XC6123D734MR-G

Supervisors Overview

The XC6123D734MR-G is a high-precision voltage detector with watchdog function and ON/OFF control manufactured by Torex Semiconductor. It operates within a supply voltage range of 1.6V to 5.0V and features a typical threshold voltage of 3.4V. The device provides an active low reset output with an open-drain or open-collector configuration. It includes a watchdog timer with a typical timeout period of 800 ms. The component is designed for surface mounting in a SOT-25 package and supports an operating temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates voltage detection with watchdog timer functionality for system stability
• Features ON/OFF control capability for power management optimization
• Provides active low reset signal via open-drain/open-collector output
• Operates across a wide input voltage range suitable for various logic levels

Supervisors Applications

• Microprocessor reset circuits requiring watchdog monitoring
• Battery-powered devices needing voltage supervision and power control
• Embedded systems ensuring reliable operation under varying supply conditions
• Industrial equipment requiring robust voltage detection in harsh environments

Supervisors Procurement Notes

Verify the specific suffix MR-G corresponds to the SOT-25 packaging and tape & reel delivery format. Confirm that the D734 designation accurately reflects the 3.4V threshold requirement for your application. Ensure compatibility with the specified operating temperature range of -40°C to +85°C. Cross-reference the datasheet revision to confirm pinout consistency with existing designs.

Supervisors Selection Notes

Select this component when both voltage monitoring and watchdog timing are required in a single IC. The 3.4V threshold suits applications where the supply rail typically exceeds this value. Consider the SOT-25 package size constraints and the need for an active low reset signal. Verify that the 800ms watchdog timeout aligns with the system's maximum allowable response time before intervention.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors. These components share similar architectures but differ in threshold voltages, output types, and package options. The XC6123 variant specifically integrates the watchdog function alongside voltage detection, distinguishing it from simpler supervisors in the same family.

Supervisors Replacement Considerations

Check for other XC6123 series parts with different threshold voltages if 3.4V is not exact. Verify pin-to-pin compatibility with alternative vendors offering similar watchdog supervisors. Ensure the replacement maintains the active low reset polarity and open-drain output structure.
