CAT1320WI-25

Supervisors Overview

The CAT1320WI-25 is a voltage supervisory circuit manufactured by onsemi, designed for CPU monitoring applications. It operates within a supply voltage range of 3 V to 5.5 V and features a threshold voltage of 2.5 V. The device includes manual reset functionality and lacks a watchdog timer. It is housed in an SOIC-8 surface-mount package and supports operation temperatures from -40°C to +85°C. Key electrical parameters include a maximum power dissipation of 1 W and a quiescent current of 3 mA.

Supervisors Feature Summary

• Provides voltage supervision with manual reset capability for system stability
• Supports surface-mount installation in compact SOIC-8 packages
• Operates reliably across extended industrial temperature ranges

Supervisors Applications

• CPU power supply monitoring
• Voltage supervision in embedded systems
• Industrial control unit reset circuits

Supervisors Procurement Notes

Verify component authenticity through authorized channels as the part may be end-of-life. Confirm RoHS compliance status via official manufacturer documentation before integration. Ensure packaging specifications match design requirements for SMD/SMT assembly processes.

Supervisors Selection Notes

Select this component when a dedicated voltage supervisor with manual reset is required. Verify that the 2.5 V threshold aligns with target rail voltages. Consider package availability and thermal management needs given the 1 W power dissipation rating.

Supervisors Part Context

Part of the CAT1320 series of supervisory circuits from onsemi. This family focuses on reliable voltage monitoring for microprocessor and memory systems. The WI suffix indicates specific package and temperature grade variations within the broader product line.

Supervisors Replacement Considerations

Check for direct pin-compatible substitutes within the CAT1320 family or similar onsemi supervisors. Verify functional equivalence regarding threshold voltage and reset behavior before substitution.
