XC6123A744MR-G

Supervisors Overview

The XC6123A744MR-G is a voltage monitor circuit manufactured by Torex Semiconductor Ltd, designed for surface-mount installation in SOT-25-5 packages. It features a fixed threshold voltage of 7.44 V and operates within a supply voltage range of 1 V to 6 V. The device provides an open-drain output with low-active reset signaling and includes a standard reset delay time of 200 ms. It incorporates a watchdog timer and battery backup switch functionality while lacking manual reset capability. Operating temperatures span from -40°C to +85°C, with a typical static current of 5 uA and maximum power dissipation of 250 mW.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Includes battery backup switch functionality for power continuity
• Provides open-drain output compatible with CMOS logic levels

Supervisors Applications

• Embedded system power supervision
• Battery-operated device voltage monitoring
• Microcontroller reset circuit generation

Supervisors Procurement Notes

Verify the specific suffix 'A' against official datasheets to confirm threshold voltage accuracy, as suffixes often denote precise voltage tolerances or package variations. Ensure compatibility with SOT-25-5 footprint requirements during PCB layout. Confirm RoHS compliance status through manufacturer documentation prior to integration into regulated environments.

Supervisors Selection Notes

Select this component when a high-voltage threshold near 7.44 V is required for single-input monitoring. Consider the 200 ms reset delay and open-drain output characteristics for interface matching. Evaluate the 5 uA static current consumption against low-power design constraints. Verify that the 6 V maximum operating voltage aligns with the target system's supply rails.

Supervisors Part Context

This part belongs to the XC6123 series of supervisory circuits from Torex Semiconductor. The series offers various threshold voltages and packaging options for power management applications. The XC6123 family typically integrates watchdog and backup functions, distinguishing it from basic voltage detectors. It serves as a specialized solution for systems requiring robust power fault detection and recovery mechanisms.

Supervisors Replacement Considerations

Cross-reference with other XC6123 variants sharing the same package and functional block diagram but differing only in threshold voltage suffixes. Verify pinout compatibility before substituting with similar supervisor ICs from other manufacturers.
