XC6123E517MR-G

Supervisors Overview

The XC6123E517MR-G is a high-precision voltage monitor with watchdog functionality 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 1.7 V. The device utilizes CMOS technology, drawing a typical operating current of 12 µA and a static current of 5 µA. It provides an open-drain output and includes a built-in delay circuit for release timing. Packaged in SOT-25-5, it supports an operating 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 laser-trimmed internal detection voltage settings for high precision
• Includes a built-in delay circuit eliminating the need for external components
• Provides low power consumption suitable for battery-operated systems

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 'E' indicates the correct release delay time setting required for the application design. Confirm the package type matches the PCB footprint requirements. Ensure the detection voltage aligns with the monitored rail level. Check RoHS compliance documentation if environmental regulations apply to the manufacturing process.

Supervisors Selection Notes

Select this component when a fixed 1.7 V threshold is required alongside integrated watchdog protection. Consider the SOT-25-5 package for space-constrained surface-mount designs. Evaluate the 12 µA operating current against system power budgets. Verify that the open-drain output configuration is compatible with the downstream logic levels.

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 current consumption. The XC6123 variants specifically offer ON/OFF control for the watchdog function, allowing independent management of monitoring states while maintaining voltage detection.

Supervisors Replacement Considerations

Other XC6123 models with different suffixes may serve as substitutes if they share the same package and electrical characteristics but differ only in detection voltage or delay time settings.
