XC6123C527MR-G

Supervisors Overview

The XC6123C527MR-G is a high-precision voltage monitor with an integrated watchdog timer manufactured by Torex Semiconductor. It operates within a supply voltage range of 1.0 V to 6.0 V and features a fixed detection threshold of 2.7 V. The device utilizes CMOS technology, drawing a typical operating current of 12 µA and a static current of 5 µA. It provides a CMOS open-drain output and includes a backup battery switch function. The reset delay time is specified at 200 ms, and it functions reliably across an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer with ON/OFF control capability via the EN/ENB pin
• Features low current consumption suitable for battery-powered applications
• Includes a built-in delay circuit eliminating the need for external components
• Provides power failure detection with a backup battery switch function

Supervisors Applications

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

Supervisors Procurement Notes

Verify the specific suffix MR-G confirms the SOT-25-5 surface-mount package and tape-and-reel factory packaging configuration. Confirm the C-series designation aligns with the required 2.7 V threshold voltage and standard tolerance specifications. Ensure compatibility with the target system's voltage levels and temperature requirements before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a precise 2.7 V detection threshold is required alongside integrated watchdog functionality. The low quiescent current makes it appropriate for energy-constrained designs. Verify that the open-drain output interface matches the microcontroller or logic gate input requirements of the host system architecture.

Supervisors Part Context

This part belongs to the XC6123 series of voltage detectors with watchdog functions. The series employs CMOS process technology to achieve high precision and low power consumption. It is designed for supervisory applications where reliable monitoring of power rails and system timing integrity are critical for operational stability.

Supervisors Replacement Considerations

Cross-reference other XC6123 variants with identical 2.7 V thresholds and compatible packages. Verify functional equivalence regarding watchdog timeout periods and reset delay times before substitution.
