XC6124E638MR-G

Supervisors Overview

The XC6124E638MR-G is a voltage monitor and watchdog timer integrated 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 3.8 V. The device utilizes an open-drain output type and includes a built-in watchdog timer function with a standard reset timeout of 200 ms. It is designed for surface mount installation in a compact SOT-25-5 package. The component supports a backup battery switch function and power failure detection, ensuring reliable system supervision across an operating temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates voltage monitoring with a dedicated watchdog timer for comprehensive system supervision
• Features a low quiescent current consumption suitable for battery-powered applications
• Includes a backup battery switch function to maintain critical data during main power loss

Supervisors Applications

• Portable electronic devices requiring low-power voltage supervision
• Battery-operated systems needing backup switching capabilities
• Embedded controllers utilizing watchdog timer functionality for fault recovery

Supervisors Procurement Notes

Verify the specific threshold voltage code suffix against the official datasheet to ensure compatibility with the target circuit design. Confirm package availability and lead times directly with authorized distributors or the manufacturer, as stock levels fluctuate. Ensure compliance with RoHS and REACH regulations required for your region before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a combined voltage detector and watchdog timer is required in a minimal footprint. The 3.8 V threshold suits applications monitoring 3.3 V or similar logic rails. Consider the open-drain output requirement for pull-up resistor integration. Verify that the 200 ms reset timeout aligns with the system's startup and operational timing constraints.

Supervisors Part Context

This part belongs to the XC6124 series of voltage detectors from Torex Semiconductor. The series is characterized by high precision CMOS technology and low power consumption. The XC6124 variant specifically integrates watchdog timer functions, distinguishing it from basic voltage monitors like the XC6121 or simple detectors like the XC6122. It is part of a broader family offering various threshold voltages and package options.

Supervisors Replacement Considerations

Cross-reference with other XC6124 series parts sharing the same SOT-25-5 package and watchdog functionality. Verify that alternative candidates match the 3.8 V threshold and 200 ms timeout specifications. Ensure pinout compatibility and electrical characteristics such as supply voltage range and output type are identical to prevent redesign efforts.
