CAT1026WI-25-T3

Supervisors Overview

The CAT1026WI-25-T3 is a voltage supervisory circuit manufactured by onsemi, designed for CPU supervision applications. It integrates a 2K-bit EEPROM for data storage alongside its monitoring functions. The device operates within a supply voltage range of 2.7 V to 5.5 V and features a threshold voltage of 2.5 V. It utilizes an MSOP-8 surface-mount package and supports SMD/SMT installation styles. The component includes active high, active low, open drain, and CMOS output types. It lacks manual reset and watchdog timer capabilities. The operating temperature range spans from -40°C to +85°C, with a typical supply current of 3 mA.

Supervisors Feature Summary

• Integrates non-volatile 2K-bit EEPROM for persistent data storage within the supervisory circuit.
• Provides flexible output configurations including active high, active low, open drain, and CMOS options.
• Operates across a wide industrial temperature range suitable for diverse environmental conditions.

Supervisors Applications

• CPU system supervision in embedded controllers
• Data retention management in portable electronic devices
• Power management circuits requiring voltage monitoring

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific lot traceability requirements before procurement. Check for any end-of-life notices or alternative part recommendations due to potential supply chain changes. Ensure packaging specifications match assembly line requirements.

Supervisors Selection Notes

Select this component when both voltage supervision and small-scale data storage are required in a single package. Consider the MSOP-8 footprint constraints and the specific 2.5 V threshold requirement for the target power rail. Evaluate the need for multiple output logic levels against other family members if different pinouts are preferred.

Supervisors Part Context

This part belongs to the CAT1026 series of supervisory circuits from onsemi. The series combines voltage monitoring with EEPROM functionality, targeting applications where system state or calibration data must be preserved during power fluctuations. It serves as a compact solution for microcontroller-based systems needing reliable power management and non-volatile memory integration.

Supervisors Replacement Considerations

Check for CAT1026WI-25-G or CAT1026PI-25 variants if different packaging or lead-free specifications are needed. Verify electrical compatibility with CAT1025 or CAT1027 series parts if feature sets like manual reset or watchdog timers become necessary for the design.
