XC6122E625MR-G

Supervisors Overview

The XC6122E625MR-G is a high-precision voltage monitor manufactured by Torex Semiconductor, designed for single-input supervision within a 1 V to 6 V operating range. It features a fixed detection threshold of 2.5 V and utilizes an N-channel open-drain CMOS output that asserts low upon detection. The device incorporates a built-in delay circuit providing a reset delay time of 200 ms, eliminating the need for external timing components. Key electrical characteristics include a maximum supply current of 12 µA and a quiescent current of 5 µA. It operates reliably across a temperature range of -40°C to +85°C and is housed in a compact SOT-25-5 surface-mount package.

Supervisors Feature Summary

• Integrates a watchdog timer function with ON/OFF control capability via the EN/ENB pin, allowing the watchdog to be disabled while the voltage detector remains active.
• Utilizes laser trimming technology to ensure high-precision internal detection voltages without requiring external adjustment components.
• Features an internally pulled-up EN/ENB pin configuration that permits operation with the control pin left open when utilizing the watchdog function.

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 'MR' corresponds to the required tape-and-reel packaging format for automated assembly processes. Confirm that the 2.5 V threshold aligns precisely with the target system voltage requirements. Ensure the SOT-25-5 footprint matches the design layout. Validate RoHS compliance status through the official manufacturer datasheet prior to final procurement authorization.

Supervisors Selection Notes

Select this component when a fixed 2.5 V threshold is required for supervising single-rail systems. The integrated watchdog functionality makes it suitable for applications needing both voltage supervision and processor reset protection. Consider the low 5 µA static current for battery-operated designs. Verify that the 200 ms release delay meets the system's startup timing constraints before implementation.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors from Torex Semiconductor. These devices are characterized by CMOS process technology, offering high precision and low current consumption. The series provides various detection voltages and package options, with the XC6122 variant specifically featuring the watchdog input control feature described in the general documentation.

Supervisors Replacement Considerations

Other parts within the XC6122 series may serve as substitutes if different detection thresholds or delay times are acceptable. Verify pin compatibility and package dimensions (SOT-25-5) for direct replacement. Cross-reference specific suffix codes to ensure identical electrical parameters and packaging formats.
