XC6123C337MR-G

Supervisors Overview

The XC6123C337MR-G is a high-precision voltage monitor from Torex Semiconductor, designed for single-input supervision. It operates within a supply voltage range of 1 V to 6 V and features a fixed detection threshold of 3.7 V. The device incorporates a CMOS open-drain output and includes an integrated watchdog timer with selectable timeout periods ranging from 50 ms to 1.6 s. Release delay times are configurable between 3.13 ms and 400 ms. It consumes a typical static current of 5 uA and operates reliably across a temperature range of -40°C to +85°C in an SOT-25-5 package.

Supervisors Feature Summary

• Integrates a watchdog timer function with multiple selectable timeout periods for system reliability monitoring.
• Features a built-in delay circuit that eliminates the need for external components to generate release delay signals.
• Includes an EN/ENB pin allowing independent control over the watchdog function while maintaining voltage detection operation.

Supervisors Applications

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

Supervisors Procurement Notes

Verify the specific suffix code against the manufacturer datasheet to confirm the exact detection voltage and delay settings. Ensure the ordering quantity aligns with the standard reel packaging requirements specified by Torex Semiconductor. Cross-reference the RoHS compliance status and lead time directly with authorized distributors prior to procurement.

Supervisors Selection Notes

Select this component when a precise 3.7 V threshold is required for supervising low-voltage systems. The inclusion of a watchdog timer makes it suitable for applications requiring automated recovery from software hangs. Consider the SOT-25-5 package size for space-constrained designs and verify that the open-drain output configuration matches the downstream logic interface requirements.

Supervisors Part Context

This part belongs to the XC6123 series of voltage detectors with watchdog functions. The series utilizes CMOS process technology to achieve high precision and low current consumption. Detection voltages are internally fixed using laser trimming technology in increments of 100 mV, ensuring consistent performance across manufacturing batches without requiring external calibration components.

Supervisors Replacement Considerations

Other XC6123 variants with different suffix codes may serve as substitutes if they share the same package and offer compatible electrical characteristics. Verify that alternative parts match the 3.7 V detection threshold and support the required watchdog timeout configurations before implementation.
