CAT1320LI-45-G

Supervisors Overview

The CAT1320LI-45-G is a voltage supervisory circuit manufactured by onsemi, designed for CPU monitoring applications. It features a single monitored input with a threshold voltage of 4.5 V and an overvoltage threshold of 4.75 V. The device supports manual reset functionality and lacks a watchdog timer or battery backup switch. It operates within a supply voltage range of 2.7 V to 6 V and includes a reset delay time of 270 ms. The component is available in an 8-PDIP through-hole package and functions reliably across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides voltage supervision for single-input systems with manual reset capability
• Features open drain output configuration for flexible interface integration
• Operates within a wide supply voltage range suitable for standard logic levels

Supervisors Applications

Supervisors Procurement Notes

Verify current availability status as the component may be discontinued or subject to limited distribution channels. Confirm package type and pinout compatibility during integration planning. Check for alternative sources if original manufacturer stock is unavailable. Ensure environmental compliance documentation matches project requirements before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when a simple voltage supervisor with manual reset is required for single-channel monitoring. Consider the 8-PDIP package for through-hole assembly needs. Evaluate the 270 ms reset delay against system startup timing requirements. Verify that the absence of a watchdog timer aligns with the application's fault management strategy.

Supervisors Part Context

This part belongs to the category of voltage supervisory circuits used for monitoring power rails in electronic systems.
