CAT1163WI-30

Supervisors Overview

The CAT1163WI-30 is a supervisory circuit manufactured by onsemi, designed for CPU monitoring applications. It integrates a 16K EEPROM memory array with voltage supervision capabilities. The device operates within a supply voltage range of 2.7 V to 6 V and features a threshold voltage of 3 V. Key electrical parameters include an overvoltage threshold of 3.15 V, a reset delay time of 270 ms, and a maximum power dissipation of 1 W. The component supports manual reset functionality and includes a watchdog timer. It is available in an 8-SOIC package and operates across temperature ranges from -40°C to +85°C or -55°C to +125°C depending on the specific variant.

Supervisors Procurement Notes

Verify obsolescence status as multiple sources indicate this part may be discontinued. Confirm RoHS compliance details through official datasheets, as some listings show conflicting information. Ensure the specific suffix matches required packaging and temperature grades. Cross-reference manufacturer part numbers with distributor codes to avoid ordering errors due to legacy naming conventions.

Supervisors Selection Notes

Select this component when both voltage supervision and non-volatile data storage are required in a single package. Compare threshold voltages and reset delays against system requirements. Verify operating temperature range compatibility with the application environment. Consider alternative parts if the integrated EEPROM is not needed to reduce complexity.
