XC6122D630MR-G

Supervisors Overview

The XC6122D630MR-G is a high-precision voltage detector with a watchdog function manufactured by Torex Semiconductor. It operates within a supply voltage range of 1V to 6V and features a fixed detect voltage of 3.0V. The device incorporates an N-channel open-drain output and includes a built-in delay circuit for release timing. It supports watchdog timeout periods ranging from 50ms to 1.6s and offers five selectable release delay time settings between 3.13ms and 400ms. The IC consumes low current, typically 12µA, and maintains detect voltage temperature characteristics of +100ppm/°C.

Supervisors Feature Summary

• Integrates a watchdog timer function controllable via the EN/ENB pin while maintaining voltage detection operation
• Utilizes laser trimming technology to ensure high-precision internal fixed detect voltages
• Includes a built-in delay circuit that eliminates the need for external components for release delay signals
• Features an N-channel open-drain output configuration for direct interfacing with logic circuits

Supervisors Applications

• Microprocessor watchdog monitoring and reset circuits
• Memory battery backup circuits
• System power-on reset circuits
• Power failure detection systems

Supervisors Procurement Notes

Verify the specific suffix 'MR-G' against the official Torex datasheet to confirm package type and tape/reel specifications. Ensure the detect voltage code corresponds to the required 3.0V threshold. Confirm RoHS compliance status through the manufacturer's latest documentation before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a fixed 3.0V threshold is required for system supervision. The integrated watchdog function simplifies design by removing external timing components. Consider the 1V minimum operating voltage for compatibility with low-voltage logic families. Verify that the N-channel open-drain output aligns with the pull-up requirements of the target microprocessor interface.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of CMOS voltage detectors. These devices are designed for applications requiring precise voltage monitoring combined with system integrity checks. The series utilizes advanced CMOS process technology to achieve low current consumption and high accuracy across industrial temperature ranges.

Supervisors Replacement Considerations

Cross-reference with other XC6122 variants having different detect voltage codes if the threshold requirement changes. Verify pinout compatibility with SOT-25 packages before substituting with similar supervisory ICs from other manufacturers.
