CAT1026ZI-28-GT3

Supervisors Overview

The CAT1026ZI-28-GT3 is a voltage supervisory circuit manufactured by onsemi, designed for monitoring power supply integrity in electronic systems. It features an 8-MSOP surface-mount package and supports a maximum operating voltage of 5.5 V with a minimum input of 2.7 V. The device monitors two independent channels, providing open-drain outputs for under-voltage detection. It operates within a temperature range of -40°C to +85°C and consumes low quiescent current, making it suitable for battery-powered applications requiring reliable reset signaling without manual intervention or watchdog functionality.

Supervisors Feature Summary

• Dual-channel voltage supervision for comprehensive power monitoring
• Open-drain output configuration for flexible logic interfacing
• Compact 8-lead MSOP package for space-constrained designs

Supervisors Applications

• Portable consumer electronics requiring dual rail monitoring
• Industrial control systems needing reliable power supervision
• Battery-operated devices with strict power management requirements

Supervisors Procurement Notes

Verify the specific suffix GT3 indicates tape and reel packaging when ordering. Confirm the manufacturer part number matches exactly to ensure correct voltage thresholds and package type. Check for RoHS compliance documentation if required for your region. Ensure the supplier is an authorized distributor to guarantee component authenticity and traceability.

Supervisors Selection Notes

Select this component when dual-channel supervision is necessary within a small footprint. Compare against single-channel supervisors if only one rail requires monitoring. Consider the open-drain output requirement for pull-up resistor integration. Verify that the 2.7 V to 5.5 V operating range aligns with your system's power rails.

Supervisors Part Context

This part belongs to the CAT1026 series of supervisory circuits from onsemi. It complements other variants like the CAT1026UI-28-TE13 which offers different packaging options such as TSSOP-8. The series provides essential power management functions for modern embedded systems, ensuring stable operation through continuous voltage monitoring.

Supervisors Replacement Considerations

The CAT1026UI-28-TE13 serves as a functional alternative with similar voltage specifications but utilizes a TSSOP-8 package instead of MSOP-8. Verify pin compatibility and package dimensions before substitution. Other CAT1026 variants may offer different channel counts or reset features.
