XC6122D338ER-G

Supervisors Overview

The XC6122D338ER-G is a high-precision voltage detector with watchdog function manufactured by Torex Semiconductor. It operates within a supply voltage range of 1.0 V to 6.0 V and features a fixed detect voltage of 3.3 V. The device utilizes CMOS process technology, consuming a typical operating current of 12 uA and a static current of 5 uA. It includes an N-channel open drain output and supports a watchdog timeout period of 100 ms. The component is housed in a 6-USPC (1.8x2) package.

Supervisors Feature Summary

• Integrates a watchdog timer for system monitoring alongside voltage detection capabilities
• Features low current consumption suitable for battery-powered applications
• Includes built-in delay circuit eliminating the need for external components

Supervisors Applications

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

Supervisors Procurement Notes

Verify the specific detect voltage threshold and watchdog timeout configuration against the official datasheet before procurement. Confirm that the 6-USPC package dimensions align with the target PCB footprint. Ensure the supply voltage range meets the application requirements. Check RoHS compliance status if required by project specifications.

Supervisors Selection Notes

Select this component when a combined voltage supervisor and watchdog timer is required in a compact surface-mount package. The low quiescent current makes it appropriate for energy-efficient designs. Verify that the fixed 3.3 V detection threshold matches the monitored rail voltage. Consider the open-drain output compatibility with the downstream logic levels.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors from Torex Semiconductor. The series is characterized by high precision and low current consumption. The XC6122 variant specifically incorporates a watchdog function controlled via an EN/ENB pin, allowing independent management of the watchdog state while the voltage detector remains active.

Supervisors Replacement Considerations

Other parts within the XC6122 series may serve as functional substitutes if they match the required detect voltage and package type. Cross-reference the electrical parameters and pinout configuration carefully to ensure compatibility.
