XC6120N222NR-G

Supervisors Overview

The XC6120N222NR-G is a high-precision voltage detector manufactured by Torex Semiconductor using CMOS process technology. It incorporates a watchdog function and an ON/OFF control pin, eliminating the need for external components to generate release delay signals. The detect voltage is internally fixed at 2.2V via laser trimming. The device features a watchdog timeout period selectable from five settings ranging from 50ms to 1.6s and offers five release delay time options between 3.13ms and 400ms. The output configuration is V_DFL low upon detection. The EN/ENB pin allows independent control of the watchdog function while maintaining voltage detection operation.

Supervisors Feature Summary

• Integrated watchdog timer with selectable timeout periods
• Built-in delay circuit for signal release without external components
• Independent ON/OFF control for watchdog function via EN/ENB pin
• High-precision voltage detection using 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 NR-G against the official Torex datasheet to confirm package type and tape/reel specifications. Ensure the detect voltage code matches the required 2.2V threshold. Confirm RoHS compliance status if mandated by project requirements. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before procurement.

Supervisors Selection Notes

Select this component when a precise 2.2V detection threshold is required alongside integrated watchdog functionality. The internal pull-up or pull-down on the EN/ENB pin simplifies design by allowing the pin to remain open in certain configurations. Consider the available release delay and watchdog timeout ranges to ensure they align with system timing constraints. Verify that the operating voltage range encompasses the minimum input voltage expected in the application.

Supervisors Part Context

This part belongs to the XC6120 series of voltage detectors with watchdog functions. The series utilizes CMOS technology for low current consumption and high precision. The XC6120 variant specifically provides a negative logic output (V_DFL low) and includes an enable pin for controlling the watchdog feature independently of the voltage detection function.

Supervisors Replacement Considerations

The XC6121, XC6123, and XC6124 are related series members offering similar watchdog and detection features. Substitution requires verifying that the detect voltage, output polarity, and package dimensions are compatible. Check if the alternative part supports the same EN/ENB pin functionality and timing parameters.
