XC6123F537MR-G

Supervisors Overview

The XC6123F537MR-G is a high-precision voltage detector with watchdog functionality manufactured by Torex Semiconductor. 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 utilizes an N-channel open-drain output configuration and includes a built-in release delay circuit. Key specifications include a typical operating current of 12 µA and a static current of 5 µA. It supports a watchdog timeout period ranging from 50 ms to 1.6 s and offers selectable release delay times. The component is housed in a compact SOT-25-5 package and is rated for operation between -40°C and +85°C.

Supervisors Feature Summary

Supervisors Procurement Notes

Verify the specific suffix codes against the official datasheet to confirm the exact detection voltage and release delay time settings. Ensure the ordering quantity aligns with the manufacturer's standard packaging requirements. Cross-reference the RoHS compliance status and environmental declarations with the latest documentation provided by Torex Semiconductor before finalizing procurement.

Supervisors Selection Notes

Select this component when a single-channel voltage monitor with integrated watchdog protection is required. The fixed 3.7 V threshold makes it suitable for systems where this specific voltage level serves as the critical reference point. Consider the SOT-25-5 package size for space-constrained designs. Verify that the 12 µA operating current meets the system's power budget constraints during active monitoring phases.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors. These devices are designed for high-precision monitoring applications using CMOS technology. The series distinguishes itself through configurable watchdog functions and internal delay circuits, eliminating the need for external timing components. This specific model represents one variant within the family defined by its unique threshold and delay characteristics.

Supervisors Replacement Considerations

Other models within the XC6123 series may serve as substitutes if they share the same SOT-25-5 package and compatible electrical parameters. Verify that alternative parts match the 3.7 V detection threshold and similar current consumption profiles. Ensure any replacement maintains the N-channel open-drain output configuration and compatible operating temperature range.
