XC6123F739ER-G

Supervisors Overview

The XC6123F739ER-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 utilizes a 6-USP (1.8x2 mm) surface-mount package with an exposed pad. The device monitors a single voltage threshold set at 3.9V. It features an active-low reset output with open-drain or open-collector configuration. The typical reset timeout duration is specified as 800 ms, ensuring reliable system supervision for embedded applications requiring precise voltage monitoring and fault recovery mechanisms.

Supervisors Feature Summary

• Integrates voltage detection and watchdog timer functions in a single compact IC
• Provides active-low reset signal with open-drain/open-collector output capability
• Designed for surface-mount assembly in small footprint packages

Supervisors Applications

• Embedded system voltage supervision
• Microcontroller reset circuitry
• Portable electronic device power management

Supervisors Procurement Notes

Verify the complete part number including suffixes against official Torex documentation to ensure correct threshold voltage and package variant. Confirm that the 6-USP package dimensions match your PCB layout requirements. Check operating temperature specifications against your application environment. Ensure compatibility with your system's voltage levels and reset timing requirements before procurement.

Supervisors Selection Notes

Select this component when a combined voltage monitor and watchdog timer is required in a minimal space constraint. The 3.9V threshold suits systems operating near this voltage level. The open-drain output allows flexibility in interfacing with various logic families. Consider the 800ms timeout relative to your processor startup time and watchdog servicing intervals.

Supervisors Part Context

This device belongs to the XC6121/2/3/4 series of supervisors from Torex. These parts are designed for portable equipment and industrial applications requiring reliable power management. The series offers various threshold voltages and package options to accommodate different design needs while maintaining consistent performance characteristics across the family.

Supervisors Replacement Considerations

Consult Torex official documentation for direct pin-compatible substitutes within the XC612x series. Verify equivalent threshold voltages and reset timeouts when considering alternatives. Cross-reference package dimensions and electrical specifications to ensure functional compatibility without redesigning the host circuit.
