CAT1641YI-45-GT3

Supervisors Overview

The CAT1641YI-45-GT3 is a voltage supervisory circuit manufactured by onsemi, designed for CPU supervision applications. It features an integrated 64K EEPROM and operates within a supply voltage range of 3 V to 5.5 V. The device monitors a single input with a threshold voltage between 4.25 V and 4.5 V. It provides an open collector/drain output type and includes manual reset functionality without a watchdog timer. The reset delay time is specified at 5 us. Operating temperatures range from -40 C to +85 C, and it is housed in a TSSOP-8 package.

Supervisors Feature Summary

• Integrates 64K EEPROM for non-volatile data storage alongside voltage supervision
• Provides manual reset capability with fast 5 us reset delay
• Features open collector/drain output for flexible interface compatibility

Supervisors Applications

• CPU power supply monitoring systems
• Embedded controller reset circuits
• Industrial control board supervision

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential counterfeit risks. Confirm RoHS compliance status via official datasheets before integration. Check current lifecycle status as availability may vary. Ensure packaging specifications match assembly requirements. Validate electrical parameters against specific application needs prior to procurement.

Supervisors Selection Notes

Select this component when 64K EEPROM capacity is required alongside voltage supervision. Consider the 5 us reset delay for timing-sensitive applications. Verify that the TSSOP-8 package fits the PCB layout constraints. Ensure the operating temperature range meets environmental conditions. Compare against other CAT1641 variants if different EEPROM sizes or thresholds are needed.

Supervisors Part Context

Part of the CAT1641 series from onsemi, focusing on combined supervision and memory solutions. Designed for industrial and commercial electronics requiring reliable power management. Competes with similar supervisor ICs offering integrated storage capabilities.

Supervisors Replacement Considerations

Check for CAT1641 family members with different EEPROM sizes or threshold voltages. Verify pinout compatibility with existing designs. Confirm package dimensions match current footprint.
