CAT1025WI-28-GT3

Supervisors Overview

The CAT1025WI-28-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 2.8 V. The device monitors one input and includes manual reset functionality without a watchdog timer. It is housed in an SOIC-8 surface-mount package and supports industrial temperature ranges from -40°C to +85°C. The component draws 3 mA of operating current and dissipates up to 1 W of power.

Supervisors Feature Summary

• Provides voltage supervision with manual reset capability for system stability
• Supports single-input monitoring with defined threshold detection
• Operates reliably across extended industrial temperature conditions

Supervisors Applications

• CPU power supply monitoring
• Voltage supervision in embedded systems
• Industrial control unit reset management

Supervisors Procurement Notes

Verify the specific suffix GT3 against official datasheets to confirm tape-and-reel packaging and RoHS compliance status. Confirm end-of-life or obsolescence status directly with onsemi, as distribution listings may vary. Ensure the SOIC-8 footprint matches your PCB design constraints before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when a simple voltage supervisor with manual reset is required for CPU monitoring. It is suitable for designs needing a 2.8 V threshold within a 2.7 V to 5.5 V supply range. Consider the SOIC-8 package size and 3 mA current consumption relative to other supervisory options in the CAT1025 series.

Supervisors Part Context

This part belongs to the CAT1025 series of voltage supervisors from onsemi. These devices are engineered for reliable power management in digital circuits. The series typically offers various threshold voltages and package options to suit different system requirements while maintaining consistent performance characteristics.

Supervisors Replacement Considerations

Check for CAT1025WI-28-T3 for reel packaging variations. Verify CAT1025WI-28-G for tube packaging alternatives. Ensure any substitute maintains the 2.8 V threshold and SOIC-8 form factor.
