XC6121F641ER-G

Supervisors Overview

The XC6121F641ER-G is a high-precision voltage detector with a watchdog function and ON/OFF control, manufactured by Torex Semiconductor using CMOS process technology. It features a fixed detection threshold of 4.1V, an operating voltage range of 1.0V to 6.0V, and a typical supply current of 5µA. The device provides a reset output timeout period of 800ms and a release delay time of 200ms. It operates within a temperature range of -40°C to +85°C and is housed in a compact 6-USP (1.8x2mm) package.

Supervisors Feature Summary

• Integrates a watchdog timer with selectable timeout periods for system monitoring
• Includes an enable pin to control the on/off state of the watchdog function
• Utilizes laser trimming technology for precise internal voltage detection thresholds
• Provides built-in release delay circuitry without requiring external components

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 against the manufacturer's datasheet to confirm the exact package type and environmental compliance status. Ensure the selected part number matches the required detection voltage and timeout period specifications for your application design.

Supervisors Selection Notes

Select this component when a fixed 4.1V threshold is required alongside integrated watchdog functionality. Consider the 6-USP package dimensions for space-constrained designs. Verify that the 800ms timeout aligns with the microprocessor's maximum allowable interrupt response time.

Supervisors Part Context

This part belongs to the XC6121 series of voltage detectors from Torex Semiconductor. The series is characterized by low current consumption and high precision, utilizing CMOS technology. It is designed for applications requiring reliable power management and system reset capabilities in portable and industrial electronics.

Supervisors Replacement Considerations

Cross-reference with other XC6121 variants having different threshold voltages or timeout periods if the 4.1V/800ms configuration does not match requirements. Verify pin compatibility before substituting with other packages in the same family.
