XC6121A337ER-G

Supervisors Overview

The XC6121A337ER-G is a high-precision voltage detector with watchdog functionality manufactured by Torex Semiconductor. It utilizes CMOS process technology and operates within a supply voltage range of 1.6V to 5.0V. The device features a fixed detection threshold of 3.3V, ensuring accurate monitoring of power supply levels. It incorporates an internal delay circuit that eliminates the need for external components to generate release delay signals. The output driver provides a low signal when the detected voltage falls below the threshold. The component is housed in a compact 6-pin USP package.

Supervisors Feature Summary

• Integrates a watchdog timer function alongside standard voltage detection capabilities
• Includes an internal delay circuit for generating release delay times without external parts
• Features an EN/ENB pin for controlling the ON/OFF state of the watchdog function

Supervisors Applications

• Monitoring power supply voltages in industrial equipment
• System reset generation for electronic devices
• Watchdog timer implementation in microcontroller circuits

Supervisors Procurement Notes

Verify the specific suffix ER-G corresponds to the required packaging format and environmental compliance status. Confirm the detection threshold matches the system requirement of 3.3V. Ensure the operating temperature range aligns with the application environment constraints. Cross-reference the datasheet revision to confirm pinout compatibility.

Supervisors Selection Notes

Select this component when a fixed 3.3V threshold is required for voltage monitoring. Consider the integrated watchdog feature if system reliability against software hangs is critical. Evaluate the low current consumption characteristics for battery-operated applications. Verify that the open-drain output type suits the logic level requirements of the connected microcontroller.
