CAT1163WI30

Supervisors Overview

The CAT1163WI-30 is a voltage supervisory circuit manufactured by onsemi, designed for CPU monitoring applications. It integrates a 16K EEPROM with the supervisor functionality. The device operates within a supply voltage range of 2.7 V to 6 V and features a threshold voltage of 3 V with an overvoltage threshold of 3.15 V. It includes a manual reset input and a watchdog timer. The reset delay time is specified at 270 ms. The component supports active high, active low, and open drain outputs. It is housed in an 8-pin SOIC-Wide package and operates between -40°C and +85°C.

Supervisors Feature Summary

• Integrates 16K EEPROM for data storage alongside supervisory functions
• Includes built-in watchdog timer for system reliability
• Supports multiple output configurations including open drain

Supervisors Applications

• CPU power supply monitoring
• Embedded system reset control
• Data retention management via integrated EEPROM

Supervisors Procurement Notes

Verify current availability status as this part may be discontinued or subject to limited supply. Confirm RoHS compliance details through official datasheets. Ensure the specific suffix matches required packaging options such as reel or cut tape. Cross-reference ordering numbers with authorized distributors to avoid counterfeit components.

Supervisors Selection Notes

Select this component when both voltage supervision and non-volatile memory are required in a single package. Compare against CAT1162 variants if watchdog functionality is not needed. Verify that the 3V threshold aligns with the target system's logic levels. Check operating temperature range requirements against application conditions.

Supervisors Part Context

This part belongs to the CAT1163 series of supervisory circuits from onsemi. It shares similarities with the CAT1162 but adds a watchdog timer feature. The CAT1163 family provides integrated solutions for microprocessor systems requiring both reset generation and data storage capabilities in compact surface-mount packages.

Supervisors Replacement Considerations

CAT1162WI-30-GT3 serves as a substitute lacking the watchdog timer. CAT1163WI-45-GT3 offers a higher 4.5V threshold version. Verify pin compatibility and functional differences before substitution.
