XC6122C727MR-G

Supervisors Overview

The XC6122C727MR-G is a high-precision voltage monitor manufactured by Torex Semiconductor, designed for system supervision and microprocessor reset management. It operates within a supply voltage range of 1.0 V to 6.0 V and features a fixed detection threshold of 2.7 V with ±2% accuracy. The device utilizes CMOS technology, drawing a typical operating current of 12 µA and a static current of 5 µA. It incorporates an integrated watchdog timer and provides an active-low open-drain output. The component is housed in a compact SOT-25-5 surface-mount package and supports operation across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer function controllable via the EN/ENB pin to manage system stability independently of the voltage monitoring circuit.

Supervisors Applications

• Microprocessor reset circuits
• Memory battery backup systems
• Power failure detection

Supervisors Procurement Notes

Verify the specific release delay time configuration required for your application, as this parameter varies across the XC6122 series. Confirm that the SOT-25-5 package dimensions align with your PCB footprint constraints. Ensure the open-drain output interface is compatible with the pull-up resistor requirements of your target logic level.

Supervisors Selection Notes

Select this part when a 2.7 V threshold is required for precise power rail supervision. Consider the low quiescent current for battery-operated designs. Verify if the built-in watchdog timeout meets timing requirements or if external timing components are needed, noting that internal delays are fixed per variant.

Supervisors Part Context

This component belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors with watchdog functions. These devices share common architectural features, including CMOS construction and laser-trimmed threshold voltages. The XC6122 variant specifically denotes the package type and feature set within the broader family of supervisory ICs offered by Torex Semiconductor.

Supervisors Replacement Considerations

Cross-reference with other XC6122 series variants such as XC6122C720MR-G or XC6122C730MR-G if different threshold voltages are acceptable. Ensure any substitute maintains the same SOT-25-5 package and electrical characteristics to guarantee pin compatibility.
