CAT1027ZI-30-GT3

Supervisors Overview

The CAT1027ZI-30-GT3 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 5.5 V and features a threshold voltage of 3 V with an overvoltage threshold of 3.15 V. The device includes a watchdog timer and provides active high, active low, and open drain outputs. It supports manual reset functionality and has a reset delay time of 200 ms. The component is housed in an MSOP-8 package and operates across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Provides multiple output configurations including active high, active low, and open drain
• Supports manual reset input for user-initiated system recovery

Supervisors Applications

• CPU power supply monitoring
• Embedded system supervision
• Industrial control unit protection

Supervisors Procurement Notes

Verify the exact suffix GT3 against official datasheets to confirm package and tape/reel specifications. Confirm current lifecycle status as obsolescence may impact long-term availability. Cross-reference pinout diagrams for MSOP-8 compatibility during integration planning.

Supervisors Selection Notes

Select this component when a 3V threshold is required for single-input voltage supervision. Ensure design requirements align with the 200ms reset delay and available output types. Verify thermal performance within the specified operating temperature range for the target application environment.

Supervisors Part Context

This part belongs to the CAT1027 series of supervisory circuits from onsemi. It shares functional similarities with other parts in the family but differs in package type and specific electrical parameters. The ZI suffix typically indicates the MSOP-8 package variant.

Supervisors Replacement Considerations

Check for direct substitutes within the CAT1027 series or compatible voltage supervisors from onsemi. Verify pin-to-pin compatibility and matching threshold voltages before substitution.
