XC6123D739ER-G

Supervisors Overview

The XC6123D739ER-G is a voltage detector and watchdog timer integrated circuit manufactured by Torex Semiconductor. It operates within an ambient temperature range of -40°C to +85°C and is housed in a compact 6-USP (1.8x2 mm) surface-mount package with an exposed pad. The device monitors a single voltage rail, featuring a threshold of 3.9V. It provides an active-low reset output via an open-drain or open-collector configuration. The typical reset timeout duration is 800 ms, ensuring reliable system supervision for embedded applications requiring precise voltage monitoring and fault recovery.

Supervisors Feature Summary

• Integrates voltage detection and watchdog timer functions in a single component
• Provides active-low reset signal with open-drain/open-collector output capability
• Designed for surface-mount assembly in space-constrained environments

Supervisors Applications

• Embedded systems requiring voltage supervision
• Microcontroller reset circuits
• Portable electronic devices

Supervisors Procurement Notes

Verify the specific suffix 'D' against official Torex documentation to confirm pinout and functional variations compared to other series variants. Ensure the 6-USP package dimensions align with PCB footprint requirements. Confirm operating temperature range specifications match application environmental conditions before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when both voltage monitoring and watchdog functionality are required in a minimal footprint. The 3.9V threshold suits applications where supply voltage stability around this level is critical. Consider the open-drain output compatibility with downstream logic levels. Evaluate the 800 ms timeout against system startup and fault recovery timing requirements.

Supervisors Part Context

This part belongs to the XC6123 series of supervisors from Torex. The series offers various threshold voltages and package options. The XC6123D739ER-G specifically denotes the 3.9V threshold variant in the 6-USP package. It is part of the PMIC Supervisors family, designed for power management integrity in consumer and industrial electronics.

Supervisors Replacement Considerations

Cross-reference with XC6123 series equivalents from Torex for different thresholds or packages. Verify pin-to-pin compatibility if substituting with other manufacturers' voltage detectors. Ensure watchdog timeout characteristics match system requirements when considering alternative components.
