CAT1320WI-30-GT3

Supervisors Overview

The CAT1320WI-30-GT3 is a supervisory circuit manufactured by onsemi, designed for CPU monitoring applications. It integrates a 32K CMOS EEPROM with I2C serial interface capabilities. The device monitors a single voltage input with a threshold of 3V. It operates within a supply voltage range of 3V to 5.5V and features an open drain or open collector output. The component supports manual reset functionality and includes a watchdog timer. It is housed in an 8-SOIC package and operates across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates 32K CMOS EEPROM with I2C serial interface for data storage alongside supervision
• Provides CPU monitoring with configurable reset thresholds and manual reset capability
• Includes built-in watchdog timer for system reliability enhancement

Supervisors Applications

• CPU power supply monitoring in embedded systems
• Data logging applications utilizing integrated EEPROM
• Industrial control systems requiring voltage supervision

Supervisors Procurement Notes

Verify the specific suffix GT3 indicates tape and reel packaging when ordering. Confirm the 30 designation corresponds to the 3V threshold variant. Ensure compatibility with I2C bus requirements for the integrated memory section. Check current availability status as distribution may vary by region.

Supervisors Selection Notes

Select this component when both voltage supervision and non-volatile data storage are required in a single package. The I2C interface allows for flexible configuration of reset parameters. Consider the SOIC-8 footprint for PCB layout constraints. Verify that the 3V threshold aligns with the target supply rail being monitored.

Supervisors Part Context

This part belongs to the CAT1320 series of supervisory circuits from onsemi. The series combines power management functions with memory capabilities. The WI suffix typically denotes wide-body or specific package variations within the family. The GT3 suffix specifies the reel packaging format for automated assembly processes.

Supervisors Replacement Considerations

CAT1320WI-42-G offers similar supervision but with a different threshold voltage. CAT1022WI-30-GT3 provides comparable functionality but with only 2K EEPROM capacity. Verify pinout compatibility and I2C address settings when substituting.
