supervisory circuits in consumer electronics

Supervisors Procurement Notes

Verify the specific suffix 'A7R' corresponds to the required threshold voltage and packaging configuration. Confirm RoHS compliance status through official documentation. Ensure the USPN-4B02-4 package footprint matches the design layout. Check for any lead-free or halogen-free certifications if required by project specifications.

Supervisors Selection Notes

Select this component when a 2.1 V threshold with 0.8% accuracy is required. Consider the 30 µs reset delay and open-drain output compatibility with the target logic levels. Evaluate the 600 nA static current against power budget constraints. Ensure the operating temperature range of -40°C to +85°C meets environmental requirements.

Supervisors Part Context

This part belongs to the XC6129 series of voltage detectors from Torex Semiconductor. The series offers various threshold voltages and package options. The XC6129N21A7R-G specifically utilizes the USPN-4B02-4 package and includes manual reset functionality support via external components, distinguishing it from non-reset variants.

Supervisors Replacement Considerations

XC6129N21C7R-G: Same threshold voltage but different delay time characteristics. XC6129N21J7R-G: Alternative variant within the same series with potentially different delay settings. Verify pinout and electrical parameters before substitution.
