CAT812MTBI-GT3

Supervisors Overview

The CAT812MTBI-GT3 is a voltage supervisory circuit manufactured by onsemi, designed for monitoring power supply rails in electronic systems. It operates within a supply voltage range up to 5.5 V and supports multiple threshold voltages including 2.5 V, 3 V, 3.3 V, and 5 V. The device features an active high, push-pull output and includes a manual reset input. It provides a fixed reset delay time of 240 ms and has a maximum power dissipation of 320 mW. Operating temperatures range from -40°C to +85°C, with a typical quiescent current of 8 µA.

Supervisors Feature Summary

• Provides active high push-pull output for reliable logic interfacing
• Includes manual reset input for user-initiated system recovery
• Offers fixed reset delay to ensure stable power-up sequencing

Supervisors Applications

• Microprocessor power supply supervision
• Portable equipment power management
• Consumer electronics voltage monitoring

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to obsolete status. Confirm RoHS compliance details as specified in official documentation. Check regional availability restrictions before procurement planning. Ensure package integrity matches SOT-143-4 specifications during inspection.

Supervisors Selection Notes

Select this component when an active high output is required for system reset signaling. Consider the 240 ms reset delay for timing-sensitive applications. Verify that the available threshold voltages match the monitored rail requirements. Evaluate the 8 µA quiescent current for low-power design constraints.

Supervisors Part Context

Part of the CAT812 series of voltage supervisors. Shares the SOT-143-4 package with other variants in the family. Designed for single-input monitoring applications without watchdog timer functionality. Manufactured by onsemi under the Catalyst brand lineage.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the CAT812 series. Verify output polarity compatibility if substituting with active low variants. Confirm threshold voltage matching for equivalent protection levels.
