XC6124A422MR-G

Supervisors Overview

The XC6124A422MR-G is a high-precision, low current consumption voltage detector with watchdog functions from Torex Semiconductor. It incorporates CMOS process technology and consists of a reference voltage source, delay circuit, comparator, and output driver. The detect voltage is internally fixed at 4.2V using laser trimming technology. The IC features an ON/OFF control pin to manage the watchdog function independently of the voltage detector operation. It provides six watchdog timeout period settings ranging from 50ms to 1.6s and five release delay time settings from 3.13ms to 400ms. The operating voltage range spans from 1V to 6V.

Supervisors Feature Summary

• Integrates a watchdog timer with selectable timeout periods for system monitoring
• Includes an ON/OFF control pin to enable or disable the watchdog function while maintaining voltage detection
• Utilizes laser trimming technology for fixed internal detect voltage settings
• Features built-in delay circuits to eliminate the need for external components

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 codes against official Torex documentation to confirm exact threshold voltages and package variations. Ensure compatibility with required watchdog timeout and release delay settings before procurement. Confirm RoHS compliance status and moisture sensitivity levels for storage and handling requirements.

Supervisors Selection Notes

Select this component when a dedicated voltage monitor with integrated watchdog functionality is required. The fixed 4.2V threshold suits applications monitoring standard logic supply rails. Consider the available release delay options to match system startup timing requirements. Verify that the 1V to 6V operating range aligns with the target power supply specifications.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors. The series offers various detect voltage ranges and watchdog configurations. The XC6124 variant specifically includes the watchdog timer feature. Different suffixes indicate variations in detect voltage and package type within the same functional family.

Supervisors FAQ

How is the watchdog function controlled?

The watchdog function can be turned ON or OFF via the EN/ENB pin. Setting this pin to a specific level disables the watchdog while the voltage detector continues to operate.

What is the detect voltage accuracy method?

The detect voltages are internally fixed using laser trimming technology, ensuring high precision without requiring external calibration components.
