XC6124C449MR-G

Supervisors Overview

The XC6124C449MR-G is a voltage detector manufactured by Torex Semiconductor Ltd, featuring an ultra-low current consumption design optimized for battery-powered applications. It provides a precise output signal when the monitored supply voltage drops below or rises above a specific threshold, determined by the internal resistive divider network calibrated to 4.4V. The device incorporates hysteresis to prevent output oscillation during voltage transitions near the detection limit, ensuring stable logic levels. Packaged in a compact SOT-25-3 configuration, it supports operation across a wide temperature range and includes built-in delay circuits to filter transient noise spikes.

Supervisors Feature Summary

• Ultra-low current consumption architecture designed to minimize power drain in standby modes
• Integrated hysteresis function prevents output chattering during voltage threshold crossings
• Built-in delay circuit filters out short-duration noise pulses from the input signal

Supervisors Applications

• Battery-operated portable electronic devices requiring extended runtime
• Microprocessor reset circuits in embedded systems
• Voltage monitoring for memory backup supplies

Supervisors Procurement Notes

Verify the exact suffix 'MR-G' matches the required package type and tape/reel specifications before ordering. Confirm that the 4.4V detection voltage aligns with system requirements. Ensure compatibility with the target operating temperature range specified in the official datasheet. Cross-reference the manufacturing date code if long-term availability is critical for production runs.

Supervisors Selection Notes

Select this component when low quiescent current is prioritized over fast response times. The fixed 4.4V threshold suits applications where the nominal supply voltage operates slightly above this level. Consider the SOT-25-3 footprint constraints against available PCB space. Evaluate whether the inherent hysteresis width meets the noise immunity requirements of the specific circuit environment.

Supervisors Part Context

This part belongs to the XC6124 series of voltage detectors, which are widely used for supervisory functions in consumer electronics. The series offers various detection voltages and package options to accommodate different design needs. The XC6124C449MR-G specifically targets cost-sensitive applications requiring reliable voltage supervision without significant power overhead.

Supervisors Replacement Considerations

Direct substitutes include other parts from the XC6124 family with matching detection voltages and package styles. Verify pinout compatibility and electrical characteristics such as leakage current and response time before swapping components.
