XC6123A747ER-G

Supervisors Overview

The XC6123A747ER-G is a CMOS power management circuit manufactured by Torex Semiconductor Ltd. It functions as a single-channel supervisor and watchdog timer with a fixed threshold voltage of 4.7V. The device utilizes an open-drain or open-collector output configuration for system monitoring. It operates within a temperature range of -40°C to +85°C and is housed in a compact 6-pin USPC package measuring 1.8x2 mm. The component is RoHS compliant and designed for reliable voltage supervision in electronic systems.

Supervisors Feature Summary

• Integrates supervisor and watchdog timer functionalities into a single channel
• Features a fixed 4.7V threshold voltage for precise monitoring
• Provides open-drain or open-collector output compatibility

Supervisors Applications

• Embedded system voltage supervision
• Microcontroller reset circuitry
• Watchdog timer implementation in portable devices

Supervisors Procurement Notes

Verify the specific suffix ER-G against the manufacturer's current datasheet to confirm pinout and electrical characteristics. Ensure the procurement source provides official documentation for the XC6123 series. Confirm RoHS compliance status if required by regulatory standards. Cross-reference the 4.7V threshold requirement with system design specifications before ordering.

Supervisors Selection Notes

Select this component when a fixed 4.7V supervision threshold is required for CMOS logic levels. The integrated watchdog function simplifies design compared to separate supervisor and timer ICs. The small 6-USPC package is suitable for space-constrained applications. Verify that the open-drain output interface matches the downstream microcontroller input requirements.

Supervisors Part Context

This part belongs to the XC6123 series of CMOS power management circuits from Torex Semiconductor. The series focuses on low-power voltage supervision and timing solutions. The XC6123 variants typically offer fixed thresholds optimized for standard logic families. The ER-G suffix indicates the specific package type and environmental compliance status defined by the manufacturer.

Supervisors Replacement Considerations

Direct substitutes include other XC6123 series parts with identical 4.7V thresholds, such as XC6123C547ER-G, provided the package and output configuration match. Verify functional equivalence regarding watchdog timeout periods and operating voltage ranges before substitution.
