CAT810STBI-T

Supervisors Overview

The CAT810STBI-T is a voltage supervisory circuit manufactured by onsemi, designed for monitoring single power supply inputs. It operates within a supply voltage range of 1.2 V to 5.5 V and features an active high push-pull output. The device triggers at a threshold voltage of 2.93 V, with specific under-voltage and over-voltage thresholds of 2.93 V and 2.96 V respectively. It includes a fixed reset delay time of 240 ms and consumes a typical operating current of 6 uA. The component is housed in a compact SOT-23-3 package and supports surface mount installation. It functions without manual reset, watchdog timer, or battery backup switching capabilities.

Supervisors Feature Summary

• Monitors a single input voltage line with active high push-pull output signaling
• Provides automatic system reset upon detection of under-voltage or over-voltage conditions
• Operates with low quiescent current suitable for power-sensitive applications

Supervisors Applications

• Microprocessor power supply supervision
• Portable electronic device power management
• Battery-operated equipment voltage monitoring

Supervisors Procurement Notes

Verify the exact suffix designation (e.g., -GT3) as the base model may indicate generic series data. Confirm availability status since some variants are marked obsolete. Check RoHS compliance details and ensure the package type matches design requirements. Validate that the 2.93 V threshold aligns with target circuit specifications before finalizing procurement.

Supervisors Selection Notes

Select this component when a low-cost, single-channel supervisor is required for voltages near 3 V. Ensure the 240 ms delay meets system startup timing constraints. Verify that the SOT-23-3 package fits the PCB layout. Consider that the absence of manual reset limits flexibility in certain diagnostic scenarios.

Supervisors Part Context

This part belongs to the CAT810 series of microprocessor supervisors from onsemi. These devices are engineered to provide reliable reset signals for digital systems. The series offers various threshold options and packages to accommodate different design needs while maintaining consistent performance characteristics across the family.

Supervisors Replacement Considerations

CAT810STBI-GT3 is a confirmed substitute variant within the same series offering identical electrical specifications and pinout configuration.
