XC6122C242ER-G

Supervisors Overview

The XC6122C242ER-G is a high-precision voltage monitor manufactured by Torex Semiconductor, designed for supervisory circuit applications. It operates within a supply voltage range of 1 V to 6 V and features a fixed detection threshold of 2.4 V. The device incorporates a watchdog timer with a standard timeout period of 50 ms and provides a release delay time of 50 ms. It utilizes an N-channel open-drain output configuration and consumes a typical operating current of 12 µA with a static current of 5 µA. The component is housed in a USP-6C package and supports an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog function with selectable timeout periods and a built-in delay circuit that eliminates the need for external components.
• Features an EN/ENB pin that allows independent control over the watchdog function while maintaining voltage detection operation.
• Employs laser trimming technology to ensure high-precision detection voltages with a temperature characteristic of +100 ppm/°C.

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 the manufacturer's datasheet to confirm the package type and tape/reel specifications. Ensure the required detection voltage of 2.4 V aligns with the system design requirements. Confirm RoHS compliance status through official documentation before integration into production environments.

Supervisors Selection Notes

Select this component when a fixed 2.4 V threshold is required for single-input voltage monitoring. Consider the USP-6C package size for space-constrained designs. Verify that the 50 ms reset delay and watchdog timeout meet the timing constraints of the target microprocessor or memory system.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of CMOS voltage detectors. The series is characterized by low current consumption and high precision. The XC6122 variant specifically includes a watchdog function controlled via the EN/ENB pin, distinguishing it from basic voltage monitors without watchdog capabilities.

Supervisors Replacement Considerations

Cross-reference with other XC6122 series variants having different detection voltages if the threshold does not match. Check XC6123 or XC6124 series parts for similar functionality with alternative packages or slightly different electrical characteristics.
