XC6122C225MG-G

Supervisors Overview

The XC6122C225MG-G is a single-channel voltage monitor and watchdog timer manufactured by Torex Semiconductor Ltd. It operates within a supply voltage range of 1 V to 6 V, featuring a fixed threshold voltage of 2.5 V. The device provides an open-drain output with a standard reset delay time of 50 ms. Designed for surface-mount installation in SOT-25-5 packages, it supports a wide operating temperature range from -40°C to +85°C. Key electrical characteristics include a maximum power dissipation of 250 mW and a typical static current consumption of 5 uA.

Supervisors Feature Summary

• Integrates voltage monitoring and watchdog timer functions in a single channel
• Provides open-drain output compatible with CMOS logic levels
• Supports battery backup switching for continuous operation during power transitions

Supervisors Applications

• Embedded system power supervision
• Microcontroller reset circuitry
• Battery-powered device monitoring

Supervisors Procurement Notes

Verify the specific suffix MG-G confirms the SOT-25-5 package and lead-free compliance. Confirm the C series designation aligns with the required 2.5 V threshold voltage for your design. Ensure the open-drain output configuration matches your system's pull-up requirements. Cross-reference the RoHS status if environmental compliance is mandatory for your region.

Supervisors Selection Notes

Select this component when a combined voltage supervisor and watchdog timer is required in a compact footprint. The 2.5 V threshold suits applications monitoring 3.3 V or similar logic rails. The low static current makes it suitable for battery-operated devices where power efficiency is critical. Verify that the 50 ms reset delay meets the startup timing requirements of the controlled microcontroller.

Supervisors Part Context

This part belongs to the XC6122 series of supervisory circuits from Torex Semiconductor. The series offers various threshold voltages and package options to accommodate different system requirements. The XC6122 family is designed for reliable power management in portable and industrial electronics, providing essential protection against brown-out conditions and software faults via the integrated watchdog function.

Supervisors Replacement Considerations

XC6121C225MG-G: Different output polarity (active high vs active low). XC6122A225MG-G: Different output type (push-pull vs open drain). XC6124C225MG-G: Different feature set (no watchdog timer). Verify pin compatibility and electrical specifications before substitution.
