XC6121A650ER-G

Supervisors Overview

The XC6121A650ER-G is a high-precision voltage detector with watchdog function and ON/OFF control, manufactured by Torex Semiconductor Ltd using CMOS process technology. It operates within a supply voltage range of 1.6V to 5.0V and features a fixed detection threshold of 5.0V. The device includes an internal delay circuit for release delay times ranging from 3.13ms to 400ms and supports watchdog timeout periods from 50ms to 1.6s. It utilizes an open-drain output type that goes low when detected. The component is housed in a 6-USP (1.8x2) package and functions reliably across an operating temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer function with selectable timeout periods to monitor system activity.
• Features an EN/ENB pin for controlling the ON and OFF states of the watchdog function.
• Incorporates a built-in delay circuit to provide release delay time without external components.
• Utilizes laser trimming technology to ensure high-precision fixed detection thresholds.

Supervisors Applications

• Microprocessor reset circuits
• Memory battery backup systems
• System stability monitoring

Supervisors Procurement Notes

Verify the specific suffix ER-G corresponds to the 6-USP surface-mount package configuration. Confirm the detection threshold is exactly 5.0V as indicated by the model code. Ensure compatibility with the required watchdog timeout and release delay settings for the target application design.

Supervisors Selection Notes

Select this component when a fixed 5.0V threshold is required for power supply monitoring. Consider the integrated watchdog functionality if system fault detection is necessary. Verify that the 6-USP package dimensions fit the available PCB space and that the operating temperature range meets environmental requirements.

Supervisors Part Context

This part belongs to the XC6121 series of voltage detectors from Torex Semiconductor. The series is characterized by low current consumption and high precision. The XC6121 variant specifically provides a watchdog function and manual reset capability, distinguishing it from other series members that may lack these features or offer different output configurations.

Supervisors Replacement Considerations

Cross-reference with other XC6121 variants having the same 5.0V threshold and 6-USP package. Verify functional equivalence regarding watchdog timeout ranges and release delay options before substitution.
