XC6129C55D7R-G

Supervisors Overview

The XC6129C55D7R-G is a single-channel voltage detector manufactured by Torex Semiconductor Ltd. It operates within a supply voltage range of 1.3 V to 6 V and features a detection threshold of 5.5 V. The device utilizes a push-pull/totem pole output configuration with active-low reset signaling. It incorporates a standard reset delay time of 50 µs to prevent false triggering during power transitions. The component is housed in a compact 4-USPN (0.90x1.2) surface-mount package and supports manual reset functionality. It is designed for operation across an extended temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Provides precise voltage monitoring with a fixed 5.5 V detection threshold for system supervision.
• Features a push-pull output stage capable of sourcing and sinking current for robust drive capability.
• Includes a built-in reset delay timer to ensure stable operation during power-up and power-down sequences.
• Supports manual reset input for initiating system restarts independently of voltage conditions.

Supervisors Applications

• Monitoring battery-powered systems where low standby current and precise threshold are required.
• Supervising microprocessor or microcontroller power rails to ensure reliable startup and shutdown.
• Industrial control circuits requiring wide operating temperature stability and manual reset capabilities.

Supervisors Procurement Notes

Verify the specific suffix 'D' indicates the correct output type and threshold variant against the official datasheet, as suffixes define electrical characteristics. Confirm the 4-USPN package dimensions match your PCB footprint requirements. Ensure compliance with RoHS and REACH regulations if applicable to your region. Cross-reference the manufacturer part number directly with Torex Semiconductor documentation to avoid counterfeit components.

Supervisors Selection Notes

Select this component when a fixed 5.5 V threshold is required for supervising higher voltage rails within the 6 V maximum limit. The push-pull output is suitable for driving loads directly without external pull-up resistors, simplifying circuit design. Consider the 50 µs delay time for applications tolerant of minor power-supply transients. Evaluate the 4-USPN package size against available board space constraints.
