CAT1022ZI-42-GT3

Supervisors Overview

The CAT1022ZI-42-GT3 is a voltage supervisory circuit manufactured by onsemi, designed for CPU supervision with integrated 2K EEPROM. It features an MSOP-8 surface-mount package and operates within a supply voltage range of 2.7 V to 5.5 V. The device monitors a single input line with an undervoltage threshold of 4.25 V to 4.5 V. Key functional attributes include manual reset capability, open collector/drain output, and a reset delay time of 5 µs. It supports industrial temperature ranges from -40°C to +85°C and consumes low quiescent current.

Supervisors Feature Summary

• Integrates non-volatile 2K EEPROM for data storage alongside supervisory functions
• Provides manual reset control for system initialization management
• Features open drain output configuration for flexible interfacing

Supervisors Applications

• CPU power supply monitoring in embedded systems
• Data retention applications requiring integrated memory
• Industrial control circuits requiring manual reset capabilities

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Confirm package integrity and pin alignment against the MSOP-8 specification sheet. Review datasheet revisions for any parameter updates prior to integration. Ensure environmental compliance documentation matches project requirements. Validate thermal performance within the specified operating temperature range during final assembly testing.

Supervisors Selection Notes

Select this component when combined voltage supervision and small-scale data storage are required in a compact footprint. Consider the MSOP-8 package for space-constrained PCB layouts. Evaluate the 5 µs reset delay against system timing requirements. Compare against other CAT1022 variants if different thresholds or watchdog features are needed. Verify compatibility with the target microcontroller's reset input specifications.
