XC6123F541MR-G

Supervisors Overview

The XC6123F541MR-G is a high-precision voltage detector with an integrated watchdog timer, manufactured by Torex Semiconductor using CMOS technology. It monitors a single voltage input within a range of 1.0V to 6.0V, featuring a fixed detection threshold of 4.1V. The device provides an active-low reset output via an open-drain configuration and includes a typical reset timeout period of 400ms. Designed for surface mounting in an SOT-25 package, it operates reliably across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer function with the voltage detector for system monitoring
• Features an EN/ENB pin to independently control the on/off state of the watchdog function
• Utilizes laser trimming technology to ensure high-precision detection voltage stability
• Provides built-in delay circuits eliminating the need for external components for release delays

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 codes against official datasheets to confirm the exact detection voltage and timeout parameters, as these vary across the series. Ensure the ordering suffix matches the required functional configuration. Confirm RoHS compliance status through the manufacturer's documentation before procurement.

Supervisors Selection Notes

Select this component when a combined voltage supervision and watchdog timer is required in a compact form factor. The open-drain output allows for flexible interfacing with various logic levels. Consider the 400ms typical timeout duration to ensure compatibility with the target microcontroller's clock frequency and interrupt response times.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors. The XC6123 variant specifically incorporates a watchdog timer function alongside the voltage monitoring capabilities. The series is characterized by low current consumption and high precision, making it suitable for portable and industrial applications requiring reliable power management.

Supervisors Replacement Considerations

Cross-reference with other XC6123 series variants such as XC6123A541MR-G or XC6123E541MR-G if different detection voltages or timeout periods are needed. Verify that any substitute maintains the same SOT-25 package and electrical characteristics.
