CAT1163WI-25-T3

Supervisors Overview

The CAT1163WI-25-T3 is a voltage supervisory circuit manufactured by onsemi, designed for CPU monitoring applications. It operates within a supply voltage range of 2.7 V to 6 V and features a threshold voltage of 2.5 V with an overvoltage threshold of 2.7 V. The device includes a manual reset input, a watchdog timer, and offers active high, active low, or open drain output types. It incorporates 16 Kbit EEPROM for data storage and maintains a reset delay time of 270 ms. Operating temperatures span from -40 °C to +85 °C, housed in an SOIC-Wide-8 package.

Supervisors Feature Summary

• Integrates 16 Kbit EEPROM for non-volatile data retention alongside voltage supervision capabilities.
• Includes a built-in watchdog timer to ensure system reliability and fault recovery.
• Provides flexible output configurations including active high, active low, and open drain options.
