XC6122C440MR-G

Supervisors Overview

The XC6122C440MR-G is a CMOS voltage monitor manufactured by Torex Semiconductor, designed for supervisory circuit applications. It operates within a supply voltage range of 1.0 V to 6.0 V and features a fixed detection threshold voltage of 4.4 V with a typical accuracy of ±2%. The device utilizes an N-channel open-drain output structure that asserts a low-level reset signal when the input voltage falls below the threshold. Key electrical parameters include a maximum operating current of 12 µA and a static current of 5 µA. It incorporates a built-in watchdog timer and supports a release delay time of 50 ms. The component is housed in a compact SOT-25-5 surface-mount package and is rated for operation across an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer function controllable via the EN/ENB pin to prevent system lockups.
• Features a built-in delay circuit that generates release delay signals without requiring external components.
• Utilizes laser-trimmed technology to ensure high precision in the fixed detection voltage setting.

Supervisors Applications

• Power failure detection modules

Supervisors Procurement Notes

Verify the specific suffix codes against the official datasheet to confirm the exact threshold voltage and delay time configuration. Ensure the ordering quantity aligns with the manufacturer's standard packaging requirements. Cross-reference the RoHS compliance status and environmental declarations prior to final procurement decisions.

Supervisors Selection Notes

Select this component when a precise 4.4 V monitoring point is required for single-input voltage supervision. Consider the SOT-25-5 package dimensions for PCB layout constraints. Evaluate the 50 ms release delay duration against the target system's startup timing requirements to ensure stable initialization.

Supervisors Part Context

This part belongs to the XC6122 series of high-precision voltage detectors introduced by Torex Semiconductor. The series employs CMOS processes to achieve low power consumption while maintaining accurate voltage monitoring capabilities for various electronic equipment.

Supervisors FAQ

How is the watchdog timer functionality controlled?

The watchdog timer can be enabled or disabled independently using the EN/ENB pin, allowing the voltage detector to operate while the watchdog is turned off if necessary.

What is the output logic level during normal operation?

The device uses an N-channel open-drain output structure, which outputs a low signal when the monitored voltage drops below the detection threshold.
