XC6108N20AMR-G

Supervisors Overview

The XC6108N20AMR-G is a fixed-threshold voltage detector manufactured by Torex Semiconductor using CMOS and laser trimming technologies. It features a separated sense pin, allowing the IC to monitor an added power supply independently from its own VDD. This architecture enables the output to maintain the detection state even if the monitored voltage drops to 0V. The device includes a built-in delay circuit accessible via a dedicated capacitor pin. It operates within a temperature range of -40°C to +85°C and is available in SOT-25 (PDSO5) packaging.

Supervisors Feature Summary

• Separated sense pin allows independent monitoring of external power supplies while maintaining detection state at 0V input.
• Built-in delay circuit with a dedicated pin for connecting external capacitors to set arbitrary release delay times.
• High precision achieved through CMOS manufacturing processes and laser trimming technology.

Supervisors Applications

• Microprocessor reset circuitry
• Charge voltage monitors
• Memory battery back-up switch circuits
• Power failure detection circuits

Supervisors Procurement Notes

Verify the specific suffix AMR corresponds to the SOT-25 package and N-channel open drain output configuration when sourcing. Confirm the threshold voltage matches the required application design, as this model indicates a fixed 2.0V detection level. Ensure compatibility with the intended operating temperature range and check for RoHS compliance status on the specific manufacturer datasheet before final procurement.

Supervisors Selection Notes

Select this component when a voltage detector must monitor a supply rail that may drop to zero without losing its logic state. The separated sense pin is critical for applications where the detector's own power source differs from the monitored line. Consider the external delay capacitor requirement if precise timing control for the release signal is necessary for the system reset sequence.

Supervisors Part Context

This part belongs to the XC6108 series of voltage detectors designed for low power consumption and high accuracy. The series utilizes laser trimming to ensure tight threshold tolerances. The XC6108N20AMR-G specifically denotes the N-channel open drain output variant in the SOT-25 package with a 2.0V threshold, distinguishing it from push-pull or different package variants within the same family.

Supervisors Replacement Considerations

Direct substitutes include other XC6108 series parts with identical package and output type but different thresholds, such as XC6108C20AMR-G if push-pull output is acceptable. Cross-manufacturer equivalents like STM1831 offer similar separated sense functionality but require verification of pinout and electrical characteristics against the original datasheet.

Supervisors FAQ

How does the separated sense pin function compared to standard voltage detectors?

The sense pin is electrically isolated from the IC's power supply pin. This allows the device to monitor an external voltage even if that voltage falls to 0V, whereas standard detectors typically cease operation if their own supply drops below the minimum operating voltage.

What determines the release delay time for this component?

The release delay time is determined by an external capacitor connected to the dedicated delay capacitance pin. The internal circuit uses this capacitor to create an arbitrary delay before the output changes state after the voltage crosses the threshold.
