XC6123C240MG-G

Supervisors Overview

The XC6123C240MG-G is a high-precision voltage detector with watchdog functionality and ON/OFF control, manufactured by Torex Semiconductor using CMOS technology. It integrates a reference voltage source, delay circuit, comparator, and output driver. The detect voltage is internally fixed at 2.40V via laser trimming. The device supports six watchdog timeout periods ranging from 50ms to 1.6s and five release delay time settings from 3.13ms to 400ms. It operates within a voltage range of 1.6V to 5.0V with a typical temperature coefficient of +100ppm/°C.

Supervisors Feature Summary

• Integrates watchdog function with selectable timeout periods for system monitoring
• Features internal laser-trimmed detect voltage for high precision without external components
• Includes EN/ENB pin for independent control of watchdog operation while maintaining voltage detection
• Utilizes N-channel open-drain output configuration

Supervisors Applications

• Microprocessor watchdog monitoring and reset circuits
• Memory battery backup circuits
• System power-on reset circuits
• Power failure detection

Supervisors Procurement Notes

Verify the specific suffix MG-G against official Torex documentation to confirm package type and tape/reel specifications. Ensure the detect voltage code matches the required 2.40V threshold. Cross-reference the datasheet revision date to confirm technical parameters such as hysteresis width and operating voltage ranges remain consistent with current production standards.

Supervisors Selection Notes

Select this component when a precise voltage threshold of 2.40V is required alongside integrated watchdog timing capabilities. The XC6123 series is suitable for applications needing independent control over watchdog activation via the EN/ENB pin. Consider the available release delay options and watchdog timeout periods to match system recovery requirements. Verify that the N-channel open-drain output aligns with the target logic interface levels.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors. The XC6123 variant specifically includes an EN/ENB control pin for managing the watchdog function state independently of the voltage detection status. The series utilizes CMOS process technology to achieve low current consumption and high precision through internal laser trimming of the reference voltage.

Supervisors Replacement Considerations

Check for XC6123 series variants with different detect voltages or package suffixes. Verify compatibility with XC6121 or XC6122 models if the EN/ENB pin functionality differs in internal pull-up/pull-down configurations.
