XC6122F741ER-G

Supervisors Overview

The XC6122F741ER-G is a high-precision voltage detector with an integrated watchdog timer manufactured by Torex Semiconductor. It operates within a supply voltage range of 1.0V to 6.0V and features a fixed detection threshold of 4.1V. The device utilizes CMOS process technology to achieve low current consumption, with a typical operating current of 12µA and standby current of 5µA. It provides a watchdog timeout period of 800ms and a release delay time of 100ms. The output configuration is an N-channel open-drain structure that asserts a reset signal at low level when the input voltage drops below the threshold or the watchdog timer expires. The component is housed in a compact 6-USPC (1.8x2mm) surface-mount package.

Supervisors Feature Summary

• Integrates a watchdog timer function with selectable timeout periods and release delay times without requiring external components.
• Features an EN/ENB pin that allows independent control over the watchdog function while maintaining voltage detection operation.
• Utilizes laser trimming technology to ensure high precision in detection voltage settings across the specified range.
• Employs an N-channel open-drain output driver suitable for interfacing with various logic families.

Supervisors Applications

• Microprocessor watchdog monitoring and reset circuits
• Memory battery backup circuits
• System power-on reset circuits
• Power failure detection systems

Supervisors Procurement Notes

Verify the specific suffix 'ER-G' corresponds to the tape and reel packaging format and RoHS compliance status as defined in the official datasheet. Confirm the detection voltage code matches the required 4.1V threshold for the target application. Ensure the 6-USPC package dimensions align with the PCB footprint requirements. Cross-reference the manufacturer part number with authorized distributors to guarantee authenticity and traceability.

Supervisors Selection Notes

Select this component when a precise voltage monitoring solution with integrated system protection via a watchdog timer is required. The 4.1V threshold makes it suitable for applications where the monitored rail must be tracked closely around standard 3.3V or 5V supplies. Consider the 800ms timeout duration to ensure compatibility with the microcontroller's expected update frequency. The low quiescent current supports battery-operated designs where power efficiency is critical.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors from Torex Semiconductor. The XC6122 variant specifically denotes the inclusion of a watchdog timer function combined with voltage detection capabilities. The series is designed for industrial and consumer electronics requiring reliable power management and system stability through automated reset mechanisms.

Supervisors Replacement Considerations

Compatible substitutes within the same family include XC6122A741ER-G and XC6122E741MR-G, provided the package type and electrical parameters match the design requirements. Verify that alternative parts offer the same 4.1V detection threshold and 800ms watchdog timeout to maintain functional equivalence.
