CAT1022WI-25-GT3

Supervisors Overview

The CAT1022WI-25-GT3 is a voltage supervisory circuit manufactured by onsemi, designed for CPU supervision applications. It integrates a 2-kbit EEPROM within the supervisor package. The device operates with a single monitored input and features an open-drain output type. Key electrical parameters include a maximum supply voltage of 5.5 V and a reset delay time of 5 µs. The component supports manual reset functionality and lacks a watchdog timer or battery backup switch. It is housed in an SOIC-wide-8 surface-mount package.

Supervisors Feature Summary

• Integrates non-volatile memory storage alongside voltage supervision capabilities
• Provides manual reset control for system recovery
• Features open-drain output configuration for flexible interfacing

Supervisors Applications

• CPU power supply monitoring systems
• Embedded controller reset circuits
• Portable electronic device power management

Supervisors Procurement Notes

Verify component authenticity through authorized distributors due to obsolete status. Confirm package integrity and pin alignment against datasheet specifications. Check for manufacturing date codes relevant to project lifecycle requirements. Ensure RoHS compliance documentation is available for regulatory adherence. Validate that the specific suffix matches design intent as no functional changes are documented for ordering variants.

Supervisors Selection Notes

Select this component when combined supervision and small data storage are required in a compact footprint. Consider the 5 µs reset delay for fast-responding systems. Evaluate the SOIC-8 package constraints against PCB layout limitations. Compare against other CAT1022 variants if different threshold voltages or packages like MSOP are preferred. Verify compatibility with the target microcontroller's reset input requirements.

Supervisors Part Context

This part belongs to the CAT1022 series of supervisory circuits from onsemi. The series typically combines voltage monitoring with embedded EEPROM for storing calibration data or configuration settings. Variants in the family differ primarily by threshold voltage, package style, and specific interface options while maintaining core supervision functions.
