CAT1320LI-25-G

Supervisors Overview

The CAT1320LI-25-G is a supervisory circuit manufactured by onsemi, featuring an integrated 32 kbit CMOS EEPROM. It operates within a supply voltage range of 2.7 V to 6 V and includes a manual reset function with a reset delay time of 270 ms. The device monitors one input with an undervoltage threshold of 2.55 V and an overvoltage threshold of 2.7 V. It utilizes an I2C serial interface for data communication and is housed in a PDIP-8 package suitable for through-hole mounting.

Supervisors Feature Summary

• Integrates CPU supervisory functions with non-volatile memory storage
• Provides manual reset capability with defined delay timing
• Supports I2C serial interface for configuration and data access

Supervisors Applications

• CPU power supply monitoring systems
• Embedded systems requiring hardware reset control
• Data logging applications needing onboard EEPROM storage

Supervisors Procurement Notes

Verify component authenticity due to obsolete lifecycle status. Confirm package integrity and pin alignment against datasheet specifications. Check for RoHS compliance documentation. Ensure replacement strategies account for discontinuation risks. Validate electrical parameters against original design requirements before integration.

Supervisors Selection Notes

Select this component when combined supervision and storage are required in a single package. Consider the I2C interface compatibility with the host controller. Evaluate the operating temperature range against environmental conditions. Assess the power dissipation limits relative to thermal constraints. Verify that the reset thresholds align with system voltage tolerances.

Supervisors Part Context

This part belongs to the CAT1320 series of supervisory circuits with embedded EEPROM. It serves as a specialized solution for systems needing both power management oversight and persistent data retention. The PDIP-8 packaging distinguishes it from surface-mount variants in the same family. It complements other onsemi memory and PMIC products by offering integrated functionality.
