XC6124C631MR-G

Supervisors Overview

The XC6124C631MR-G is a high-precision voltage monitor with watchdog functionality manufactured by Torex Semiconductor. It operates within a supply voltage range of 1.0 V to 6.0 V and features a fixed detection threshold of 3.1 V. The device utilizes CMOS technology, drawing an operating current of 12 µA and a standby current of 5 µA. It provides an open-drain output and includes a built-in delay circuit for release timing. The component is housed in a compact SOT-25-5 package and supports operation across temperatures from -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer function with selectable timeout periods for system reliability monitoring.
• Features a built-in delay circuit that eliminates the need for external components to generate release delay signals.
• Includes an EN/ENB pin allowing independent control to disable the watchdog function while maintaining voltage detection.

Supervisors Applications

• Microprocessor reset circuits requiring precise power-on reset timing.
• Watchdog monitoring for embedded systems and digital controllers.
• Battery backup switching applications ensuring data integrity during power transitions.

Supervisors Procurement Notes

Verify the specific suffix configuration against the official datasheet to confirm the exact threshold voltage and delay settings. Ensure the ordering part number matches the required package variant and temperature grade. Cross-reference the manufacturer's latest documentation for any updates on RoHS compliance or pinout definitions prior to procurement.

Supervisors Selection Notes

Select this component when a low-power supervisor with integrated watchdog capabilities is required. The fixed 3.1 V threshold suits applications monitoring standard logic rails. Consider the SOT-25-5 footprint for space-constrained designs. Verify that the open-drain output compatibility aligns with the downstream logic interface requirements.

Supervisors Part Context

This part belongs to the XC6124 series, which groups high-precision voltage detectors with watchdog functions. The series shares common architectural features including CMOS process technology and laser-trimmed accuracy. Variants within the series differ primarily in detection thresholds and delay times, offering flexibility for diverse power management needs.

Supervisors Replacement Considerations

Direct substitutes include other XC6124 variants with matching 3.1 V thresholds and compatible packages. Verify functional equivalence regarding watchdog timeout values and release delay characteristics before substitution.
