CAT1320WI-25-TE13

Supervisors Overview

The CAT1320WI-25-TE13 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 industrial operating temperatures from -40°C to +85°C. The component integrates 32K EEPROM memory and draws a typical operating current of 3 mA.

Supervisors Feature Summary

• Integrates 32K EEPROM memory for data storage alongside voltage supervision
• Provides manual reset capability for system control
• Supports single-input voltage monitoring with defined threshold levels

Supervisors Applications

• CPU power supply monitoring
• Embedded systems requiring integrated memory and supervision
• Industrial control units operating in extended temperature ranges

Supervisors Procurement Notes

Verify the specific suffix TE13 against official onsemi documentation to confirm tape-and-reel packaging and lead-free compliance. Confirm end-of-life status through authorized distributors or direct manufacturer channels prior to design finalization. Ensure the SOIC-8 footprint matches your PCB layout requirements. Cross-reference the 2.5 V threshold specifications with your system's voltage rails to guarantee proper operation under all load conditions.

Supervisors Selection Notes

Select this component when a combined voltage supervisor and non-volatile memory solution is required for CPU systems. The fixed 2.5 V threshold suits applications powered by standard 3.3 V or 5 V logic rails. Consider the SOIC-8 package size constraints and the absence of a watchdog timer if automated timeout resets are necessary. Verify that the 3 mA quiescent current aligns with your power budget requirements.

Supervisors Part Context

This part belongs to the CAT1320 series of supervisory circuits from onsemi, which combines power management functions with embedded EEPROM. The series targets applications needing reliable system reset generation and data retention in compact packages. The WI-25 designation indicates specific threshold voltages and package variations within this family.

Supervisors Replacement Considerations

Check for CAT1320YI-25-GT3 as a potential alternative, noting the TSSOP-8 package difference. Verify functional equivalence regarding the 32K EEPROM integration and manual reset feature. Confirm that the operating temperature range and supply voltage limits remain compatible with your design specifications.
