XC6123D426MR-G

Supervisors Overview

The XC6123D426MR-G is a high-precision voltage monitor with an integrated watchdog timer manufactured by Torex Semiconductor. It operates within a supply voltage range of 1.0 V to 6.0 V and features a fixed detection threshold of 2.6 V. The device utilizes CMOS technology, drawing a typical operating current of 12 µA and a static current of 5 µA. It provides an active-low open-drain output with a standard reset delay time of 200 ms. Packaged in a compact SOT-25-5 format, it supports surface-mount installation and functions reliably across an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates a high-precision voltage detector with a built-in watchdog timer for comprehensive system supervision.
• Features an EN/ENB control pin that allows independent disabling of the watchdog function while maintaining voltage monitoring.
• Utilizes CMOS process technology to achieve low power consumption suitable for battery-operated applications.
• Provides an active-low open-drain output signal without requiring external components for delay timing.

Supervisors Applications

• Microprocessor watchdog circuits and reset management
• Memory battery backup systems
• Power failure detection in electronic equipment

Supervisors Procurement Notes

Verify the specific suffix code against official documentation to confirm the exact threshold voltage and delay characteristics, as these parameters vary significantly across the XC6123 series. Ensure the ordering quantity aligns with the manufacturer's standard packaging requirements. Cross-reference the RoHS compliance status directly with the latest datasheet before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when a single-input voltage monitor with integrated watchdog functionality is required. The 2.6 V threshold makes it suitable for monitoring 3.3 V or similar logic supply rails. Consider the 12 µA operating current for low-power designs. Verify that the SOT-25 package fits the board space constraints and that the open-drain output interface matches the downstream circuitry requirements.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors with watchdog functions. The series is characterized by high precision and low current consumption, utilizing laser-trimmed reference voltages. These devices are designed to replace discrete comparator-based solutions, offering a compact footprint and simplified design through integrated delay circuits and control pins.

Supervisors Replacement Considerations

XC6123E426MR-G: Offers identical electrical specifications and pinout but may differ in manufacturing lot or minor tolerance variations.
