XC6123A740MR-G

Supervisors Overview

The XC6123A740MR-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 V to 6 V and features a detection threshold of 4.0 V. The device utilizes a CMOS process technology and provides an open-drain output that goes low upon detection. Key electrical parameters include a typical reset delay time of 50 ms, a watchdog timeout of 1.6 s, and a static current consumption of 5 uA. It is housed in a compact SOT-25-5 package and supports operation across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a high-precision voltage detector with a built-in watchdog timer function for comprehensive system supervision.
• Features an ON/OFF control pin (EN/ENB) that allows the watchdog function to be disabled while the voltage detector remains active.
• Provides an open-drain output signal that activates when the monitored voltage falls below the specified threshold.
• Incorporates a built-in delay circuit to generate release delay times without requiring external components.

Supervisors Applications

• Monitoring power supply voltages in portable electronic devices
• System supervision in battery-operated equipment
• Watchdog timer implementation in microcontroller-based circuits

Supervisors Procurement Notes

Verify the specific suffix codes against the official Torex Semiconductor datasheet to ensure correct threshold voltage and package configuration. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer. Ensure the ordering quantity aligns with standard packaging requirements, typically tape and reel formats for this series.

Supervisors Selection Notes

Select this component when a combined voltage monitoring and watchdog timer solution is required in a minimal footprint. The SOT-25-5 package offers space efficiency for surface-mount applications. Consider the 50 ms reset delay and 1.6 s watchdog timeout specifications to match system timing requirements. Verify that the 1 V minimum operating voltage suits the lowest expected supply rail in the target application.

Supervisors Part Context

This part belongs to the XC6123 series of voltage detectors with watchdog functions from Torex Semiconductor. The series is designed using CMOS process technology to achieve low current consumption and high precision. These monitors are intended for applications requiring reliable power management and system reset capabilities in compact electronic designs.

Supervisors Replacement Considerations

Other parts within the XC6123 series may serve as substitutes if they share the same SOT-25 package and compatible electrical characteristics. Verify that alternative candidates offer matching threshold voltages and output configurations before integration.
