CAT1025WI-30-GT3

Supervisors Overview

The CAT1025WI-30-GT3 is a voltage supervisory circuit manufactured by onsemi, featuring an integrated 2-kbit CMOS EEPROM with I2C serial interface. It operates within a supply voltage range of 2.7 V to 5.5 V and monitors a single input line. The device provides manual reset functionality and utilizes an SOIC-Wide-8 surface-mount package. Key electrical parameters include a threshold voltage of 3 V, an overvoltage threshold of 3.15 V, and a quiescent current of 3 mA. It supports operation across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a 2-kbit CMOS EEPROM accessible via the I2C serial communication protocol for non-volatile data storage.
• Provides hardware-based voltage supervision with manual reset capability to ensure system stability during power fluctuations.
• Supports flexible output configurations including active high, active low, and open drain options.

Supervisors Applications

• CPU supervisor circuits in embedded systems requiring reliable power monitoring.
• Data logging applications utilizing the integrated EEPROM for storing calibration or configuration data.
• Industrial control systems operating within standard voltage rails.

Supervisors Procurement Notes

Verify component authenticity through authorized distributors due to potential counterfeit risks. Confirm RoHS compliance status as indicated in official documentation. Check for end-of-life notices or obsolescence warnings from onsemi before finalizing procurement plans. Ensure packaging specifications match design requirements for surface mount assembly processes.
