XC6121E628ER-G

Supervisors Overview

The XC6121E628ER-G is a high-precision voltage detector manufactured by Torex Semiconductor Ltd, belonging to the XC6121 series. It utilizes CMOS process technology and features a fixed detection threshold voltage of 2.8V. The device operates within a supply voltage range of 1.0V to 6.0V and includes a built-in delay circuit that eliminates the need for external components to generate release delay signals. It provides an open-drain output type with low-active reset functionality. The component supports a watchdog timer function and incorporates an ON/OFF control pin (EN/ENB) for power management. It is housed in a compact USP-6 package suitable for surface mount applications.

Supervisors Feature Summary

• Integrates a watchdog timer function alongside voltage monitoring capabilities

Supervisors Procurement Notes

Verify the specific suffix ER-G corresponds to the USP-6 package and RoHS compliance status required for your assembly process. Confirm that the fixed 2.8V threshold aligns with your target voltage monitoring requirements. Ensure compatibility with the 1.0V to 6.0V operating range of your application. Check for any specific handling instructions related to the surface-mount packaging format.

Supervisors Selection Notes

Select this component when a precise 2.8V threshold is required for voltage supervision. Consider its low current consumption characteristics for battery-powered designs. The inclusion of a watchdog timer makes it suitable for applications requiring fault detection beyond simple voltage monitoring. Evaluate the USP-6 package size against available PCB space constraints.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors from Torex Semiconductor. These devices are designed for high-precision monitoring using CMOS technology. The series shares common architectural features such as internal delay circuits and watchdog functions, differing primarily in detection thresholds and package options. This specific model represents a variant optimized for the 2.8V detection level.

Supervisors Replacement Considerations

Direct substitutes within the same series include XC6121E629MR-G and XC6121D629MR-G, which offer similar functionality but may differ in package type or exact threshold tolerance. Verify electrical parameters and pinout compatibility before substitution.
