XC6121F618ER-G

Supervisors Overview

The XC6121F618ER-G is a voltage detector manufactured by Torex Semiconductor. It features a threshold voltage of 1.8 V and operates within a supply voltage range of 1 V to 6 V. The device provides an open drain output with a reset delay time of 400 ms. It includes a watchdog timer and battery backup switch functionality. The accuracy is specified at 2%. The component supports surface mount installation in a USP-6C package and functions across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system fault recovery
• Includes a battery backup switch function
• Provides open drain output configuration

Supervisors Applications

• System voltage monitoring
• Microprocessor reset circuits
• Battery backup management

Supervisors Procurement Notes

Verify the specific suffix ER-G against official Torex documentation to confirm the USP-6C package type and lead-free status. Ensure the 1.8 V threshold matches the target application requirements. Cross-reference the datasheet for the exact reset delay characteristics and operating temperature limits before finalizing procurement.

Supervisors Selection Notes

Select this component when a fixed 1.8 V detection threshold is required for single-input monitoring. Consider the 400 ms reset delay and open drain output compatibility with downstream logic. Verify that the 6 V maximum input voltage and low static current meet the power budget constraints of the design.

Supervisors Part Context

This part belongs to the XC6121 series of supervisory circuits from Torex Semiconductor. The series offers various threshold voltages and packages. The XC6121F variant specifically denotes the inclusion of a watchdog timer feature, distinguishing it from standard voltage detectors without this timing protection capability.

Supervisors Replacement Considerations

Consult the official XC6121 series cross-reference guide for confirmed substitutes. Verify pinout compatibility and electrical parameter alignment before replacing.
