XC6124E447MR-G

Supervisors Overview

The XC6124E447MR-G is a voltage monitor manufactured by Torex Semiconductor Ltd, designed for supervising single-channel power supply voltages. It operates within a supply voltage range of 1 V to 6 V and features an open-drain output type compatible with CMOS logic levels. The device incorporates a built-in watchdog timer and a backup battery switch function to ensure system reliability during power fluctuations. It is housed in a compact SOT-25-5 surface-mount package, suitable for space-constrained applications. The component supports a reset delay time of 50 ms and maintains a low operating current of 12 uA, ensuring efficient power management in portable and industrial electronics.

Supervisors Feature Summary

• Integrates a watchdog timer for automated system recovery
• Includes a backup battery switch function for seamless power transition
• Provides open-drain output for flexible logic interfacing
• Supports manual reset functionality via dedicated input pin

Supervisors Applications

• Portable electronic devices requiring low-power supervision
• Industrial control systems needing watchdog protection
• Battery-powered equipment with backup switching requirements
• Embedded systems monitoring single voltage rails

Supervisors Procurement Notes

Verify the exact threshold voltage and reset delay specifications against the official datasheet before procurement, as suffixes may indicate variations. Confirm availability through authorized distributors, noting that lead times can vary based on manufacturing schedules. Ensure the ordering quantity aligns with factory packaging requirements to avoid partial reel issues. Cross-reference the part number with the manufacturer's latest documentation to confirm RoHS compliance and environmental certifications.

Supervisors Selection Notes

Select this component when a single-channel voltage monitor with integrated watchdog and backup functions is required. The SOT-25-5 package offers a balance between size and thermal performance for surface-mount assembly. Consider the 12 uA operating current for battery-sensitive designs. Ensure the monitored voltage range falls within the 1 V to 6 V operational limits. Verify that the open-drain output configuration matches the downstream logic interface requirements.

Supervisors Part Context

This part belongs to the XC6124 series of voltage monitors from Torex Semiconductor, which are designed for high-reliability applications. The series typically includes variants with different threshold voltages and output configurations. The XC6124E447MR-G specifically denotes a version with a defined threshold and package style. It is categorized under PMIC - Power Management ICs, focusing on supervisory circuits rather than active power conversion.

Supervisors Replacement Considerations

Direct substitutes within the XC6124 series may exist with different threshold voltages or package options. Verify functional compatibility regarding watchdog timing and backup switch behavior when considering alternative part numbers. Generic voltage monitors without integrated watchdog or backup features are not direct replacements unless these functions are omitted in the design.
