CAT1025WI-30-G

Supervisors Overview

The CAT1025WI-30-G is a supervisory circuit manufactured by onsemi, integrating a 2k-bit serial CMOS EEPROM with a CPU supervisor. It operates within a supply voltage range of 2.7 V to 5.5 V and features a reset threshold voltage of 3 V. The device includes manual reset capability and utilizes an I²C bus interface for memory access. Packaged in an SOIC-Wide-8 format, it supports surface mount installation and functions across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates system power supervision with brown-out protection and 2k-bit serial EEPROM memory
• Provides dual open-drain outputs for active high and active low reset signaling
• Includes write protect input to disable memory operations when connected to logic high

Supervisors Applications

• Microcontroller-based systems requiring integrated memory and supervision
• Portable electronics needing low-power voltage monitoring
• Industrial control units utilizing I²C communication interfaces

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for End-of-Life notices or production discontinuation updates. Ensure the specific package variant matches design requirements before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a combined voltage supervisor and non-volatile storage solution is required. Verify that the 3 V threshold aligns with the target system's minimum operating voltage. Ensure the I²C interface compatibility exists with the primary microcontroller or processor in the design architecture.

Supervisors Part Context

This part belongs to the CAT1025 series of supervisory circuits from onsemi. These devices are designed to provide complete memory and supervisory solutions for embedded systems. The series combines low-power CMOS technology with reliable I²C serial interfaces for data retention and system stability.

Supervisors Replacement Considerations

Check for CAT1025ZI-30-G as a potential alternative with TSSOP-8 packaging. Verify functional equivalence regarding threshold voltages and EEPROM capacity before substitution.
