XC6122C238MG-G

Supervisors Overview

The XC6122C238MG-G is a CMOS voltage detector manufactured by Torex Semiconductor Ltd, designed for power management applications. It features a single monitored input with a detection threshold of 3.8V. The device provides an open-drain output and generates a reset signal that is active low. It includes a standard reset timeout of 50ms to ensure stable system recovery. Operating within a supply voltage range of 1.0V to 6.0V, it supports surface mount installation in a compact SOT-25-5 package. The component operates reliably across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides precise voltage monitoring with a fixed 3.8V detection threshold for reliable power supervision.
• Features an open-drain output configuration compatible with various logic families for flexible interface integration.
• Incorporates a built-in reset delay timer to prevent false triggering during power-up transients.

Supervisors Applications

• Battery-powered portable electronic devices requiring low standby current
• Microcontroller and digital circuit power supply supervision
• Embedded systems needing reliable reset generation upon power loss

Supervisors Procurement Notes

Verify the specific suffix 'MG-G' against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS status. Ensure the ordering code matches the required threshold voltage and package type exactly. Cross-reference with official distributor catalogs to validate current availability and lead times before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a fixed 3.8V threshold is required for single-channel voltage monitoring. It is suitable for designs prioritizing low quiescent current and compact SOT-25 footprint. Consider alternative thresholds if the target supply voltage differs significantly from the 3.8V trip point. Verify that the open-drain output architecture aligns with the downstream logic requirements.

Supervisors FAQ

What is the reset output polarity of the XC6122C238MG-G?

The reset output is active low, meaning the output goes low when the monitored voltage drops below the detection threshold.

Does the XC6122C238MG-G include a manual reset function?

No, the XC6122C238MG-G does not support manual reset; it relies solely on automatic voltage detection for reset generation.
