XC6124A739MR-G

Supervisors Overview

The XC6124A739MR-G is a high-precision voltage detector with a watchdog timer manufactured by Torex Semiconductor. It utilizes CMOS technology and features an open-drain output active low. The device monitors a single voltage channel with a threshold of 3.9V. It operates within a supply voltage range of 1.6V to 5.0V and supports an operating temperature range of -40°C to +85°C. The reset timeout is typically 800ms, and it is housed in a SOT-25-5 package.

Supervisors Feature Summary

• Integrates a watchdog timer function with an ON/OFF control pin for flexible system management
• Provides high-accuracy voltage detection using advanced CMOS process technology
• Features an open-drain output that signals when the monitored voltage falls below the threshold

Supervisors Applications

• Embedded systems requiring power supervision and automatic reset capabilities
• Microcontroller unit (MCU) monitoring circuits with watchdog functionality
• Battery-powered devices needing low current consumption voltage detection

Supervisors Procurement Notes

Verify the specific suffix MR-G against the manufacturer's latest datasheet to confirm package type and electrical characteristics. Ensure compatibility with the target system's voltage levels and temperature requirements before procurement. Cross-reference the part number with authorized distributors to avoid counterfeit components.

Supervisors Selection Notes

Select this component when a combined voltage supervisor and watchdog timer is required in a compact surface-mount package. The 3.9V threshold suits applications monitoring standard logic or battery voltages. Consider the open-drain output requirement for pull-up resistor integration in the design.

Supervisors Part Context

This part belongs to the XC6124 series of voltage detectors with watchdog functions. The series is designed for high precision and low current consumption, making it suitable for portable electronics. The XC6124A739MR-G specifically denotes a 3.9V threshold variant in the SOT-25-5 package.

Supervisors Replacement Considerations

Check for other XC6124 variants with different thresholds if the 3.9V setting does not match the application needs. Verify pinout compatibility with alternative supervisors from the same family or other manufacturers offering similar watchdog timer ICs in SOT-25 packages.
