CAT824RTDI-GT3

Supervisors Overview

The CAT824RTDI-GT3 is a single-channel voltage supervisory circuit from onsemi, housed in a TSOT-23-5 surface-mount package. It monitors system voltage with a threshold of 4.38 V and an overvoltage threshold of 4.5 V. The device features a watchdog timer for signal monitoring and provides active high, active low, and push-pull outputs. It operates within a supply voltage range up to 5.5 V and maintains a reset delay of 200 ms. The component functions across a temperature range of -40°C to +85°C with a quiescent current of 6 µA.

Supervisors Feature Summary

• Integrates a watchdog input to monitor system signals and issue resets upon timeout conditions
• Provides flexible output configurations including active high, active low, and push-pull modes
• Maintains reset output until monitored voltage reaches the specified trip value

Supervisors Applications

• Electronic system voltage supervision
• Microprocessor reset generation
• Watchdog timer implementation for system reliability

Supervisors Procurement Notes

Verify component authenticity through authorized channels as availability may vary. Confirm RoHS compliance status prior to integration. Ensure the specific suffix matches design requirements for output configuration. Check for end-of-life notices or obsolescence warnings from the manufacturer before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a single-channel supervisor with integrated watchdog functionality is required. The TSOT-23-5 package suits space-constrained designs. Verify that the 4.38 V threshold aligns with the target system voltage. Consider the 6 µA quiescent current for low-power applications. Ensure the operating temperature range meets environmental specifications.

Supervisors Part Context

This part belongs to the CAT824 series of system supervisory circuits designed by onsemi. These devices provide basic reset and monitoring functions for electronic systems. The series includes variants with different thresholds and output types, all sharing core features like watchdog inputs and manual reset capabilities where applicable.

Supervisors Replacement Considerations

Check for direct pin-compatible substitutes within the CAT824 family with adjusted thresholds. Verify equivalent watchdog and reset timing characteristics. Ensure replacement parts maintain the same TSOT-23-5 package and electrical specifications.
