CAT1027WI-42-GT3

Supervisors Overview

The CAT1027WI-42-GT3 is a voltage supervisory circuit manufactured by onsemi, designed for CPU supervision with an integrated 2K EEPROM. It operates within a supply voltage range of -2 V to 7 V and features a reset delay time of 5 us. The device monitors two inputs and provides an open collector/drain output type. It includes manual reset capability and a watchdog timer function. The component is housed in an SOIC-Wide-8 package suitable for surface mount installation. It functions within a temperature range of -40 C to +85 C and consumes 10 uA of operating power.

Supervisors Feature Summary

• Integrates 2K EEPROM for data storage alongside voltage supervision
• Includes manual reset input and watchdog timer functionality
• Supports dual input monitoring with open collector/drain outputs

Supervisors Applications

• CPU system supervision
