XC6124D329MR-G

Supervisors Overview

The XC6124D329MR-G is a high-precision voltage detector manufactured by Torex Semiconductor Ltd using CMOS technology. It features an integrated watchdog timer and ON/OFF control functionality within a compact SOT-25-5 package. The device monitors input voltages with a fixed detection threshold of 2.9V, utilizing laser trimming for accuracy. It operates within a supply voltage range of 1.0V to 6.0V and includes a built-in delay circuit that eliminates the need for external components. The output driver provides a low-active signal upon voltage detection.

Supervisors Feature Summary

• Integrates a watchdog timer function controllable via the EN/ENB pin
• Utilizes laser trimming technology for precise internal voltage detection thresholds
• Incorporates a built-in delay circuit to generate release delay signals without external parts

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 'D' indicates the correct detection voltage variant (2.9V) against system requirements. Confirm the 'MR-G' designation corresponds to the SOT-25-5 surface mount package and RoHS compliance status. Ensure compatibility with the required operating temperature range of -40°C to +85°C before finalizing procurement specifications.

Supervisors Selection Notes

Select this component when a single-channel supervisor with integrated watchdog capabilities is required. The fixed 2.9V threshold suits applications where this specific voltage level triggers the reset or alarm state. The open-drain output configuration allows for flexible interfacing with various logic families. Consider the low current consumption characteristics if battery life is a critical design constraint.

Supervisors Part Context

This part belongs to the XC6124 series of voltage detectors from Torex Semiconductor. The series is characterized by high precision and low current consumption achieved through advanced CMOS process technology. These devices are designed to provide reliable supervision for digital systems, combining voltage monitoring with watchdog functions in a space-saving footprint suitable for portable electronics.

Supervisors Replacement Considerations

Cross-reference with other XC6124 variants such as XC6124C329MR-G or XC6124A329MR-G to verify package and hysteresis differences. Ensure any substitute maintains the same 2.9V detection threshold and SOT-25-5 form factor. Verify that the replacement supports the necessary watchdog timeout periods and ON/OFF control logic levels.
