CAT1025WI-25-G

Supervisors Overview

The CAT1025WI-25-G is a voltage supervisory circuit manufactured by onsemi, designed for CPU monitoring applications. It integrates a 2Kb EEPROM with the supervisor function in an SOIC-8 surface-mount package. The device features a threshold voltage of 2.5 V and supports manual reset input. It operates within a supply voltage range of 2.7 V to 5.5 V and functions across a temperature range of -40°C to +85°C. The component draws 3 mA of operating current and has a power dissipation rating of 1 W. It provides active high, active low, and open drain output types without a watchdog timer.

Supervisors Feature Summary

• Integrates CPU supervision with non-volatile memory storage
• Supports multiple output configurations including active high, active low, and open drain
• Includes manual reset capability for system control

Supervisors Applications

• CPU voltage monitoring in embedded systems
• Power supply support circuits requiring manual reset
• Data retention applications using integrated EEPROM

Supervisors Procurement Notes

Verify end-of-life status and obsolescence notices before design finalization. Confirm RoHS compliance details through official datasheets. Check regional distribution restrictions as availability may vary. Validate package dimensions against PCB footprint requirements. Ensure thermal management aligns with specified power dissipation limits.

Supervisors Selection Notes

Select this component when a combined supervisor and EEPROM solution is required in an SOIC-8 package. Verify that the 2.5 V threshold matches the target system voltage. Consider the manual reset requirement versus automatic reset needs. Evaluate the 3 mA current consumption against power budget constraints. Confirm compatibility with I2C interface if memory access is needed.

Supervisors Part Context

This part belongs to the CAT1025 series of supervisory circuits from onsemi. The series offers various threshold voltages and package options. The WI suffix indicates a wide-body SOIC package variant. The 25 designation specifies the 2.5 V threshold voltage. The G suffix typically denotes lead-free and halogen-free compliance.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the CAT1025 family with different thresholds. Verify functional equivalence with other supervisors offering integrated EEPROM. Compare package dimensions for mechanical fit. Ensure electrical parameters match system requirements.
