CAT130019SWI-GT3-ON

Supervisors Overview

The CAT130019SWI-GT3 is a voltage supervisory circuit manufactured by onsemi, designed for monitoring system power integrity. It features a single monitored input with a threshold voltage range of 2.85 V to 3 V. The device supports active high, active low, and push-pull output configurations. It includes manual reset functionality and integrates a 1 kbit Microwire serial interface for configuration or status reading. Packaged in an SOIC-wide-8 surface-mount format, it operates within standard industrial temperature ranges.

Supervisors Feature Summary

• Integrates a 1 kbit Microwire serial interface for data communication alongside supervision functions
• Provides flexible output drive options including active high, active low, and push-pull modes
• Includes manual reset capability for controlled system recovery

Supervisors Applications

• CPU voltage supervision in embedded systems
• Battery-powered device power management
• Industrial control system monitoring

Supervisors Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm package marking and datasheet revision against original specifications. Check for obsolescence notices from onsemi. Ensure supply chain stability as availability may be limited. Validate pinout compatibility if replacing existing designs.

Supervisors Selection Notes

Select this component when Microwire interface compatibility is required rather than SPI or I2C. Verify that the 2.85 V to 3 V threshold aligns with the target supply rail. Consider the SOIC-wide-8 footprint for PCB layout constraints. Evaluate output type requirements against load characteristics before finalizing selection.

Supervisors Part Context

This part belongs to the CAT13001 series of supervisory circuits from onsemi. It shares functional similarities with other parts in the family but is distinguished by its specific Microwire interface integration. The series typically targets applications requiring combined supervision and non-volatile memory access in compact packages.
