CAT1023WI28

Supervisors Overview

The CAT1023WI-28-G is a supervisory circuit and 2k-bit serial EEPROM combination in an SOIC-8 package. It monitors supply voltage with a threshold of 2.8 V, operating between 2.7 V and 5.5 V. Features include a watchdog timer, manual reset, and I²C interface. Operating temperature ranges from -40°C to +85°C.

Supervisors Feature Summary

• Integrates 2k-bit serial EEPROM with power supply monitoring
• Includes built-in watchdog timer for system reliability
• Supports manual reset functionality via dedicated pin

Supervisors Applications

• Microcontroller-based system supervision
• Brown-out protection circuits
• I²C serial memory applications

Supervisors Procurement Notes

Verify the exact suffix (e.g., -G) against official datasheets to confirm RoHS compliance and specific package variations. Confirm current availability status as distribution listings may indicate discontinuation or limited stock. Ensure the selected variant matches the required threshold voltage and package type for your design.

Supervisors Selection Notes

Select this component when both voltage supervision and non-volatile storage are required in a single package. The 2.8 V threshold suits 3.3 V systems. Verify that the SOIC-8 package fits the PCB layout constraints. Consider the CAT1023LI variant if through-hole mounting is necessary instead of surface mount.

Supervisors Part Context

Part of the CAT102x family combining EEPROM and supervisor functions. The 'WI' indicates SOIC-8 surface mount package. The '28' specifies the 2.8 V threshold voltage. The '-G' denotes Green/RoHS compliant packaging. This series targets embedded systems needing compact memory and supervision solutions.

Supervisors Replacement Considerations

CAT1023LI-28-G offers identical electrical specifications but uses a PDIP-8 through-hole package. CAT1023SI-45-TE13 provides similar features with a 4.5 V threshold. Verify pin compatibility and package dimensions before substitution.
