XC6122E448MR-G

Supervisors Overview

The XC6122E448MR-G is a CMOS voltage detector manufactured by Torex Semiconductor, designed for power supply monitoring and microprocessor reset management. It operates within a supply voltage range of 1.0 V to 6.0 V with a fixed detection threshold of 4.8 V. The device features a low quiescent current of 5 µA and an operating current of 12 µA. It includes an integrated watchdog timer and provides a CMOS open-drain output. The component is housed in a compact SOT-25-5 package and supports operation across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrated watchdog timer functionality for system reliability
• Low power consumption suitable for battery-operated applications
• Built-in delay circuit eliminates need for external components
• CMOS open-drain output structure for flexible interfacing

Supervisors Applications

• Microprocessor watchdog monitoring and reset circuits
• Memory battery backup switching systems
• Power failure detection mechanisms
• System power-on reset logic

Supervisors Procurement Notes

Verify the specific suffix MR-G corresponds to the SOT-25-5 package configuration when sourcing. Confirm that the E-series designation aligns with the required 4.8 V threshold voltage for your design. Ensure compatibility with standard surface-mount assembly processes given the small outline transistor footprint. Cross-reference official datasheets to validate pinout assignments against your PCB layout requirements.

Supervisors Selection Notes

Select this component when a fixed 4.8 V threshold is required for precise voltage supervision. The SOT-25-5 package offers space efficiency for dense layouts. Consider the 5 µA static current for extended battery life in portable devices. The integrated watchdog feature simplifies design by reducing external component count compared to discrete solutions lacking on-chip timing functions.

Supervisors Part Context

This part belongs to the XC6122 series of high-precision voltage detectors from Torex Semiconductor. The series utilizes CMOS technology to achieve low current consumption while maintaining accurate detection thresholds. These devices are engineered for industrial and consumer electronics requiring reliable power management and system stability through automated reset and monitoring capabilities.

Supervisors Replacement Considerations

Check for XC6122E448MR variants with different packaging suffixes if lead times vary. Verify functional equivalence with other XC6122 series parts sharing the same 4.8 V threshold but differing in package type or thermal characteristics.
