CAT1024LI-28

Supervisors Overview

The CAT1024LI-28 is a voltage supervisory circuit manufactured by onsemi, designed for monitoring single-channel power supply voltages. It operates within a supply voltage range of 2.7 V to 5.5 V and features a threshold voltage of 2.8 V. The device includes manual reset functionality and provides an open collector/drain output type. It is housed in an 8-pin PDIP package suitable for through-hole mounting. The component supports an industrial temperature range from -40°C to +85°C and consumes a typical operating supply current of 3 mA.

Supervisors Feature Summary

• Integrates voltage supervision with manual reset capability for reliable system control
• Provides open collector or open drain output interface for flexible logic compatibility
• Supports through-hole installation via standard 8-pin DIP packaging

Supervisors Applications

• Microprocessor system power monitoring
• Portable equipment voltage supervision
• Industrial control board reset circuits

Supervisors Procurement Notes

Verify the specific suffix designation when ordering, as variations may indicate different packaging or temperature grades. Confirm end-of-life status with the manufacturer prior to final design approval. Ensure the selected variant matches the required through-hole mounting style and industrial temperature specifications for your application environment.

Supervisors Selection Notes

Select this component when a single-channel supervisor with manual reset is required for through-hole designs. Compare against surface-mount alternatives if space constraints exist. Verify that the 2.8 V threshold aligns with the monitored rail's minimum operating voltage. Consider the 3 mA quiescent current impact on total system power budget during selection.

Supervisors Part Context

This part belongs to the CAT1024 series of supervisory circuits from onsemi. The series typically combines voltage monitoring with non-volatile memory functions in some variants, though this specific model focuses on supervision. It serves as a critical component for ensuring system stability during power-up and power-down sequences in electronic devices requiring robust voltage oversight.

Supervisors Replacement Considerations

Check for CAT1024LI-28-G as a potential alternative with RoHS compliance confirmation. Evaluate CAT1024SE-28-TE13 for surface-mount requirements, noting the package change from PDIP to SOIC. Verify functional equivalence regarding threshold voltage and reset delay before substitution.
