CAT823YSDI-GT3

Supervisors Overview

The CAT823YSDI-GT3 is a voltage supervisor IC from onsemi, designed to monitor system power integrity. It features a single monitored input with a fixed threshold voltage of 2.19 V. The device provides active high and active low outputs in a push-pull configuration. It is housed in an SC-88A (SC-70-5) surface-mount package. Key functionalities include automatic microprocessor restart after power failure and monitoring of external override signals via pushbutton inputs.

Supervisors Feature Summary

• Automatically restarts the microprocessor following a power failure event
• Monitors external pushbutton inputs for manual override capabilities
• Provides dual output polarity options including active high and active low states

Supervisors Applications

• General-purpose power-on reset circuits
• Microprocessor supervision systems
• Embedded controller reset logic

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm lot traceability and RoHS compliance status prior to integration. Check for obsolescence notices as availability may be limited. Ensure storage conditions meet specified humidity and temperature requirements to maintain device reliability during assembly processes.

Supervisors Selection Notes

Select this component when a fixed 2.19 V threshold is required for single-channel supervision. The SC-88A package suits space-constrained designs needing surface-mount integration. Consider the push-pull output drive capability for direct interface with digital logic inputs without additional buffering components.

Supervisors Part Context

This part belongs to the CAT823 series of voltage supervisors manufactured by onsemi. The series focuses on providing reliable reset signals for embedded systems. The specific GT3 suffix indicates tape-and-reel packaging suitable for automated assembly lines in high-volume manufacturing environments.

Supervisors Replacement Considerations

Cross-reference with CAT823RTDI-GT3 for similar functionality but different threshold characteristics. Verify pinout compatibility and electrical specifications before substituting any alternative voltage supervisor ICs from other manufacturers.
