CAT130019TWI-GT3

Supervisors Overview

The CAT130019TWI-GT3 is a voltage supervisory circuit manufactured by onsemi, designed for monitoring system power integrity. It operates within a supply voltage range of 2.85 V to 3 V and features a single monitored input channel. The device utilizes a Microwire serial interface for configuration and status access, allowing communication via dedicated data and clock pins. It is housed in an 8-pin SOIC-wide package suitable for surface-mount applications. The component supports active high and active low output configurations with push-pull drivers, ensuring flexible integration into digital systems requiring precise voltage threshold detection.

Supervisors Feature Summary

• Microwire serial interface for programmable control and status reading
• Single-channel voltage supervision with configurable output polarity
• Push-pull output driver architecture for robust signal driving

Supervisors Applications

• Portable electronic devices requiring battery voltage monitoring
• Embedded systems needing reset signal generation during brown-out events
• Industrial control circuits with strict voltage threshold requirements

Supervisors Procurement Notes

Verify the specific suffix 'TWI' against the target application's pinout and electrical specifications, as variations may exist within the family. Confirm RoHS compliance status through official documentation prior to implementation. Check current lifecycle status, as availability may be limited or subject to last-time buy conditions. Ensure the selected package matches the PCB footprint design constraints.

Supervisors Selection Notes

Select this component when a fixed voltage threshold near 3 V is required for system supervision. The Microwire interface allows for software-configurable outputs, offering flexibility over fixed-function supervisors. Consider the SOIC-8 package size relative to available board space. Evaluate the need for manual reset capabilities if the application requires user-initiated recovery from fault states.

Supervisors Part Context

This part belongs to the CAT1300 series of voltage supervisors from onsemi. The series provides various monitoring solutions with different thresholds and interface options. The CAT130019 variant specifically targets applications requiring a narrow voltage window around 3 V. The TWI suffix indicates the specific package and temperature grade configuration defined by the manufacturer.

Supervisors Replacement Considerations

Direct substitutes include the CAT130019SWI-GT3, which shares similar functional characteristics but may differ in package type or specific electrical tolerances. Verify pin compatibility and interface protocol alignment before swapping components to ensure system stability.
