XC6122F541MR-G

Supervisors Overview

The XC6122F541MR-G is a high-precision voltage detector with watchdog function and ON/OFF control, manufactured by Torex Semiconductor. It operates within an input voltage range of 1 V to 6 V and features a fixed detection threshold of 4.1 V. The device utilizes CMOS process technology and provides an N-channel open-drain output that goes low upon detection. Key electrical parameters include a typical operating supply current of 12 uA and a static current of 5 uA. The reset delay time is specified at 200 ms, and the watchdog timeout period is selectable from 50 ms to 1.6 s. It functions reliably across an operating temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer with selectable timeout periods for system monitoring
• Includes an EN/ENB pin to independently control the watchdog function while maintaining voltage detection
• Features laser-trimmed internal reference voltages for high precision without external components
• Provides built-in release delay circuitry to prevent false triggering during power transitions

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 MR-G against the manufacturer's official datasheet to confirm package type and tape/reel specifications. Ensure the detection voltage code matches the required 4.1 V threshold for your application. Cross-reference RoHS compliance status directly with the latest product documentation before procurement.

Supervisors Selection Notes

Select this component when a single-input voltage monitor with integrated watchdog functionality is required. The 4.1 V threshold suits applications monitoring higher voltage rails. Consider the 12 uA operating current for low-power designs. Verify that the SOT-25-5 package fits the PCB layout constraints and that the open-drain output compatibility matches the downstream logic levels.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors. These ICs are designed for high-precision monitoring using CMOS technology. The series distinguishes itself by combining voltage detection with watchdog timers and enable controls in a compact surface-mount package, eliminating the need for external timing components.

Supervisors Replacement Considerations

Check for other XC6122 variants with different detection voltages or delay times if the 4.1 V threshold is unsuitable. Verify pinout compatibility with existing designs when substituting with similar supervisor ICs from other manufacturers.
