XC6121A720ER-G

Supervisors Overview

The XC6121A720ER-G is a high-precision voltage detector with watchdog function manufactured by Torex Semiconductor. It operates within a supply voltage range of 1.6 V to 5.0 V and features a fixed detection threshold of 2.0 V. The device incorporates CMOS process technology, offering low current consumption with an operating current of 12 uA and static current of 5 uA. It provides an open-drain output and includes a built-in delay circuit for release timing without external components. The component supports a watchdog timeout period and functions within an industrial temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer function with ON/OFF control capability via the EN/ENB pin
• Features a built-in delay circuit that eliminates the need for external components for release delay time
• Utilizes laser trimming technology to ensure high precision in internally fixed detection voltages
• Provides low current consumption suitable for battery-powered applications

Supervisors Applications

• Microprocessor reset circuits
• Memory battery backup systems
• System monitoring applications requiring watchdog functionality

Supervisors Procurement Notes

Verify the specific package type and marking code against the official datasheet to ensure compatibility with your PCB footprint. Confirm that the fixed threshold voltage aligns with your system requirements, as adjustable variants are not available for this part number. Check RoHS compliance status and lead times through authorized distributors before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a fixed 2.0 V threshold with integrated watchdog protection is required. Consider the 6-USP package size for space-constrained designs. Ensure the supply voltage remains within the 1.6 V to 5.0 V operational range. Evaluate the 12 uA operating current against power budget constraints for battery-operated devices.

Supervisors Part Context

This part belongs to the XC6121 series, which groups high-precision voltage detectors with watchdog functions. The series utilizes CMOS technology and offers various fixed threshold voltages from 1.6 V to 5.0 V. Different suffixes indicate variations in threshold voltage, output type, and package style within the same functional family.

Supervisors Replacement Considerations

XC6121A720ER-G is part of the XC6121 series. Cross-reference with other XC6121 variants sharing the same USP-6 package and open-drain output if different threshold voltages are needed. Verify pinout compatibility before substituting with other supervisor ICs.
