CAT1024ZD4I-28-T2-A2

Supervisors Overview

The CAT1024ZD4I-28-T2-A2 is a supervisory circuit integrating a 2k-bit serial EEPROM and a voltage monitor. It operates within a supply voltage range of 2.7 V to 5.5 V with a threshold of 2.8 V. The device features an I²C bus interface, manual reset input, and open-drain outputs. It supports industrial temperature ranges from -40°C to +85°C and utilizes low-power CMOS technology for brown-out protection.

Supervisors Feature Summary

• Integrates 2k-bit serial EEPROM memory with system power supervisor
• Provides precision voltage monitoring with manual reset capability
• Supports standard I²C bus communication interface
• Includes built-in inadvertent write protection mechanisms

Supervisors Applications

• Microcontroller-based system power management
• Brown-out protection for embedded controllers
• Data retention in portable electronic devices
• System supervision in industrial control units

Supervisors Procurement Notes

Verify the specific suffix codes against official datasheets to confirm package type and temperature grade. Confirm end-of-life status as distribution availability varies. Ensure compatibility with existing I²C addressing configurations before integration into new designs.

Supervisors Selection Notes

Select this component when combined memory and supervision are required in a single package. Verify that the 2.8 V threshold aligns with the target system voltage rails. Consider the TSSOP-8 or similar small outline packages if board space is limited compared to larger DIP alternatives.

Supervisors Part Context

This part belongs to the CAT1024/CAT1025 family of supervisory circuits with integrated EEPROM. These devices combine non-volatile storage with power management functions. The CAT1024 variant specifically lacks the write protect pin found in the CAT1025 model, offering a simplified interface for applications where external write protection is unnecessary.
