XC6124A742MR-G

Supervisors Overview

The XC6124A742MR-G is a watchdog timer IC manufactured by Torex Semiconductor Ltd. It operates within an input voltage range of 0.8V to 6.0V and features a fixed threshold voltage of 4.2V. The device provides an open-drain or open-collector output signal. It is housed in a compact SOT-25-5 package, suitable for space-constrained designs. The component supports an operating temperature range from -40°C to +85°C, ensuring reliability in various industrial and commercial environments.

Supervisors Feature Summary

• Integrated watchdog timer functionality with automatic reset generation
• Fixed threshold voltage setting for precise monitoring
• Open-drain/open-collector output configuration for flexible interfacing

Supervisors Applications

• Microprocessor system supervision
• Industrial control unit monitoring
• Consumer electronics power management

Supervisors Procurement Notes

Verify the specific suffix 'MR-G' corresponds to the tape and reel packaging format and RoHS compliance status as documented in the official datasheet. Confirm the 4.2V threshold voltage matches the application requirements. Ensure the SOT-25-5 package dimensions align with the PCB footprint design. Cross-reference the manufacturer's latest documentation for any updates on lead-free specifications.

Supervisors Selection Notes

Select this component when a fixed 4.2V threshold is required for system supervision. The SOT-25-5 package offers a small form factor compared to larger alternatives. Consider the open-drain output capability if level shifting or wired-OR logic is needed. Verify that the operating temperature range meets the environmental conditions of the target application.

Supervisors Part Context

This part belongs to the XC6124 series of watchdog timers from Torex Semiconductor. The series includes variants with different threshold voltages and package options. The XC6124 series is designed for reliable system monitoring in portable and industrial devices. Other members of the family may offer adjustable thresholds or different output configurations.

Supervisors Replacement Considerations

Check for XC6124A740MR-G or XC6124A747ER-G if different threshold voltages are acceptable. Verify pin compatibility and package type before substitution. Ensure the replacement part meets the same electrical and thermal specifications.
