CAT810TSDI-T3

Supervisors Overview

The CAT810TSDI-T3 is a single-channel voltage supervisory circuit manufactured by onsemi, designed to monitor power supply integrity in digital systems. It operates within a supply voltage range of 1.2 V to 5.5 V and features a fixed under-voltage threshold of 2.93 V with an over-voltage threshold of 2.96 V. The device utilizes a push-pull active-high output configuration and provides a reset delay time of 240 ms. It is housed in a compact SC-70-3 surface-mount package and supports an industrial operating temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Monitors a single power supply rail for under-voltage and over-voltage conditions
• Generates a reset signal using a push-pull active-high output interface
• Provides a fixed 240 ms reset delay to ensure stable power-up sequencing

Supervisors Applications

• Digital system power supply monitoring
• Microprocessor power supply supervision
• Embedded controller reset generation

Supervisors Procurement Notes

Verify the specific manufacturer datasheet for the CAT810TSDI-T3 to confirm current production status and electrical tolerances. Ensure the selected component matches the required SC-70-3 package dimensions and thermal characteristics for the target application environment. Cross-reference the threshold voltages with system requirements before finalizing procurement.

Supervisors Selection Notes

Select this component when a fixed threshold supervisor is required for low-voltage digital circuits. The SC-70-3 package offers space efficiency for dense PCB layouts. Verify that the 240 ms reset delay aligns with the startup timing requirements of the monitored microprocessor or logic components.
