CAT1641YI-25-GT3

Supervisors Overview

The CAT1641YI-25-GT3 is a voltage supervisory circuit manufactured by onsemi, designed for CPU supervision applications. It integrates a 64Kb EEPROM within the supervisory logic. The device operates with a supply voltage range from 3 V to 5.5 V and features an undervoltage threshold between 4.25 V and 4.5 V. It provides a manual reset input and delivers an open collector/drain output. The reset delay time is specified at 5 µs. The component supports a maximum power dissipation of 1 W and functions within an operating temperature range of -40°C to +85°C. It is housed in a TSSOP-8 surface-mount package.

Supervisors Feature Summary

• Integrates non-volatile 64Kb EEPROM storage directly within the supervisory circuit architecture
• Provides precise voltage monitoring with a dedicated manual reset input capability
• Features fast response characteristics with a 5 µs reset delay time

Supervisors Applications

• CPU voltage supervision systems
• Embedded controller power management
• Industrial control board monitoring

Supervisors Procurement Notes

Verify current production status as availability may vary. Confirm RoHS compliance details through official documentation. Ensure the TSSOP-8 package matches your PCB footprint requirements. Validate the specific voltage threshold specifications against your system design needs before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when integrated memory and supervision are required in a single package. The 64Kb EEPROM allows for data retention alongside system monitoring. The 5 µs reset delay suits applications requiring rapid recovery. Ensure the 3 V to 5.5 V operating range aligns with your system's power rails and that the TSSOP-8 package fits your layout constraints.

Supervisors Part Context

This part belongs to the CAT1641 series of supervisory circuits from onsemi. These devices combine voltage monitoring with embedded EEPROM capabilities. The series targets applications needing both system reliability monitoring and persistent data storage in compact packages. The CAT1641 family offers various threshold options to suit different voltage rail requirements.

Supervisors Replacement Considerations

Check for CAT1641 variants with different voltage thresholds or EEPROM sizes. Verify pin compatibility with existing TSSOP-8 footprints. Confirm functional equivalence regarding reset delay and output type.
