XC6129C15A7R-G

Supervisors Overview

The XC6129C15A7R-G is a voltage detector manufactured by Torex Semiconductor, designed for monitoring single-channel power supply voltages. It operates within a supply voltage range of 1.3 V to 6 V and features a fixed threshold voltage of 1.5 V with an accuracy of 0.8%. The device utilizes a USPN-4 package and provides an active low, open-drain output. Key electrical parameters include a reset delay time of 50 µs, a maximum power dissipation of 100 mW, and a quiescent current of 420 nA. It supports manual reset functionality and includes a battery backup switch, operating reliably across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides precise voltage supervision with high detection accuracy for reliable system monitoring
• Features adjustable delay time to prevent false triggering during power-up or noise events
• Supports manual reset input for controlled system recovery independent of voltage thresholds
• Integrates a battery backup switch to maintain monitoring continuity during power transitions

Supervisors Applications

• Monitoring battery-powered portable electronic devices
• Supervising microcontroller and logic circuit power rails
• Ensuring stable operation in embedded systems requiring precise voltage thresholds
• Protecting data integrity in memory and storage subsystems

Supervisors Procurement Notes

Verify the specific suffix 'A7' corresponds to the required threshold voltage and package variant when sourcing. Confirm that the USPN-4 footprint matches your PCB layout constraints. Ensure compatibility with the active low open-drain output configuration in your design. Check RoHS compliance documentation for regulatory requirements. Validate the 50 µs delay time against your system's startup timing specifications.

Supervisors Selection Notes

Select this component when a fixed 1.5 V threshold is required for single-rail monitoring. Consider the low quiescent current for battery-sensitive applications. The open-drain output requires an external pull-up resistor; ensure this is accounted for in the design. Verify that the manual reset feature aligns with your system's reset strategy. Compare the USPN-4 package size against available board space.
