XC6124D722MR-G

Supervisors Overview

The XC6124D722MR-G is a single-channel voltage monitor and supervisor circuit manufactured by Torex Semiconductor. It operates within a supply voltage range of 1 V to 6 V, featuring a fixed detection threshold of 2.2 V. The device incorporates an integrated watchdog timer with a standard reset delay time of 50 ms. It utilizes an open-drain CMOS output for system reset signaling. Key electrical characteristics include a maximum power dissipation of 250 mW, a typical operating supply current of 12 uA, and a low static current of 5 uA. The component supports battery backup switching functionality and is designed for surface-mount installation in the SOT-25-5 package.

Supervisors Feature Summary

• Integrates a watchdog timer function for automated system recovery from software faults
• Provides dedicated battery backup switching capability to maintain data integrity during power transitions
• Features power failure detection logic to monitor input voltage stability continuously

Supervisors Applications

• Portable electronic devices requiring low standby current consumption
• Battery-powered systems utilizing backup switching mechanisms
• Embedded controllers needing watchdog timer protection against software hangs

Supervisors Procurement Notes

Verify the specific suffix codes against official Torex documentation to confirm exact threshold voltages and functional variants. Ensure compatibility with the target PCB footprint, specifically the SOT-25-5 package dimensions. Confirm RoHS compliance status through the manufacturer's latest environmental declarations before finalizing procurement specifications.

Supervisors Selection Notes

Select this component when a fixed 2.2 V monitoring threshold is required for single-supply applications. Consider the 50 ms reset delay and watchdog integration if software reliability is critical. Evaluate the 1 V minimum operating voltage against the lowest expected system rail to ensure proper functionality under all load conditions.

Supervisors Part Context

This part belongs to the XC6124 series of supervisory circuits from Torex Semiconductor. The series is characterized by low power consumption and compact packaging options suitable for space-constrained designs. The XC6124 variant specifically includes watchdog timer functionality, distinguishing it from basic voltage monitors in the broader product line.

Supervisors Replacement Considerations

Cross-reference with other XC6124 series parts for different threshold voltages or reset delays. Verify pinout compatibility with existing SOT-25-5 footprints before substituting.
