XC6121C725ER-G

Supervisors Overview

The XC6121C725ER-G is a high-precision voltage detector manufactured by Torex Semiconductor Ltd, utilizing CMOS process technology. It features a fixed detection threshold voltage of 2.5V and operates within a supply voltage range of 1.0V to 6.0V. The device incorporates a built-in delay circuit for release delay time control and includes an ON/OFF control function via the EN/ENB pin. It provides an open-drain output that goes low when the detected voltage falls below the threshold. The component is housed in a compact USP-6 package (USP-6C) with dimensions of 1.8mm x 2.0mm. It supports an operating temperature range from -40°C to +85°C and consumes a typical static current of 5µA.

Supervisors Feature Summary

• Integrates a watchdog timer function alongside voltage monitoring capabilities
• Features an internal delay circuit eliminating the need for external timing components
• Includes an enable pin for controlling the watchdog function on and off

Supervisors Applications

• Monitoring power supply voltages in portable electronic devices
• Providing reset signals for microcontrollers and processors during power-up or brown-out events
• Implementing backup battery switching circuits in embedded systems

Supervisors Procurement Notes

Verify the specific suffix 'C725' corresponds to the 2.5V threshold voltage configuration as per the official datasheet. Confirm the package marking and physical dimensions match the USP-6C specification. Ensure compatibility with the required operating temperature range and output logic levels for the target application design.

Supervisors Selection Notes

Select this component when a fixed 2.5V detection threshold is required for single-channel voltage supervision. Consider the integrated watchdog feature if system reliability requires periodic signal verification. Evaluate the low current consumption against battery life requirements. Verify that the open-drain output interface aligns with the input requirements of the connected load or controller.

Supervisors Part Context

This part belongs to the XC6121 series of voltage detectors from Torex Semiconductor. The series is characterized by high precision and low current consumption. The XC6121 variant specifically integrates a watchdog timer function, distinguishing it from basic voltage monitors. The 'C' prefix typically denotes the threshold voltage code, while 'ER-G' indicates the specific package type and environmental compliance status.

Supervisors Replacement Considerations

Cross-reference with other XC6121 series variants such as XC6121C726ER-G or XC6121C724ER-G if different threshold voltages are acceptable. Check for functional equivalents from other manufacturers offering similar USP-6 packaged voltage detectors with watchdog functions.
