XC6122F645ER-G

Supervisors Overview

The XC6122F645ER-G is a high-precision CMOS voltage detector with a watchdog function and ON/OFF control, manufactured by Torex Semiconductor Ltd. It incorporates a reference voltage source, delay circuit, comparator, and output driver. The detect voltage is internally fixed at 6.45V via laser trimming technology. The device features an N-channel open-drain output that goes low when the detected voltage falls below the threshold. It includes a built-in delay circuit for release delay time and supports watchdog timeout period settings. The EN/ENB pin allows independent control of the watchdog function while maintaining voltage detection operation.

Supervisors Feature Summary

• Integrates watchdog timer functionality with voltage detection capabilities
• Features internal laser-trimmed detect voltage for high precision
• Includes built-in delay circuit eliminating external component requirements
• Provides ON/OFF control for watchdog function via dedicated pin

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 ER-G against official Torex documentation to confirm package type and tape/reel specifications. Ensure the detect voltage code F645 corresponds to the required 6.45V threshold for your application. Cross-reference the datasheet revision date to confirm compatibility with current manufacturing standards and environmental compliance requirements.

Supervisors Selection Notes

Select this component when a fixed 6.45V detection threshold is required alongside integrated watchdog protection. The XC6122 series offers internal pull-up or pull-down options on the EN/ENB pin, simplifying interface design. Consider the available release delay and watchdog timeout ranges to match system timing constraints without requiring external RC networks.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors from Torex. These devices utilize CMOS process technology to achieve low current consumption. The series differentiates primarily by output configuration and watchdog integration levels, with the XC6122 specifically combining watchdog functions with ON/OFF control capabilities.

Supervisors Replacement Considerations

Compatible substitutes within the same family include XC6121, XC6123, and XC6124 variants with matching detect voltage codes. Verify that alternative parts support the required 6.45V threshold and compatible output configurations before substitution.
