XC6122D330MR-G

Supervisors Overview

The XC6122D330MR-G is a high-precision voltage detector with watchdog functionality, manufactured by Torex Semiconductor using CMOS technology. It features an internal reference voltage source, delay circuit, comparator, and output driver. The detect voltage (VDF) ranges from 1.6V to 5.0V in 100mV increments via laser trimming. The device includes a watchdog timeout period selectable between 50ms and 1.6s, and a release delay time adjustable from 3.13ms to 400ms. The output configuration is N-channel open drain, providing a low signal upon detection. The operating voltage range supports various system requirements.

Supervisors Feature Summary

• Integrated watchdog function with selectable timeout periods for system monitoring
• Internal laser-trimmed detect voltage settings eliminate external component needs
• Built-in delay circuit provides release delay without additional parts
• EN/ENB pin allows independent control of watchdog function while maintaining voltage detection

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 complete part number including the -G suffix against official Torex documentation to confirm specific packaging or environmental compliance details. Ensure the detect voltage code D330 corresponds to the required threshold. Cross-reference the datasheet revision date to confirm current specifications. Confirm availability through authorized distributors only.

Supervisors Selection Notes

Select this component when precise voltage monitoring with integrated watchdog protection is required. The fixed detect voltage eliminates calibration needs. Consider the available watchdog timeout and release delay options to match system timing requirements. Verify that the N-channel open drain output aligns with the target logic interface. Check temperature characteristics if operating in extreme environments.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of high-precision, low-current voltage detectors. The XC6122 variant specifically incorporates the EN/ENB pin for watchdog control enable/disable functionality. The series utilizes CMOS process technology for low power consumption. The D330 suffix indicates a specific detect voltage setting within the 1.6V to 5.0V range.

Supervisors Replacement Considerations

Check for direct substitutes within the XC6121-XC6124 family with compatible detect voltages and package types. Verify equivalent watchdog timeout and delay settings. Ensure pin compatibility and electrical characteristics match before substitution.

Supervisors FAQ

How is the watchdog function controlled?

The watchdog function can be turned ON or OFF by setting the EN/ENB pin to a high or low level, respectively, while the voltage detector remains operational.

What determines the detect voltage accuracy?

The detect voltage is internally fixed using laser trimming technology, ensuring high precision across the specified range.

Can the EN/ENB pin be left open?

Yes, for the XC6122 series, the EN/ENB pin is internally pulled up to the VIN pin or pulled down to the VSS pin, allowing it to be left open when using the watchdog function.
