XC6121F549MR-G

Supervisors Overview

The XC6121F549MR-G is a voltage detector with watchdog function and ON/OFF control from Torex Semiconductor. It operates within a temperature range of -40°C to 85°C (TA). The device is housed in an SC-74A, SOT-753 package, which corresponds to the SOT-25-5 form factor. It functions as a supervisor circuit designed for monitoring system voltages and providing reset signals.

Supervisors Feature Summary

• Integrates voltage detection with watchdog timer functionality
• Includes ON/OFF control capability for power management
• Utilizes surface mount packaging for compact integration

Supervisors Applications

• System voltage monitoring
• Microcontroller reset circuits
• Watchdog timer applications

Supervisors Procurement Notes

Verify the specific suffix MR-G against the manufacturer datasheet to confirm pinout and tolerance. Ensure the SC-74A/SOT-753 package dimensions match your PCB footprint. Confirm the operating temperature range meets your environmental requirements before finalizing procurement.

Supervisors Selection Notes

Select this component when a combined voltage detector and watchdog timer is required in a small outline transistor package. Consider the -40°C to 85°C industrial temperature range for suitability in broader environmental conditions compared to commercial grade parts.

Supervisors Part Context
