XC6123F516MR-G

Supervisors Overview

The XC6123F516MR-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 1.6 V. The device utilizes CMOS technology and provides an N-channel open-drain output configuration. Key electrical parameters include a typical operating current of 12 uA and a static current of 5 uA. The component supports a release delay time of 400 ms and functions reliably across an extended temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer function alongside voltage monitoring capabilities within a single CMOS-based supervisory circuit.
• Features an internally pulled-down EN/ENB pin that allows the watchdog function to be disabled while maintaining voltage detection operation when left open.
• Provides precise voltage detection using laser-trimmed internal reference voltages without requiring external components for delay generation.

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 the official datasheet to confirm the exact detection voltage, delay time, and package variant. Ensure compatibility with the target system's voltage levels and thermal requirements before integration. Cross-reference the manufacturer part number with authorized distributors to confirm authenticity and current production status.

Supervisors Selection Notes

Select this component when a combined voltage supervisor and watchdog timer is required in a compact SOT-25-5 package. The low current consumption makes it suitable for battery-powered applications. Verify that the 1.6 V detection threshold aligns with the monitored rail and that the 400 ms release delay meets the system startup timing constraints.

Supervisors Part Context

This part belongs to the XC6123 series of voltage detectors with watchdog functions. The series is characterized by high precision and low current consumption, utilizing advanced CMOS process technology. These devices are designed to provide reliable system supervision in portable and industrial electronics where space and power efficiency are critical design factors.

Supervisors Replacement Considerations

Other parts in the XC6123 series may serve as substitutes if they share the same detection voltage and delay characteristics. Verify pinout compatibility and output configuration before replacement. Consult the manufacturer's cross-reference list for confirmed equivalent part numbers.
