CAT1320WI-25-GT3

Supervisors Overview

The CAT1320WI-25-GT3 is a voltage supervisory circuit manufactured by onsemi, designed for CPU monitoring applications. It features a single monitored input with a threshold voltage of 2.5 V and an overvoltage threshold of 2.7 V. The device operates within a supply voltage range of 3 V to 5.5 V and consumes 3 mA of working power current. It provides manual reset functionality without a watchdog timer. The component is housed in an SOIC-8 package and supports surface mount installation. It functions reliably across a temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates voltage supervision with manual reset capability for system protection
• Monitors a single input line with defined under-voltage and over-voltage thresholds
• Supports surface mount technology in an SOIC-8 package

Supervisors Applications

• CPU power supply monitoring
• Voltage supervision in embedded systems
• Manual reset control circuits

Supervisors Procurement Notes

Verify the specific suffix GT3 against official documentation to confirm packaging details. Confirm RoHS compliance status through manufacturer datasheets. Check for end-of-life notifications or discontinuance alerts prior to procurement. Ensure the SOIC-8 package variant matches design requirements. Validate operating temperature ranges for the intended application environment.

Supervisors Selection Notes

Select this component when a single-input voltage supervisor with manual reset is required. Ensure the 2.5 V threshold aligns with the monitored rail voltage. Verify that the 3 mA quiescent current fits the power budget. Confirm compatibility with the SOIC-8 footprint. Consider the absence of a watchdog timer if timing protection is needed.
