CAT1025YI-30

Supervisors Overview

The CAT1025YI-30 is a voltage supervisory circuit manufactured by onsemi, designed for CPU supervision with integrated 2K-bit EEPROM. It operates within a supply voltage range of 2.7 V to 5.5 V and features a threshold voltage of 3 V. The device supports manual reset functionality and includes an open collector/drain output type. It is housed in a TSSOP-8 package suitable for surface mount installation. The component functions across a temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates system power supervisor with brown-out protection and 2k-bit serial EEPROM memory
• Provides precision voltage sense circuitry with dedicated reset outputs
• Supports I2C bus interface for memory access and configuration

Supervisors Applications

• Microcontroller-based systems requiring power monitoring
• Embedded devices needing non-volatile data storage alongside supervision
• Industrial control units operating in wide temperature environments

Supervisors Procurement Notes

Verify current availability status as the component may be discontinued or subject to limited supply. Confirm RoHS compliance details and specific ordering suffixes required for your region. Check manufacturer documentation for end-of-life notifications and recommended replacement strategies before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a combined solution for voltage supervision and small-scale data retention is required. Ensure the 3V threshold aligns with your system's minimum operating voltage. Verify that the TSSOP-8 package fits your PCB layout constraints and that the I2C interface matches your microcontroller capabilities.
