XC6124C642ER-G

Supervisors Overview

The XC6124C642ER-G is a voltage monitor IC from Torex Semiconductor, designed for supervising single-channel power supplies. It features a detection threshold of 4.0 V and operates within a supply voltage range of 1.0 V to 6.0 V. The device utilizes a CMOS open-drain output and includes a reset delay time of 200 ms. It incorporates a watchdog timer function and supports battery backup switching. The component is housed in a compact 6-USPC (1.8x2) surface-mount package. It functions reliably across an extended temperature range from -40°C to +85°C, with a maximum power dissipation of 250 mW.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Supports battery backup switching functionality
• Features a dedicated sense pin separate from the power supply pin

Supervisors Applications

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

Supervisors Procurement Notes

Verify the specific suffix 'G' indicates RoHS compliance as per manufacturer standards. Confirm the 6-USPC package dimensions match your PCB footprint requirements. Ensure the 4.0 V threshold aligns with your target rail voltage. Check datasheet for precise reset delay tolerances and operating current specifications before finalizing the bill of materials.

Supervisors Selection Notes

Select this component when a low-voltage supervisor with integrated watchdog capabilities is required. The 6-USPC package offers space efficiency for dense layouts. Consider the 200 ms reset delay for timing-sensitive applications. Verify that the 1.0 V minimum operating voltage suits your lowest expected supply level. The CMOS open-drain output requires appropriate pull-up resistor selection for logic compatibility.

Supervisors Part Context

This part belongs to the XC6124 series of simple integration voltage detectors. These devices are characterized by high precision and low power consumption. The series leverages advanced CMOS technology to achieve accurate voltage monitoring. The XC6124C642ER-G specifically denotes the 4.0 V threshold variant within this family.

Supervisors Replacement Considerations

XC6124C640ER-G serves as a direct substitute with a different threshold voltage.
