XC6122A350ER-G

Supervisors Overview

The XC6122A350ER-G is a high-precision voltage detector with an integrated watchdog timer manufactured by Torex Semiconductor. It operates within a supply voltage range of 1 V to 6 V and features a fixed detection threshold of 3.5 V. The device utilizes CMOS technology, consuming a typical operating current of 12 µA and a standby current of 5 µA. It provides an N-channel open-drain output and includes a built-in delay circuit for release timing. The watchdog function supports timeout periods ranging from 50 ms to 1.6 s, with release delay times available from 3.13 ms to 400 ms. The component is housed in a compact 6-USPC (UFDFN) package.

Supervisors Feature Summary

• Integrates a high-precision voltage detector with a watchdog timer function using laser-trimmed internal reference voltages.
• Features an enable pin that allows independent control of the watchdog function while maintaining voltage detection operation.
• Provides an N-channel open-drain output configuration suitable for direct interfacing with microprocessor reset lines.
• Eliminates the need for external components for delay circuits due to built-in release delay and watchdog timeout mechanisms.

Supervisors Applications

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

Supervisors Procurement Notes

Verify the specific suffix 'A' indicates the correct 3.5 V detection threshold and 'ER' denotes the 6-USPC tape-and-reel packaging. Confirm RoHS compliance status through official manufacturer documentation. Ensure the selected variant matches the required watchdog timeout period and release delay time specifications for the target application design.

Supervisors Selection Notes

Select this component when a low-current supervisory circuit with integrated watchdog functionality is required. The fixed 3.5 V threshold suits applications monitoring standard logic or memory supply rails. Verify that the 1 V minimum operating voltage aligns with the system's lowest expected supply level. Consider the open-drain output requirement for pull-up resistor integration in the circuit design.

Supervisors Part Context

This part belongs to the XC6122 series, which groups high-precision voltage detectors with watchdog functions. The series differentiates parts by detection voltage thresholds, packaged in various small form factors. The XC6122 specifically targets applications requiring both voltage supervision and processor watchdog protection in a single compact IC solution.

Supervisors Replacement Considerations

Cross-reference other XC6122 variants with different detection voltages if the 3.5 V threshold does not match the system rail. Verify package compatibility when substituting with other suffixes in the XC6122 family. Ensure equivalent watchdog timeout and release delay characteristics are maintained during replacement.
