CAT810MSDI-GT3

Supervisors Overview

The CAT810MSDI-GT3 is a voltage supervisory circuit manufactured by onsemi, designed for surface-mount installation in SC-70-3 packages. It features a single monitored input with an active high push-pull output and lacks manual reset or watchdog timer capabilities. The device operates within a supply voltage range of 1.2 V to 5.5 V, with a specific threshold voltage of 4.38 V. It supports a reset delay time of 240 ms and functions across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides voltage supervision with active high push-pull output signaling
• Operates without manual reset or watchdog timer functionality
• Supports low-power operation suitable for battery-supplied systems

Supervisors Applications

• Portable electronic devices requiring power monitoring
• Battery-operated equipment needing voltage supervision
• Embedded systems utilizing low-voltage logic interfaces

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm package integrity and pin alignment against SC-70-3 specifications. Validate threshold voltage accuracy during incoming inspection. Ensure storage conditions comply with moisture sensitivity levels. Cross-reference datasheet revisions for any parameter updates prior to design finalization.

Supervisors Selection Notes

Select this component when a fixed 4.38 V threshold is required for single-input supervision. Consider the SC-70-3 footprint constraints and active high output polarity. Evaluate thermal performance within the specified operating temperature range. Compare against other CAT810 variants if different thresholds or packages are needed.

Supervisors Part Context

Part of the CAT810 series from onsemi, focusing on simple voltage monitoring solutions. This series offers various threshold options and package types to suit diverse embedded applications. The CAT810MSDI-GT3 specifically targets cost-sensitive designs requiring minimal external components for basic power management tasks.

Supervisors Replacement Considerations

Check for direct substitutes within the CAT810 family offering identical 4.38 V thresholds and SC-70-3 packaging. Verify compatibility with existing board layouts and electrical characteristics before substitution.
