CAT1024ZI-25-GT3

Supervisors Overview

The CAT1024ZI-25-GT3 is a supervisory circuit manufactured by onsemi, integrating a voltage monitor with a 2-kbit I²C serial EEPROM. It operates within a supply voltage range of 2.7 V to 5.5 V and features a manual reset input with a typical reset delay of 200 ms. The device utilizes an open collector/drain output and supports a 400 kHz I²C bus interface. It is housed in an MSOP-8 package and functions across an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates a precision power supply voltage monitor with a 2-kbit CMOS EEPROM for combined supervision and data storage.
• Supports standard I²C communication protocols with a 400 kHz bus speed for reliable data transfer.
• Includes a manual reset input capability allowing external control over the system reset state.

Supervisors Applications

• CPU supply monitoring in embedded systems
• Data retention in battery-powered devices
• Industrial control system supervision

Supervisors Procurement Notes

Verify current availability status as this component may be subject to discontinuation or limited stock. Confirm RoHS compliance and specific package markings against official datasheets before integration. Check for obsolescence notices from onsemi to ensure long-term supply chain stability for production runs.

Supervisors Selection Notes

Select this part when a compact solution combining voltage supervision and non-volatile memory is required. Ensure the application voltage falls within the 2.7 V to 5.5 V operating range. Verify that the MSOP-8 package fits the PCB layout constraints and that the I²C address configuration meets system requirements.

Supervisors Part Context

This component belongs to the CAT1024 series of supervisory circuits from onsemi. These devices are designed for applications requiring both power management oversight and small-scale data storage. The series typically offers various threshold voltages and package options to suit different system architectures and space limitations.

Supervisors Replacement Considerations

Consult onsemi documentation for direct pin-compatible alternatives within the CAT1024 family. Verify electrical parameters such as reset thresholds and operating temperatures match the original design specifications before substituting.
