XC6123A647MR-G

Supervisors Overview

The XC6123A647MR-G is a high-precision voltage monitor from Torex Semiconductor, packaged in SOT-25-5. It features a fixed detection threshold of 4.7 V and operates within a supply voltage range of 1 V to 6 V. The device includes an integrated watchdog timer with a timeout period of 400 ms and a reset delay time of 3.13 ms. It draws 12 uA during operation and 5 uA in static mode. The output is CMOS open-drain, active low upon detection. It supports power failure detection and battery backup switching without manual reset functionality.

Supervisors Feature Summary

• Integrates a watchdog timer function controllable via the EN/ENB pin while maintaining voltage monitoring operation
• Utilizes laser trimming technology for internally fixed detection voltages with high precision
• Provides built-in release delay circuitry eliminating the need for external timing components

Supervisors Applications

• Microprocessor watchdog monitoring and reset circuits
• Memory battery backup circuits
• System power-on reset circuits
• Power failure detection systems

Supervisors Procurement Notes

Verify the specific suffix MR-G against the manufacturer datasheet to confirm package type and tape/reel specifications. Ensure the 4.7 V threshold aligns with system requirements. Confirm RoHS compliance status through official documentation before integration into production designs.

Supervisors Selection Notes

Select this component when a fixed 4.7 V threshold is required alongside watchdog capabilities. The SOT-25-5 package suits space-constrained surface mount applications. Consider the 400 ms watchdog timeout and 3.13 ms delay characteristics for timing-sensitive microprocessor resets.

Supervisors Part Context

This part belongs to the XC6123 series of voltage detectors with watchdog functions. The series utilizes CMOS process technology to achieve low current consumption. The XC6123 variant specifically offers ON/OFF control for the watchdog function via dedicated pins, distinguishing it from basic voltage monitors.

Supervisors Replacement Considerations

Other XC6123 series variants with different detection voltages or delay times may serve as functional substitutes if electrical parameters are adjusted accordingly.
