CAT823STDI-GT3

Supervisors Overview

The CAT823STDI-GT3 is a system supervisory voltage reset circuit manufactured by onsemi, designed to monitor electronic system voltages and maintain a reset output until the supply reaches the specified trip value. It features an internal timer of at least 140ms to allow power supply stabilization. The device supports manual reset via pushbutton override and automatically restarts microprocessors after power failure. It operates within a temperature range of -40°C to +85°C and is available in a TSOT-23-5 package.

Supervisors Feature Summary

• Provides accurate under-voltage system monitoring for 3.0V, 3.3V, and 5.0V systems
• Includes a watchdog timer and manual reset capability for external override
• Automatically restarts microprocessor following power failure events

Supervisors Applications

• Microprocessor and microcontroller-based systems
• Intelligent instruments and control systems
• Critical microprocessor monitors
• Portable equipment requiring brownout detection

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to End-of-Life status. Confirm package integrity and pin alignment against datasheet specifications. Check for manufacturing date codes and lot traceability. Ensure storage conditions comply with moisture sensitivity levels prior to reflow soldering. Validate replacement availability if current stock is insufficient for production needs.

Supervisors Selection Notes

Select this component for designs requiring basic voltage supervision with manual reset functionality. It is suitable for applications needing brownout detection across standard logic voltage levels. Consider the TSOT-23-5 package size for space-constrained layouts. Verify compatibility with existing MAX823/24/25 footprints if cross-referencing legacy designs.

Supervisors Part Context

The CAT823 series belongs to onsemi's standard product line of supervisory circuits. It serves as a cost-effective solution for essential power management tasks in embedded systems. The device is pin-and-function compatible with industry-standard alternatives like the MAX823, facilitating easier design transitions and upgrades.

Supervisors Replacement Considerations

The CAT823STDI-GT3 is functionally equivalent to the MAX823. Designers may consider direct pin-compatible substitutes from other manufacturers that adhere to the same electrical characteristics and timing requirements for seamless integration.
