XC6123A544MR-G

Supervisors Overview

The XC6123A544MR-G is a high-precision voltage detector with watchdog function manufactured by Torex Semiconductor. It operates within a supply voltage range of 1 V to 6 V and features a fixed detection threshold of 4.4 V. The device incorporates an N-channel open-drain output and supports a release delay time of 50 ms. It includes a watchdog timer with selectable timeout periods ranging from 50 ms to 1.6 s, controllable via the EN/ENB pin. The component functions in temperatures from -40°C to +85°C, consumes 5 µA static current, and is housed in an SOT-25-5 package.

Supervisors Feature Summary

• Integrates a watchdog timer with selectable timeout periods for system monitoring
• Features an EN/ENB pin to independently control the watchdog function state
• Utilizes laser trimming technology for precise internal detection voltage settings
• Provides built-in delay circuits eliminating the need for external components

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 codes against official datasheets to confirm exact threshold voltages and package variations. Ensure compatibility with required operating temperature ranges and supply voltage limits before integration. Cross-reference manufacturer part numbers to avoid confusion with similar series variants that may have different electrical characteristics or pin configurations.

Supervisors Selection Notes

Select this component when a dedicated voltage monitor with integrated watchdog functionality is required. It is suitable for applications needing precise threshold detection without external timing components. Consider the low static current consumption for battery-operated systems. Verify that the open-drain output configuration aligns with the downstream logic requirements of the target circuit design.

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. These devices are designed to replace discrete solutions by integrating reference sources, comparators, and delay circuits into a single compact package, simplifying board layout and reducing component count.

Supervisors Replacement Considerations

Check for XC6123 series variants with identical 4.4 V thresholds and SOT-25 packaging. Confirm functional equivalence regarding watchdog timeout options and EN/ENB pin behavior. Verify that alternative parts maintain the same operating voltage range and temperature specifications.
