XC6121E618ER-G

Supervisors Overview

The XC6121E618ER-G is a high-precision voltage detector with watchdog function and ON/OFF control, manufactured by Torex Semiconductor Ltd. 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 1.8V using laser trimming technology. The operating voltage range is 1.6V to 5.0V. The package is USP-6 (6-UFDFN Exposed Pad).

Supervisors Feature Summary

• Integrated watchdog timer function for system monitoring.
• Built-in release delay circuit eliminates external components.
• EN/ENB pin allows forced OFF of the watchdog function while maintaining voltage detection.

Supervisors Applications

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

Supervisors Procurement Notes

Verify the specific suffix 'E6' corresponds to the 1.8V threshold and standard timeout settings as defined in the official XC6121 series datasheet. Confirm the package marking and RoHS compliance status match the manufacturer's current production specifications before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a fixed 1.8V detection threshold is required within the 1.6V to 5.0V operating range. Ensure the application utilizes the EN/ENB pin logic correctly to manage the watchdog state, as the XC6121 series requires specific pin configurations to disable the watchdog function if needed.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors. These ICs are designed for high-precision applications requiring low current consumption. The XC6121 variant specifically features an open-drain output configuration suitable for interfacing with various digital logic families.

Supervisors Replacement Considerations

Direct substitutes include other XC6121 series variants with different threshold voltages or timeout periods, such as XC6121E518ER-G or XC6121E718ER-G, provided the electrical parameters align with the design requirements.
