CAT824LTDI-GT3

Supervisors Overview

The CAT824LTDI-GT3 is a system supervisory voltage reset circuit manufactured by onsemi. It monitors a single voltage input with a threshold of 4.63V and provides an active high/active low push-pull output. The device features a minimum reset timeout of 140ms and includes a watchdog timer for system reliability. It operates within a temperature range of -40°C to +85°C and is housed in a TSOT-23-5 package.

Supervisors Feature Summary

• Monitors system voltage and issues a reset signal when the supply drops below the specified threshold.
• Integrates a watchdog timer to detect system malfunctions and trigger a reset if the input signal fails to toggle.
• Provides flexible output configuration with active high or active low options using a push-pull interface.

Supervisors Applications

• Embedded systems requiring voltage supervision
• Microcontroller reset circuits
• Industrial control systems

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to obsolete status. Confirm lot date codes and storage conditions as availability may be limited. Ensure compatibility with existing board designs regarding pinout and electrical specifications before procurement.

Supervisors Selection Notes

Select this component for applications requiring a 4.63V threshold and integrated watchdog functionality. Consider the TSOT-23-5 package size for space-constrained designs. Evaluate the 140ms reset timeout against system startup requirements to ensure proper initialization timing.

Supervisors Part Context

Part of the CAT823/CAT824/CAT825 family of supervisory circuits designed for basic reset and monitoring functions. These devices maintain a reset output until the monitored voltage reaches the trip value, ensuring stable system operation during power transitions.

Supervisors Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the component is marked obsolete, alternative solutions should be evaluated based on matching threshold voltages, package types, and functional requirements.
