XC6123E631ER-G

Supervisors Overview

The XC6123E631ER-G is a high-precision voltage detector with watchdog function and ON/OFF control from Torex Semiconductor. It incorporates CMOS process technology, featuring a detect voltage range of 1.6V to 5.0V in 100mV increments via laser trimming. The device operates within a supply voltage range of 1.0V to 6.0V with a typical operating current of 12μA. It includes an N-channel open-drain output, configurable release delay times ranging from 3.13ms to 400ms, and six watchdog timeout settings from 50ms to 1.6s. The EN/ENB pin allows independent control of the watchdog function while maintaining voltage detection.

Supervisors Feature Summary

• Integrated watchdog timer with selectable timeout periods for system reliability monitoring
• ON/OFF control capability via EN/ENB pin to disable watchdog without affecting voltage detection
• Built-in delay circuit eliminates need for external components for release delay timing
• High-precision detection voltage set by laser trimming technology

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 part number matches the required detect voltage code (631) and series variant (E). Cross-reference with the latest datasheet revision to confirm RoHS compliance and environmental certifications before procurement.

Supervisors Selection Notes

Select this component when precise voltage monitoring with integrated watchdog functionality is required. The EN/ENB pin offers flexibility to manage watchdog states independently. Verify that the required detect voltage falls within the 1.6V to 5.0V range and that the available delay and timeout settings meet the system timing requirements.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors. These ICs are designed for low current consumption applications using CMOS technology. The series provides various detect voltages and packaging options to suit different embedded system needs, focusing on reliability through built-in watchdog and delay features.

Supervisors Replacement Considerations

Check for other XC6123 variants with compatible detect voltages and packages. Verify if XC6121 or XC6122 series parts offer equivalent functionality with different pin configurations or electrical characteristics suitable for the design.
