CAT863STBI-GT3

Supervisors Overview

The CAT863STBI-GT3 is a voltage supervisory circuit manufactured by onsemi, designed for monitoring single power supply rails. It operates within a supply voltage range of 1.2 V to 5.5 V and features a fixed threshold voltage of 2.93 V. The device provides an active low, push-pull output signal. It is housed in a compact SOT-23-3 surface-mount package. The component supports manual reset functionality and includes a reset delay time of 240 ms. It is rated for operation between -40 °C and +85 °C.

Supervisors Feature Summary

• Provides active low push-pull output for reliable logic interfacing
• Supports manual reset input for system control flexibility
• Operates with low supply voltage down to 1.2 V

Supervisors Applications

• Microprocessor power supply monitoring
• Portable electronic devices requiring low voltage supervision
• Battery-powered systems with single rail oversight

Supervisors Procurement Notes

Verify end-of-life status as the manufacturer indicates this part may be obsolete or discontinued. Confirm availability through authorized distributors or secondary market suppliers like Rochester Electronics. Ensure the specific suffix GT3 matches required packaging specifications. Check RoHS compliance details against current regulatory requirements before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a fixed 2.93 V threshold is required for single-channel supervision. The SOT-23-3 package suits space-constrained designs. Consider the 240 ms reset delay and manual reset capability during system architecture planning. Verify that the 5.5 V maximum operating voltage aligns with the target power rail specifications.

Supervisors Part Context

This part belongs to the CAT863 series of voltage supervisors from onsemi. It is functionally similar to other parts in the family but distinguished by its specific threshold voltage and package type. The series is intended for general-purpose power management applications where simple, reliable voltage monitoring is essential for system stability.

Supervisors Replacement Considerations

CAT853STBI-T3 is listed as a parameter-equivalent alternative available from onsemi. Verify pin compatibility and threshold voltage alignment before substitution.
