CAT1022YI-42-GT3

Supervisors Overview

The CAT1022YI-42-GT3 is a voltage supervisory circuit manufactured by onsemi, designed for monitoring power supply integrity in electronic systems. It operates within a supply voltage range of 2.7 V to 5.5 V and features a threshold voltage of 4.2 V. The device monitors five inputs and provides an open collector/drain output with manual reset capability. It includes a watchdog timer and offers a reset delay time of 200 ms. Operating temperatures span from -40°C to +85°C, with a maximum power dissipation of 1 W and a typical operating current of 3 mA.

Supervisors Feature Summary

• Monitors multiple voltage inputs to ensure system stability
• Integrates a watchdog timer for fault detection
• Supports manual reset functionality for user control

Supervisors Applications

• CPU voltage supervision
• Power management IC monitoring
• Industrial control systems

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to obsolete status. Confirm RoHS compliance and material composition declarations via official datasheets. Cross-reference part numbers carefully as substitutes may vary in electrical characteristics. Validate package dimensions against design constraints before integration.

Supervisors Selection Notes

Select this component when multi-input voltage monitoring with integrated watchdog functionality is required. Ensure the 4.2 V threshold aligns with target supply rails. Consider the TSSOP-8 package for surface mount compatibility. Verify thermal performance meets system requirements given the 1 W power dissipation limit.

Supervisors Part Context

Part of the CAT1022 series focusing on voltage supervision. Designed for applications requiring reliable power monitoring with minimal external components. Manufactured by onsemi under their standard product portfolio.

Supervisors Replacement Considerations

Check onsemi cross-reference tools for compatible alternatives. Verify functional equivalence regarding input count, threshold voltages, and reset timing. Confirm package compatibility if direct pin-to-pin substitution is needed.
