CAT8801SSD-GT3

Supervisors Overview

The CAT8801SSD-GT3 is a single-channel voltage supervisor IC manufactured by onsemi, designed for simple reset and power-on-reset applications. It features a push-pull/totem pole output with an active-low reset signal. The device monitors a single voltage threshold of 2.19V and provides a minimum reset timeout of 140ms. It operates within a temperature range of -40°C to 85°C (TA) and is housed in a compact SC-70-3 surface-mount package.

Supervisors Feature Summary

• Provides reliable system reset via active-low output upon detecting undervoltage conditions
• Ensures stable operation through a defined minimum reset timeout period
• Supports industrial temperature ranges for robust performance in varied environments

Supervisors Applications

• Embedded systems requiring power supervision
• Microcontroller reset circuits
• Portable electronic devices

Supervisors Procurement Notes

Verify component authenticity and datasheet alignment due to potential obsolescence status. Confirm package integrity and storage conditions prior to integration. Cross-reference manufacturer documentation for any recent product change notices or lifecycle updates to ensure long-term supply chain stability and design compliance.

Supervisors Selection Notes

Select this component when a fixed 2.19V threshold and active-low reset are required. The SC-70-3 package suits space-constrained designs. Ensure the 140ms minimum timeout aligns with system startup requirements. Verify compatibility with the target logic voltage levels and operating temperature range before finalizing the bill of materials.

Supervisors Part Context

This part belongs to the CAT8801 series of supervisory circuits from onsemi. The series offers various threshold voltages and packages to accommodate different monitoring needs. The CAT8801SSD-GT3 specifically utilizes the SC-70-3 footprint, distinguishing it from other variants like the SOT-23-3 versions within the same functional family.

Supervisors Replacement Considerations

Check for direct pin-compatible substitutes within the CAT8801 series that match the 2.19V threshold. Verify equivalent reset timeout characteristics and output drive capabilities. Ensure any alternative maintains the same active-low polarity and package dimensions for seamless board replacement.
