CAT1024ZI-30-GT3

Supervisors Overview

The CAT1024ZI-30-GT3 is a voltage supervisory circuit manufactured by onsemi, housed in an MSOP-8 package. It integrates a 2k-bit CMOS EEPROM with I2C serial interface and features manual reset functionality. The device monitors supply voltage with a threshold of 3 V and supports operation between 2.7 V and 5.5 V. It operates within a temperature range of -40°C to +85°C, consumes 3 mA working current, and includes a 200 ms reset delay time.

Supervisors Feature Summary

• Integrates 2k-bit CMOS EEPROM with I2C serial communication
• Provides manual reset capability for system control
• Monitors single input voltage with defined thresholds

Supervisors Applications

• CPU supervision in embedded systems
• Voltage monitoring for microcontroller units
• Data storage protection in portable electronics

Supervisors Procurement Notes

Verify the specific suffix GT3 indicates tape and reel packaging configuration when sourcing. Confirm RoHS compliance status through official documentation prior to integration. Ensure the MSOP-8 footprint matches the target PCB design constraints. Cross-reference the manufacturer part number against authorized distributor catalogs to validate authenticity and current production status.

Supervisors Selection Notes

Select this component when both voltage supervision and non-volatile data storage are required in a compact form factor. The integrated I2C interface simplifies connectivity compared to separate memory and supervisor chips. Consider the 3 V threshold and 2.7 V minimum operating voltage to ensure compatibility with the target system power rails and logic levels.

Supervisors Part Context

This part belongs to the CAT1024 series of supervisory circuits from onsemi. The series combines power management IC functions with serial EEPROM capabilities. The ZI suffix typically denotes the MSOP-8 package variant, while the 30 indicates the 3 V threshold voltage setting within the product family.

Supervisors Replacement Considerations

CAT1024WI-30-T3 offers similar functionality but uses a SOIC-8 package instead of MSOP-8. CAT1024ZI-45 provides a 4.5 V threshold option within the same package style. Verify pinout compatibility and electrical specifications before substituting any alternative part numbers.
