CAT1027WI-30-GT3

Supervisors Overview

The CAT1027WI-30-GT3 is a multi-voltage supervisory circuit manufactured by onsemi, designed for CPU supervision with integrated 2K EEPROM. It operates within a supply voltage range of 2.7 V to 5.5 V and features a reset threshold of 3 V to 3.15 V. The device includes a watchdog timer, manual reset capability, and an open-drain output type. It is housed in an SOIC-8 package and supports industrial temperature ranges from -40°C to +85°C.

Supervisors Feature Summary

• Integrates CPU supervision with non-volatile memory storage
• Includes built-in watchdog timer functionality
• Supports manual reset input for system control

Supervisors Applications

• CPU power monitoring in embedded systems
• Industrial control unit supervision
• Consumer electronics power management

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for end-of-life notices, as availability may be limited. Ensure the specific suffix matches required packaging and temperature grades before ordering.

Supervisors Selection Notes

Select this component when combined voltage supervision and data retention are required in a single package. Compare against similar CAT1027 variants for different voltage thresholds or package types. Verify that the open-drain output configuration aligns with the target microcontroller's reset input requirements.

Supervisors Part Context

This part belongs to the CAT1027 series of supervisory circuits, which combine voltage monitoring with EEPROM capabilities. It serves as a compact solution for systems needing both power integrity checks and persistent data storage without requiring separate components.

Supervisors Replacement Considerations

Check for CAT1027WI-25-GT3 or CAT1027ZI-42-T3 if different voltage thresholds or packages are needed. Verify pin compatibility and electrical specifications before substituting.
