XC6121D317MR-G

Supervisors Overview

The XC6121D317MR-G is a voltage detector IC featuring an integrated watchdog timer and ON/OFF control function. It provides a fixed output threshold of 3.175V with high accuracy, ensuring reliable system monitoring. The device operates within a supply voltage range of 0.8V to 6.0V and delivers a low quiescent current of 4.0µA typical. It supports open-drain or open-collector outputs for flexible interface compatibility. The component is housed in a compact SOT-25-5 package, suitable for space-constrained portable electronics.

Supervisors Feature Summary

• Integrated watchdog timer functionality for system fault recovery
• High-precision voltage detection with fixed threshold output
• Low power consumption design for extended battery life
• Flexible output configuration supporting open-drain or open-collector modes

Supervisors Applications

• Portable electronic devices requiring reliable power supervision
• Battery-operated systems needing low standby current
• Industrial equipment with watchdog reset requirements
• Embedded controllers utilizing ON/OFF control signals

Supervisors Procurement Notes

Verify the specific suffix 'MR-G' indicates RoHS compliance and tape-and-reel packaging format as per manufacturer standards. Confirm the operating temperature range matches application requirements. Ensure input voltage does not exceed maximum ratings during transient conditions. Cross-reference pinout assignments with official documentation before PCB layout finalization.

Supervisors Selection Notes

Select this component when precise voltage monitoring combined with watchdog capabilities is required. Consider the fixed 3.175V threshold suitability for target logic levels. Evaluate the SOT-25-5 package constraints against available board space. Assess the low quiescent current benefit for energy-sensitive applications compared to standard supervisors.

Supervisors Part Context

This part belongs to Torex's XC6121 series of voltage detectors. The series is designed for general-purpose power management in portable devices. It complements other Torex regulators by providing essential supervision functions. The model integrates multiple protection features into a single small footprint.

Supervisors Replacement Considerations

Direct substitutes include XC6121D330MR-G (3.300V threshold) and XC6121D350MR-G (3.500V threshold) if different trip points are acceptable. Verify functional equivalence regarding watchdog timeout periods and ON/OFF control polarity. Package compatibility remains consistent across the XC6121 family.
