CAT1022ZI-25-GT3

Supervisors Overview

The CAT1022ZI-25-GT3 is a voltage supervisory circuit manufactured by onsemi, designed for CPU supervision with integrated 2K EEPROM. It operates within a supply voltage range of 2.7 V to 5.5 V and features a manual reset input. The device provides an open collector/drain output with a reset delay time of 5 µs. It supports undervoltage thresholds between 2.55 V and 2.7 V while consuming only 10 µA of operating current. Packaged in an MSOP-8 surface-mount format, it functions reliably across temperatures from -40°C to +85°C.

Supervisors Feature Summary

• Integrates nonvolatile memory for data storage alongside voltage monitoring capabilities
• Provides manual reset functionality for system control flexibility
• Features low power consumption suitable for battery-operated applications

Supervisors Applications

• CPU supervision in embedded systems
• Data retention in portable electronic devices
• Industrial control system monitoring

Supervisors Procurement Notes

Verify component authenticity through authorized distributors as the part status is listed as obsolete. Confirm package integrity and pin alignment against the MSOP-8 specification sheet before integration. Ensure design compatibility with existing voltage rails given the specific threshold requirements. Check for alternative sourcing options due to potential supply chain limitations associated with discontinued components.

Supervisors Selection Notes

Select this component when combined voltage supervision and small-scale data storage are required in a compact footprint. The MSOP-8 package suits space-constrained designs compared to larger DIP alternatives. Consider the manual reset feature if external push-button intervention is necessary for system recovery. Evaluate the low quiescent current benefit for power-sensitive applications requiring extended operational life without frequent maintenance.

Supervisors Part Context

This component belongs to the CAT1022 series of supervisory circuits produced by onsemi. The series focuses on providing reliable power management solutions for microprocessor systems. The ZI suffix indicates the MSOP-8 package variant, distinguishing it from other package options like TSSOP. This specific model integrates EEPROM functionality, differentiating it from basic voltage monitors that lack data storage capabilities.
