XC6122C737MR-G

Supervisors Overview

The XC6122C737MR-G is a voltage monitor supervisor circuit manufactured by Torex Semiconductor Ltd. It operates within a supply voltage range of 1 V to 6 V and features a detection threshold of 3.7 V. The device utilizes an SOT-25-5 surface-mount package and provides a CMOS open-drain output. Key functional parameters include a reset delay time of 50 ms, a watchdog timer, and battery backup switching capabilities. It supports power failure detection without manual reset functionality. The component operates across a temperature range of -40°C to +85°C with a static current of 5 uA.

Supervisors Feature Summary

• Integrated watchdog timer for system reliability monitoring
• Battery backup switch function for seamless power transition
• Power failure detection capability for critical voltage events
• CMOS open-drain output interface for flexible logic integration

Supervisors Applications

• Portable electronic devices requiring low standby current
• Battery-powered systems with backup power management
• Embedded controllers needing voltage supervision

Supervisors Procurement Notes

Verify the specific threshold voltage and package variant against the official Torex Semiconductor datasheet before procurement. Confirm RoHS compliance status and manufacturing origin requirements. Ensure the ordering suffix matches the exact reel or cut-tape specification needed for your assembly process. Cross-reference the part number with authorized distributors to avoid counterfeit components.

Supervisors Selection Notes

Select this component when a fixed 3.7 V threshold is required for single-input voltage monitoring. Consider the SOT-25-5 package constraints for PCB layout space. Evaluate the 50 ms reset delay against system startup timing requirements. Compare static current consumption against other supervisors if ultra-low power is critical. Verify compatibility with the target system's logic voltage levels.

Supervisors Part Context

This part belongs to the XC6122 series of supervisory circuits from Torex Semiconductor. The series offers various threshold voltages and features like watchdog timers. The XC6122C737MR-G specifically targets applications needing reliable voltage monitoring in compact surface-mount designs. It complements other PMIC solutions by providing dedicated reset generation and power-fail signaling.

Supervisors Replacement Considerations

Direct substitutes may include other XC6122 variants with different threshold voltages, such as XC6122C627MR-G or XC6122C629MR-G, provided the voltage level adjustment meets design needs. Ensure pinout compatibility and package similarity (SOT-25-5) when considering cross-series replacements from other manufacturers.
