XC6122A725ER-G

Supervisors Overview

The XC6122A725ER-G is a high-precision voltage detector with a watchdog function manufactured by Torex Semiconductor Ltd. It operates within an input voltage range of 1 V to 6 V and features a fixed detection threshold of 2.5 V. The device utilizes CMOS process technology and includes an internal delay circuit for release timing. It offers a watchdog timeout period of 100 ms and a reset delay time of 50 ms. The output configuration is an N-channel open-drain type, suitable for low-current applications with a typical operating current of 12 uA.

Supervisors Feature Summary

• Integrates a watchdog timer function with ON/OFF control capability via the EN/ENB pin
• Provides high-precision voltage detection using laser-trimmed reference voltages
• Features an internal delay circuit eliminating the need for external components for release timing
• Supports battery backup switching and power failure detection operations

Supervisors Applications

• Microprocessor watchdog monitoring and reset circuits
• Memory battery backup circuits
• System power-on reset circuits
• Power failure detection systems

Supervisors Procurement Notes

Verify the specific suffix ER-G corresponds to the USP-6C package and reel packaging format when sourcing. Confirm the detection voltage code matches the required 2.5 V threshold for the target application. Ensure compatibility with the specified operating temperature range of -40°C to +85°C during component selection and validation.

Supervisors Selection Notes

Select this component for applications requiring precise voltage supervision combined with watchdog functionality in a compact surface-mount package. The low current consumption makes it suitable for battery-powered devices. Verify that the open-drain output interface aligns with the system logic levels and pull-up requirements before finalizing the design.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors. These ICs are designed for high-precision monitoring and incorporate CMOS technology. The series provides various detect voltages from 1.6 V to 5.0 V in 0.1 V increments, allowing flexible configuration for different supply rail monitoring needs across industrial and consumer electronics.

Supervisors Replacement Considerations

Cross-reference with other XC6122 series variants such as XC6122A722MR-G or XC6122C620ER-G if package or specific threshold adjustments are needed. Ensure substitute parts maintain the same watchdog timeout and release delay characteristics to preserve system stability.
