CAT810STBI-GT3

Supervisors Overview

The CAT810STBI-GT3 is a single-channel voltage supervisory circuit manufactured by onsemi, designed to monitor power supply integrity in electronic systems. It operates within a supply voltage range of 1.2 V to 5.5 V and features a specific under-voltage threshold of 3.93 V with an over-voltage threshold of 2.96 V. The device utilizes a push-pull active high output configuration and includes a fixed reset delay time of 240 ms. Packaged in a compact SOT-23-3 surface-mount format, it draws a typical operating current of 6 uA. The component supports an industrial temperature range from -40°C to +85°C and lacks manual reset, watchdog timer, or battery backup switching capabilities.

Supervisors Feature Summary

• Provides continuous monitoring of a single power rail with defined under-voltage and over-voltage detection thresholds.
• Delivers a stable logic signal via a push-pull active high output interface for reliable system integration.
• Ensures deterministic reset timing through a fixed internal delay mechanism independent of input ramp rates.

Supervisors Applications

• Microprocessor power supply supervision
• Portable equipment voltage monitoring
• Industrial control system reset generation

Supervisors Procurement Notes

Verify the obsolete status and limited availability before design finalization. Confirm package compatibility and electrical specifications against current project requirements. Check for end-of-life notifications from the manufacturer. Ensure alternative sourcing channels are identified due to restricted distribution. Validate RoHS compliance documentation for regulatory adherence.

Supervisors Selection Notes

Choose this component when a low-current, single-channel supervisor with a specific 3.93 V threshold is required. The SOT-23-3 package suits space-constrained designs. Consider the fixed 240 ms delay and lack of manual reset when defining system recovery behavior. Evaluate the 6 uA quiescent current against battery life constraints.
