XC6124C544MR-G

Supervisors Overview

The XC6124C544MR-G is a high-precision voltage monitor from Torex Semiconductor, packaged in an SOT-25-5 surface-mount case. It features a fixed detection threshold of 5.4 V and operates within a supply voltage range of 1 V to 6 V. The device incorporates a built-in watchdog timer with a typical reset delay time of 50 ms. It draws an operating supply current of 12 µA and maintains a low static current of 5 µA. The output driver provides an N-channel open drain configuration. It supports power failure detection and battery backup switching functions without requiring manual reset or external components for delay timing.

Supervisors Feature Summary

• Integrates a watchdog timer function controllable via the EN/ENB pin
• Utilizes laser trimming technology for precise internal voltage detection settings
• Provides open-drain output that goes low upon voltage detection
• Operates with minimal external component requirements due to built-in delay circuits

Supervisors Applications

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

Supervisors Procurement Notes

Verify the specific suffix MR-G against the manufacturer's official datasheet to confirm package type and tape/reel specifications. Ensure the detection voltage code matches the required system threshold. Confirm RoHS compliance status through the latest product documentation before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a fixed 5.4 V detection threshold is required for single-input monitoring. Consider the 12 µA operating current for low-power applications. Verify that the open-drain output interface is compatible with the downstream logic levels. Ensure the operating temperature range meets the environmental requirements of the target application.

Supervisors Part Context

This part belongs to the XC6124 series of voltage detectors with watchdog functions. The series utilizes CMOS process technology to achieve high precision and low current consumption. The XC6124 variants are designed for supervisory circuit applications where reliable power monitoring and processor reset management are critical.

Supervisors Replacement Considerations

Cross-reference with other XC6124 series parts having different detection voltages if the threshold does not match. Verify compatibility with XC6122 series devices for similar functionality but different pinout or feature sets.
