CAT810MSDI-T3

Supervisors Overview

The CAT810MSDI-T3 is a voltage supervisory circuit manufactured by onsemi, designed for monitoring single-input power supplies. 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 provides a reset delay time of 240 ms and has no manual reset or watchdog timer capabilities. It is housed in a SC-70-3 surface-mount package and functions reliably across an operating temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Provides voltage supervision with an active high push-pull output interface
• Operates without manual reset controls or integrated watchdog timers
• Supports surface-mount installation in compact SC-70-3 packages

Supervisors Applications

• Microprocessor power supply monitoring
• Battery-powered system voltage supervision
• Portable electronic device power management

Supervisors Procurement Notes

Verify the specific threshold voltage variant required for the application, as the CAT810 series includes multiple options. Confirm package availability and lead times through authorized distributors. Check for end-of-life status or obsolescence notices from onsemi before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a low-power, single-channel supervisor with an active high output is needed. Ensure the monitored voltage aligns with the specific threshold version available in the CAT810 family. Consider the SC-70-3 package size constraints for PCB layout compatibility.

Supervisors Part Context

The CAT810MSDI-T3 belongs to the CAT810 series of microprocessor supervisors from onsemi. This series offers various threshold voltages and package options to suit different system requirements. It is part of the broader PMIC category, focusing on reliable power integrity for digital logic circuits.

Supervisors Replacement Considerations

Consult onsemi documentation for direct pin-compatible alternatives within the CAT810 series that match the required threshold voltage. Verify functional equivalence regarding output type and reset delay time when evaluating substitute components.
