CAT1022WI-30-GT3

Supervisors Overview

The CAT1022WI-30-GT3 is a voltage supervisory circuit manufactured by onsemi, designed for CPU supervision applications. It integrates a 2-kilobit EEPROM within the supervisory logic. The device operates with a maximum supply voltage of 5.5 V and features a threshold voltage of 3 V. It utilizes an open-drain output type and includes a manual reset function alongside a watchdog timer. The reset delay time is specified at 200 ms. The component is housed in an SOIC-wide-8 surface-mount package.

Supervisors Feature Summary

• Integrates non-volatile 2-kilobit EEPROM for data storage alongside supervisory functions
• Includes built-in watchdog timer to monitor system operation stability
• Supports manual reset input for user-initiated system recovery

Supervisors Applications

• CPU power supply monitoring in embedded systems
• Data retention management via integrated EEPROM
• System reset generation in microcontroller circuits

Supervisors Procurement Notes

Verify component authenticity through authorized channels as this part is listed as obsolete. Confirm package integrity and pin alignment against the SOIC-wide-8 specification. Review datasheet revisions for any historical parameter updates prior to integration into new designs.

Supervisors Selection Notes

Select this component when both voltage supervision and small-scale data storage are required in a single package. Ensure the 3 V threshold aligns with the target supply rail. Verify that the SOIC-wide-8 footprint fits the PCB layout constraints compared to standard SOIC packages.

Supervisors Part Context

This part belongs to the CAT1022 series of supervisory circuits from onsemi. It combines power management monitoring with memory capabilities, distinguishing it from pure supervisor ICs. The WI suffix indicates the wide-body SOIC package variant, while the 30 denotes the specific voltage threshold setting.

Supervisors Replacement Considerations

Check for direct cross-references in distributor databases. Consider CAT1022 variants with different thresholds or packages if exact matches are unavailable. Evaluate alternative supervisors with external EEPROM if internal memory is not strictly required.
