XC6124A631MR-G

Supervisors Overview

The XC6124A631MR-G is a voltage detector with watchdog function and ON/OFF control from Torex Semiconductor. It features an internally fixed detect voltage of 3.1V with a typical hysteresis width of VDFL x 5%. The device offers six selectable watchdog timeout periods ranging from 50ms to 1.6s and five release delay time settings from 3.13ms to 400ms. Supply current is typically 14.0μA at Ta=85℃ with VIN=2.7V. It utilizes laser trimming technology for precision and includes an EN/ENB pin for controlling the watchdog function.

Supervisors Feature Summary

• Integrated watchdog timer with selectable timeout periods for system reliability
• ON/OFF control capability via EN/ENB pin for power management optimization
• Precision voltage detection using laser trimming technology for accurate thresholds
• Configurable release delay times to prevent false triggering during transient events

Supervisors Applications

• Microprocessor reset circuits
• Battery-powered equipment monitoring
• Embedded system supervision

Supervisors Procurement Notes

Verify the specific suffix MR-G indicates the SOT-25-5 package configuration. Confirm RoHS compliance status through official documentation. Ensure the detect voltage code A631 corresponds to the required 3.1V threshold for your application design. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Supervisors Selection Notes

Select this component when a precise 3.1V detection threshold is required alongside watchdog functionality. Consider the supply current specifications against battery life requirements. Evaluate the available watchdog timeout options to match the microprocessor's expected response time. Verify that the SOT-25-5 package fits the PCB layout constraints.

Supervisors Part Context

This part belongs to the XC6124 series of voltage detectors with watchdog functions. The series provides various detect voltages and package options. The XC6124 variant specifically integrates watchdog timer capabilities, distinguishing it from basic voltage detectors like the XC6121 or XC6122 series which may lack these advanced supervision features.

Supervisors Replacement Considerations

XC6124E631MR-G is a confirmed substitute within the same series offering similar functionality.
