XC6124E620MR-G

Supervisors Overview

The XC6124E620MR-G is a high-precision voltage monitor from Torex Semiconductor, housed in a compact SOT-25-5 surface-mount package. It features a fixed detection threshold of 2.0 V and operates within a supply voltage range of 1.0 V to 6.0 V. The device incorporates a built-in watchdog timer with a standard timeout period of 1.6 seconds and provides an open-drain output for system reset signaling. Designed for low-power applications, it draws only 12 µA of operating current while maintaining performance across an industrial temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer function controllable 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 thresholds without requiring external components.
• Features an internally pulled-up EN/ENB pin on the XC6124 series, enabling simplified circuit design when the watchdog function is utilized.

Supervisors Applications

• Microprocessor watchdog monitoring and reset circuits
• Memory battery backup circuits
• System power-on reset circuits

Supervisors Procurement Notes

Verify the specific suffix 'E620' confirms the 2.0 V detection threshold, as this variant defines the functional parameter. Confirm the 'MR-G' suffix indicates the SOT-25-5 package and RoHS compliance status required for your assembly process. Cross-reference the manufacturer's latest datasheet to ensure no obsolete lifecycle changes affect long-term availability or pinout compatibility.

Supervisors Selection Notes

Select this component when a fixed 2.0 V threshold is required for single-channel supervision. The integrated watchdog functionality distinguishes it from basic voltage detectors, making it suitable for systems needing fault monitoring alongside power supervision. Ensure the application does not require manual reset capabilities, as this model lacks that feature.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of CMOS voltage detectors. The XC6124 designation specifically denotes devices equipped with a watchdog timer input. These ICs are designed to eliminate external components by integrating delay circuits and precision comparators into a small footprint.
