XC6123E622ER-G

Supervisors Overview

The XC6123E622ER-G is a high-precision voltage detector with watchdog function and ON/OFF control from the XC6123 series. It features an internal fixed detect voltage of 2.2V, operating voltage range of 1.0V to 6.0V, and N-channel open drain output. The device includes a built-in delay circuit for release delay time settings ranging from 3.13ms to 400ms and six watchdog timeout period options from 50ms to 1.6s. The EN/ENB pin controls the watchdog function on/off state. It operates within -40°C to +85°C temperature range.

Supervisors Feature Summary

• Integrated watchdog timer with selectable timeout periods
• Built-in release delay circuit eliminating external components
• ON/OFF control capability via EN/ENB pin
• High-precision detection voltage using laser trimming technology

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 suffix ER-G corresponds to the USP-6C package and tape & reel packaging configuration. Confirm the detect voltage code E622 aligns with the required 2.2V threshold. Ensure compatibility with the EN/ENB pin internal pull-up/pull-down requirements for watchdog operation. Check RoHS compliance status as indicated in official documentation.

Supervisors Selection Notes

Select this component when a fixed 2.2V detection threshold is required. Consider the USP-6C package size constraints. Evaluate if the available watchdog timeout and delay settings meet system timing requirements. Verify that the N-channel open drain output interface matches the downstream logic level requirements.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors. The XC6123 variant specifically integrates watchdog functionality. The E622 code indicates the specific detect voltage setting within the series' programmable range. The ER-G suffix denotes the specific package and packaging type.

Supervisors FAQ

How is the watchdog function controlled?

The watchdog function can be turned ON or OFF by setting the EN/ENB pin to a low or high level, respectively, while the voltage detector remains operational.

What is the output configuration?

The output configuration is N-channel open drain, which outputs a low signal when the detected voltage falls below the threshold.
