XC6129C37A9R-G

Supervisors Overview

The XC6129C37A9R-G is a voltage detector manufactured by Torex Semiconductor Ltd, designed for monitoring single power supply lines. It features an adjustable delay time to prevent false triggering during power-up or brown-out conditions. The device operates within a wide input voltage range and provides a reliable reset signal output. Key electrical parameters include a threshold voltage of 3.7V, a maximum operating voltage of 6V, and a standard reset timeout of 50µs. It supports an active-low output configuration and functions across an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Adjustable delay time functionality to ensure stable operation during transient voltage events
• Dedicated sense pin allows for precise voltage monitoring independent of the power supply line
• CMOS output structure providing low current consumption and compatibility with digital logic

Supervisors Applications

• Portable electronic devices requiring battery voltage supervision
• Microprocessor system reset circuits
• Brown-out detection in embedded systems

Supervisors Procurement Notes

Verify the specific suffix codes against the official datasheet to confirm threshold voltage and package type accuracy. Ensure the ordering quantity aligns with manufacturer reel specifications. Confirm RoHS compliance status if required for your assembly process. Cross-reference the part number with authorized distributors to avoid counterfeit components.

Supervisors Selection Notes

Select this component when a fixed 3.7V threshold is required for single-supply monitoring. Consider the adjustable delay feature if noise immunity is critical. Compare power consumption metrics against other series if ultra-low standby current is a primary constraint. Verify that the USPQ-4B05 package fits the PCB layout constraints.

Supervisors Part Context

This part belongs to the XC6129 series of voltage detectors from Torex Semiconductor. The series is characterized by high precision and low power consumption. The XC6129C37A9R-G specifically denotes the 3.7V threshold variant within this family, utilizing the C-series designation for specific operational characteristics defined by the manufacturer.

Supervisors Replacement Considerations

Direct substitutes may include other XC6129 variants with different threshold voltages if the 3.7V requirement is flexible. Check for equivalent parts from other manufacturers offering similar USPQ-4B05 packages and CMOS outputs. Ensure functional compatibility regarding delay adjustability and output polarity before substitution.
