CAT1024ZI-42-GT3

Supervisors Overview

The CAT1024ZI-42-GT3 is a voltage supervisory circuit manufactured by onsemi, designed for CPU supervision applications. It integrates a 2Kb EEPROM with the supervisor functionality. The device operates within a supply voltage range of 2.7 V to 5.5 V and features an under-voltage threshold of 4.25 V. It utilizes an MSOP-8 surface-mount package and supports manual reset input. The component includes a watchdog timer function and provides an open collector/drain output type. It is rated for operation between -40°C and +85°C.

Supervisors Feature Summary

• Integrates 2Kb EEPROM memory with voltage supervision capabilities
• Supports manual reset input for system control
• Includes built-in watchdog timer functionality
• Provides open collector or drain output configuration

Supervisors Applications

• CPU power supply monitoring
• Embedded system reset management
• Industrial control board supervision

Supervisors Procurement Notes

Verify end-of-life status before design finalization as this component may be discontinued. Confirm availability through authorized distributors only. Check current datasheet revisions for any parameter updates. Ensure MSOP-8 footprint compatibility with existing PCB layouts. Validate operating temperature ranges against specific application requirements.

Supervisors Selection Notes

Compare against CAT1024 series variants for different package options like TSSOP-8 or SOIC-Wide-8. Consider CAT1027 series if automatic reset without manual input is preferred. Evaluate CAT1022 series for lower quiescent current needs. Verify EEPROM size requirements against other family members. Assess threshold voltage accuracy needs against available options.

Supervisors Part Context

This part belongs to the CAT1024 series of supervisory circuits from onsemi. The series combines microcontroller supervision with non-volatile memory storage. Similar parts include CAT1024YI-42-GT3 in TSSOP-8 and CAT1024WI-42-GT3 in SOIC-Wide-8 packages. All share similar electrical characteristics but differ in physical form factors.

Supervisors Replacement Considerations

CAT1024YI-42-GT3 offers identical functionality in a TSSOP-8 package. CAT1024WI-42-GT3 provides the same specs in an SOIC-Wide-8 package. These are direct pin-compatible alternatives within the same product family.
