XC6129C39F9R-G

Supervisors Overview

The XC6129C39F9R-G is a single-channel voltage detector manufactured by Torex Semiconductor Ltd. It operates within a supply voltage range of 0.7V to 5.5V and features an adjustable detection threshold, specifically set at 3.9V for this variant. The device provides a low-active reset output with an open-drain configuration. It includes an internally adjustable delay time function to prevent false triggering during power transitions. The component supports surface-mount installation in a compact 4-USPQ-B05 package and functions reliably across an industrial temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Adjustable detection threshold voltage allows precise monitoring of specific supply rails.
• Internally adjustable delay time function prevents erroneous reset signals during power-up or noise events.
• Low-active open-drain reset output simplifies interface with various logic families.

Supervisors Applications

• Portable electronic devices requiring reliable power management
• Battery-operated equipment needing low-voltage cutoff protection
• Embedded systems utilizing microcontrollers with strict reset timing requirements

Supervisors Procurement Notes

Verify the exact threshold voltage code suffix against the official datasheet before ordering, as minor alphanumeric changes indicate different trip points. Confirm package compatibility with PCB footprint designs. Ensure supply chain sources provide genuine components with valid traceability documentation to avoid counterfeit risks in critical applications.

Supervisors Selection Notes

Select this component when a fixed high-precision threshold is insufficient and manual adjustment capability is required. Compare the adjustable delay feature against fixed-delay alternatives if system noise immunity is a primary concern. Evaluate the open-drain output requirement against push-pull options available in other series variants to ensure logical compatibility with the target circuit design.

Supervisors Part Context

This part belongs to the XC6129 series of ultra-small voltage detectors from Torex Semiconductor. The series is characterized by its miniature packaging options and low current consumption, making it suitable for space-constrained portable electronics. The XC6129 family offers both fixed and adjustable threshold versions to accommodate diverse monitoring needs.

Supervisors Replacement Considerations

Equivalent parts include XC6129N39F9R-G and XC6129A39F9R-G, which share identical electrical specifications and pinouts but differ in package type. Verify that substitute packages fit the existing board layout constraints before implementation.
