XC6123C544MR-G

Supervisors Overview

The XC6123C544MR-G is a high-precision voltage monitor manufactured by Torex Semiconductor, designed for supervisory circuit applications. It features a fixed detection threshold of 4.4 V with an accuracy of ±2%. The device operates within a supply voltage range of 1.0 V to 6.0 V and consumes a typical static current of 5 uA. It incorporates a built-in watchdog timer and offers selectable release delay times. The output configuration utilizes an N-channel open-drain structure, providing an active-low reset signal. The component is housed in a compact SOT-25-5 surface-mount package, suitable for space-constrained designs.

Supervisors Feature Summary

• Integrates a watchdog timer function with selectable timeout periods for system reliability monitoring
• Features an N-channel open-drain output that actively pulls low upon voltage detection
• Includes internal delay circuits to generate release delay signals without external components
• Supports independent control of the watchdog function via the EN/ENB pin

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 codes against the official datasheet to confirm the exact detection voltage and release delay time settings, as these parameters vary across the XC6123 series. Ensure the ordering part number matches the required threshold and package type. Cross-reference the manufacturer's latest documentation to confirm RoHS compliance status and any updates to the pinout or electrical characteristics before finalizing procurement.

Supervisors Selection Notes

Select this component when a precise 4.4 V threshold is required for voltage supervision. Consider the low static current consumption for battery-powered applications. Verify that the open-drain output interface is compatible with the downstream logic levels. Ensure the operating temperature range of -40°C to +85°C meets the environmental requirements of the target application.
