CAT1641YI-42-G

Supervisors Overview

The CAT1641YI-42-G is a voltage supervisory circuit manufactured by onsemi, designed for CPU monitoring applications. It operates within a supply voltage range of 3 V to 5.5 V and features an undervoltage threshold between 4.25 V and 4.5 V. The device provides manual reset functionality with a reset delay time of 5 µs. It utilizes an open collector/drain output type and consumes a working supply current of 1 mA or 3 mA. Packaged in TSSOP-8, it supports surface mount installation and functions across temperatures from -40°C to +85°C.

Supervisors Feature Summary

• Integrates manual reset capability for system control
• Provides undervoltage supervision with fast reset delay
• Supports single input monitoring configuration

Supervisors Applications

• CPU power supply monitoring
• Embedded system reset generation
• Voltage supervision in industrial equipment

Supervisors Procurement Notes

Verify component authenticity through authorized distributors. Confirm RoHS compliance status via official documentation. Check manufacturing date codes for lot traceability. Ensure storage conditions meet semiconductor handling standards. Validate package integrity against shipping damage risks.

Supervisors Selection Notes

Select this component when precise undervoltage detection near 4.5 V is required. Consider the 5 µs reset delay for timing-sensitive designs. Verify compatibility with TSSOP-8 footprint constraints. Evaluate power consumption requirements against the 1 mA or 3 mA operating current options.

Supervisors Part Context

Part of the CAT1641 series focusing on voltage supervision. Shares family characteristics with other CAT1641 variants but differs in package type and specific threshold settings. Designed as a standalone supervisory solution without integrated EEPROM memory found in some sibling models.

Supervisors Replacement Considerations

CAT1641YI-42-GT3 offers identical electrical specifications in tape-and-reel packaging.
